with the particular switchgear only.

6.1 Commissioning
6.1.1 Preparatory work

In preparation for commissioning, the following 
work is to be performed prior to connection 
with the high voltage power supply:

•  

Connect the supply and control voltage 

and check the correct polarity

•  

Check mechanical and electrical interlocks for 

compliance with the specified conditions

•

devices (observe DIN VDE 0141)

•  

Check the general condition of the 

switchgear and external conditions for 
detrimental factors of any kind

•  

Display the instructions for handling SF6 in 

the switchroom. The handling specifications 
for SF

6

 also apply accordingly to nitrogen (N2)

•  

Display the ABB instruction manual on the 

handling of insulating gas and behaviour 
during faults in the switchroom 

•  

Instruct the local operators on the 

fundamental details of operating the 
switchgear in normal service

•  

Check the readiness for operation and the 

switching condition of the upstream and 
downstream electrical equipment

•  

Perform further checks where necessary on 

the following equipment from the areas 
adjacent to the switchgear
-  Power cables
-  Control wiring
-  Supply voltage and its polarity
-  Remote controls
-  External earth with connection to main 

earthing bar (3.1)

-  Switchroom equipment
-  Switchroom condition

6.1.2 Initial start-up

•  

Comply with all relevant safety regulations

•  

Ensure that the switchgear circuit-breakers 

are in the OFF position

•  

Close the disconnector for the relevant 

busbar system

•  

Cancel any existing short-circuiting and earthing 

connections in the critical switching area

•  

Check that corresponding conductor sections 

are in line where relevant with several 
incoming feeders and switchgear sections

•  

Energise the switchgear step by step

•  

Check measurements and functions 

dependant on high voltage

•  

Look out for irregularities of any kind

6.2 Switching operations
6.2.1 Circuit breaker
(Figures 3/7, 6/1, 6/2, 6/4)

The circuit breaker is fitted with a charging 
motor. Charging of the spring energy storage 
mechanism takes place automatically.

Opening and closing the circuit breaker

•  

Closing and opening are effected by 

operation of the devices fitted

•  

ON-OFF switching operations may only be 

performed with the control cabinet door closed

Opening the control cabinet door 
constitutes intervention in the interlock 
system. Opening of the control cabinet 
door can constitute intervention in the 
interlock system (see sections 3.8 to 3.10).

•  

Observe the position indicator

Manual charging of the stored-energy spring

1. On failure of the charging motor,the charging 

process can be performed or completed by 
hand:

•  

Open control cabinet door (4.3)

•  

Insert charging lever (6.3) into recess (1.40) 

and pump for approx. 25 strokes until the 
charged condition is displayed

When the charged condition is reached, the 
charging mecha nism automatically 
disengages and further strokes of the 
charging lever have no effect.

6  Commissioning/operation

Key to the charging condition displays:

2. If the control voltage fails with the circuit 

breaker closed, it is possible to open it using 
the mechanical OFF push button (1.35).

Emergency operation of the mechanical ON 
pushbutton for the circuit breaker operating 
mechanism on failure of auxiliary voltage 
(figure 6/6b)

Caution: Interlocks are cancelled during 
this operation. Only open or close circuits 
with the circuit breaker! The three position 
switch must be in a limit position !

Release the fastening screws in the circuit breaker 
cover and remove the cover. Use a suitable tool 
to press the pin in the blocking magnet (2.41) to 
the right and simultaneously move the slide 
(2.42) to close the circuit breaker.

Note

On failure of the control voltage, there is 
no maloper ation protection for the circuit 
breaker and three-postion switch during 
emergeny manual operation

6.2.2 Three-position switch
(Figures 3/7, 6/1, 6/3 and 6/5)

•  

The three position switch  (2.1)  is fitted with 

a motor-operated mechanism. Opening and 
closing are effected by selection on the 
multifunction protection and switchbay 
control unit or by means of the devices fitted

•  

Routine opening/closing operations 

may only be performed with the control 
cabinet door closed. Opening of the 
control cabinet door can constitute 
intervention in the interlock system (see 
sections 3.8 to 3.10)

•  

Observe the switch position indication on the 

electrical position indicators

•  

Sensors 2.28 to 2.31 or microswitches 2.37 to 

2.40 on the three position switch operating 
mechanism detect the switch positions
-  Disconnector (-Q1) ON and OFF
-  Earthing switch (-Q5) ON and OFF

Emergency manual operation

In place of motorised operation, the switching 
process can also be initiated and completed 
manually.

Caution!
Intervention in the interlock concept is 
possible by opening the control cabinet door.

•  

Switch the three-position switch on or off 

manually

This requires the following actions:
-  Open the control cabinet door
-  Switch the circuit breaker off
-  With the " mechanical interlock between 

circuit breaker and three position switch " 
option, opening flap (2.22) on the three 
position switch operating mechanism 
activates a mechanical interlock between 
the two devices

Note

The flap (2.22) can only be opened when the 
circuit breaker is OFF.

•  

Prior to emergency manual operation, switch 

off the mcbs for the circuit breaker release 
circuit and for the operating mech anism of 
the position switch

•  

Insert the crank (6.1) in the hollow shaft (2.26)

•  

A cam fitted at the crank prevent in cooperation 

with a bolt which is routed at the operation 
mechanism to run over the middle position

•  

Three-position switch operation

If the three-position switch is in the central 
position (i.e. disconnector and earthing switch 
OFF), the disconnector can be closed with 
approx. 24 clockwise turns, and the earthing 
switch with approx. 24 anti-clockwise turns. 
If the " earthing switch ON " position is to be 
reached from the " disconnector ON " position, 
or vice versa, the crank is to be removed in the 
self-inhibiting central position (disconnector 
and earthing switch OFF) and refitted. When 
the  crank is refitted, the further switching 
operation is automatically enabled.

Note

Always perform every switching operation right 
up to the stop in the relevant limit position.

•  

Close flap (2.22) again

If the hand crank is withdrawn in an intermediate 
position, the flap cannot be closed.

This intermediate position can be seen on the 
one hand by the lack of a mechanical limit 
position indication for the three position switch 
and also by the electrical displays on the front 
door.

The limit positions are only correctly indicated 
when the switch is in a limit position, i.e. when 
the contacts have full current carrying capacity. 
The flap (2.22) can then be closed and the circuit 
breaker switched on.

When the circuit breaker is open, the flap can 
also be opened in an intermediate position 

and the hand crank fitted to permit manual 
completion of a switching operation.

The specific data for the relevant order are 
also to be observed.

Note

When the flap (2.22) is open, the circuit breaker 
is mechanically and electrically blocked in the 
OFF position

•  

Close the control cabinet door

Emergency manual operation of the three position 
switch in a riser panel on failure of auxiliary voltage 
(optional mechanical interlock) (figure 6/6a)

Caution: Interlocks are cancelled during 
this operation. Only open or close circuits 
with the circuit breaker! The three position 
switch must be in a limit position! 

The flap (2.22) is released and access to the 
emergency manual operation shaft provided by 
pulling the interlock pin on the blocking 
magnet (2.41).

6.2.3 Undervoltage release

Undervoltage releases may be fitted as an 
option. In order to prevent the circuit breaker 
being opened by the undervoltage release on 
power failure with tee-off earthing, a tie wire is 
provided.

6.3 Observation of the display and monitoring 

facilities

6.3.1 Gas monitoring
(Figures 6/1, 6/7)

All high voltage compartments in the switchgear 
must have a sufficient insulating gas pressure 
during operation. The minimum funcional level 
for insulation is listed in section 2.1. This is  
monitored by sensors (1.8) and (2.3).

If the gas pressure falls below the alarm level for 
insulation, a LED on the multifunction protection 
and switchbay control unit signals that the gas 
should be topped up. With conventional  panel 
control, the issue of the signal is optional and 
dependent on the individual project.

Note

If a panel is isolated for a relatively long period 
(several weeks), mcb (F116) for the auxiliary 
voltage supply to the must remain on. Only in 
this way monitoring of  the  insulating gas is 
ensured. With conventional panel control, the 
details in the order documents are to be observed.

Details on the gas system of the ZX1.5-R switchgear  
can be found in instruction manual.

6.3.2 Electrical/mechanical display/monitoring

During operation of the switchgear, observe all 
visible operating data and condition displays in 
the secondary system and watch out for 
irregularities of any kind, including the external 
conditions of the switchgear.

6.4 Test procedures
6.4.1 Testing for the off-circuit condition

The panels are fitted with the low impedance, 
capacitive voltage indicator system for testing 
of the off-circuit condition.

For details, see VDE 0682 Part 415, or IEC 61243 
Part 5.

Note

Only display units which comply with the 
IEC or VDE standards and the technical 
design of the indicator system in the relevant 
switchgear may be used!

Note

The measuring sockets must on no account 
be short-circuited, except during voltage 
testing of the system (e.g. with power 
frequency withstand voltage or impulse 
withstand voltage)!

Testing for the off-circuit condition is performed 
with a plug in display unit at corresponding pairs 
of measuring sockets (1.6) and optional at (4.5) 
(Front side).

Use of the display unit

•  

Perform a functional test on the display unit 

immediately before and after use, e.g. with 
interface tester. The display must be clearly 
visible

•  

The presence of operating voltage is indicated 

by a signal

•  

Observe the individual operating instructions 

for the display unit for the relevant switchgear

Interface testing

•  

Perform interface testing as a functional test 

on all coupling components, e.g. with interface 
tester

•  

The interface test is a repeat test to IEC 61243 

Part 5 or VDE 0682 Part 415

6.4.2 Testing for the in-line condition

Testing for the in-line condition, e.g. when there 
is more than one incoming feeder, can be performed 
with a suitable line comparator at  measuring 
sockets (1.6 and 4.5 respectively) on the capacitive 
voltage indication system.

Test procedure:

•  

Only use line comparators which comply with 

the IEC or VDE specifications and the technical 

design of the display system in the relevant 
switchgear

•  

Perform a functional test on the equipment 

at the start of testing

•  

Do not exceed the maximum permissible length 

of measuring leads per line

•  

Connect the measuring leads precisely assigned 

to the corresponding main conductor sections

•  

Always follow the details in the operating 

instructions for the line comparator

6.4.3 High voltage tests

(Figures 3/7, 6/1, 6/6)

The test plugs available for high voltage tests, 
shown in figure 6/6, are suitable for the following 
applications up to and including 27.5 kV rated 
voltage.

Optional test cables can be used for high voltage 
tests.

On account of the sensor technology used and 
the multifunction protection and switchbay 
control unit, the test voltage must not exceed 
the following levels:

•  

Insulation testing of the switchgear at the 

relevant power frequency withstand voltage 
(The voltage value in site shall not exceed 
80% of the following value) 

-  

27.5 kV switchgear: 95 kV

Performance of voltage test plugs

•  

Isolate the switchgear area in accordance 

with the safety rules according to VDE 0105/EN 
50110 and secure it to prevent reconnection

•  

Verify the off-circuit condition with a suitable 

hand-held display unit at measuring sockets 
(1.6) or (4.5) on the capacitive voltage indicator 
system

•  

Unscrew surge arresters where fitted and close 

off the exposed sockets with insulating cable 
dummy plugs

•  

Close off empty cable sockets with insulating 

cable dummy plugs

•  

Check the test plug to ensure that the surface 

is clean and dry, and clean it if necessary

•  

Grease the insulating part of the test plugs in 

accordance with the instructions

•  

Unscrew cable dummy plug (1.5) in the relevant 

test socket (1.4) and remove it

•  

Connect an earthing lead to the test plug, 

following the instructions on safety at work 
in figure 6/7

•  

Insert the test plug into the prepared test socket 

and screw it tight

Notes

•  

Only fit the test plugs for voltage tests for 

the duration of those tests

•  

Short-circuit the measuring sockets (1.6) 

or (4.5) in the panels concerned for the 
duration of the testing process at test 
voltages up to rated power frequency 
withstand voltage

•  

For performance of cable tests, in the switching 

condition" tee-off " disconnected and earthed, 
earthing of  the cable has to be cancelled by 
opening the circuit breaker. This is accom 
plished by using the mechanical OFF button to 
open the circuit-breaker (see also Section 3.10)

6.4.4 Protection tests by primary current injection

(Figures 6/1 and 6/7)

In testing of protection functions by primary 
current injection, the primary current is conducted 
into the panel via the test sockets. Current test 
plugs, which are to be fitted as described below, 
are inserted in the test sockets.

•  

Observe the manufacturers instructions for 

current test plugs

•  

Isolate the relevant area of the switchgear in 

accordance with the safety regulations of 
VDE 0105/EN 50110 and secure it to prevent 
reconnection

•  

Check the off-circuit condition with a suitable 

(hand-held) indicator unit at the measuring 
sockets (1.6 or 4.5) of the capacitive voltage 
indicator system

•  

Check the test plugs to verify that the surface 

is clean and dry, and clean them if necessary

•  

Unscrew and remove the cable blanking plug 

(1.5) in the relevant test socket (1.4)

•  

Insert the test plugs into the empty test sockets 

and screw them tight

•  

Assemble the test apparatus in accordance with 

the directions from the protection test equipment 
manufacturer and perform the protection test

•  

As soon at the test is complete, remove the 

current testing plug and replace it with an 
insulating blanking plug

Note

Voltage may only be applied to the OFF 
release coil of the circuit breaker (shunt 
release OFF) for a period of 1000 ms. If this 
period is exceeded, the coil will be burn out. 
For this reason, the protection testing system 
must be shut down by the OFF release 
disconnected.

Caution!

If the circuit breaker is to be included in 
the test, it must be taken into account 
that earthing via the circuit-breaker is 
cancelled when the breaker is opened !
To prevent this, the release coil is to be 
disconnected prior to testing.

6.4.5 Maintenance earthing

•  

Earthing of the busbar with the bus tie/riser, 

as described in section 3.10

•  

Earthing with an earthing and short-circuiting set

Handling during earthing with an earthing and 
short-circuiting set:

(Figures 6/1 and 6/7)
The plugs shown in figure 6/7 in conjunction with 
corresponding short-circuiting and earthing cable 
sets are to be used for maintenance earthing. 
The short-circuit withstand capability of the 
cable set must correspond to the conditions of the 
switch-gear installation.

Caution!

Observe the notes in Section 3.8 on the interlock 
dependencies for all work with earthing and 
short-circuiting sets!

•  

Isolate the switchgear area in accordance with 

the safety rules of VDE 0105 and secure it to 
prevent reconnection

•  

Verify the off-circuit condition with a 

suitable (hand- held) display unit at 
measuring sockets (1.6) or (4.5) on the 
capacitive voltage indicator system

•  

Unscrew surge arresters where fitted and 

close off the exposed sockets with insulating 
cable dummy plugs

•  

Close off empty cable sockets with insulating 

cable dummy plugs

•  

Check the test plugs to ensure that the surface 

is clean and dry, and clean them if necessary

•  

Carefully screw the short-circuiting and earthing 

cable set to the test plug

•  

Connect the common earthing connector of the 

cable set to the earthing terminal of the panel

•  

Unscrew cable dummy plugs (1.5) in the relevant 

test socket (1.4) and remove it

•  

Insert the test plugs into the prepared test 

sockets and screw them tight

6.5 Safety note on operation of the voltage 

transformers

The screws marked in figure 5/13 establish the 
earthing connections to the relevant cable 
terminals in the terminal box shown (illustration 
shows condition as delivered).

The wiring and in particular the earthing of the 
secondary terminals is to be implemented in 
accordance with the circuit diagrams!

Releasing the earthing screw on the "N" 
terminal leads to potentially lethal high 
voltage at the terminal during operation 
of the voltage transformers!

Releasing earthing screw "N" is only 
permissible when the voltage transformers 
are off-circuit on the primary side (for test 
purposes)!

The relevant switchgear section is to be isolated 
and earthed before the isolating system for the 
voltage transformers is operated! (The 5 VDE 
safety rules are to be observed.)

Always use original earthing screws!

6.6 Application of the X-ray regulations

One of the physical properties of vacuum 
insulation is the possibility of X-ray emissions 
when the contact gap is open. The specified type 
test performed by the Physikalisch-Technische 
Bundesanstalt (PTB) in Brunswick in Germany 
demonstrates that the local dosage output of 1 

μSv/h at a distance of 10 cm

 from the touchable 

surface is not exceeded.

The results are as follows:

•  

The use of the vacuum interrupters at rated 

voltage is completely safe

•  

Application of the rated power frequency 

withstand voltage specified for the switching 
device by VDE 0670 and IEC 62271 or a DC voltage 
of 48 kV or 70 kV during cable tests is also safe

•  

Higher voltages than the rated power frequency 

withstand voltage specified in DIN VDE or IEC 
standards or the DC voltage must not be 
applied

•  

Fulfillment of the above requirement with the 

vacuum interrupter in the open position is 
dependent on maintenance of the specified 
distance between the contacts (which is 
automatically ensured with correct mechanism 
function and force transmis sion)
