COMMISSIONING TEST ENVIRONMENT
2.1 Important
notes
All commissioning tests of
MiCOM P120, P121, P122
and
P123
relays are carried out by
injecting currents to the secondary of the earth and/or phases CTs using appropriate
injection test sets provided for this purpose.
2.1.1 Injection
test
sets
For reasons of convenience (weight, spatial requirement, transportation), a single-phased
injection test set is more suitable for commissioning and is able to perform all commissioning
tests regarding
MiCOM P120, P121, P122
and
P123
relays.
Thus, the following descriptions indicate how to conduct the commissioning tests with a
single-phase injection test set.
However, for certain commissioning tests, the three-phase wiring diagrams are easier to
understand and in this case the description is also given in three-phase format.
Single-phase injection test set
1 current (0 to 50 A), timer (precision 1 ms).
Three-phase injection test set
3 currents (0 to 50 A), timer (precision 1 ms).
2.1.2
Additional commissioning test equipment
−
1 multimeter (precision 1%),
−
1 connecting terminal to measure the currents exceeding 10 A (precision 2%),
−
Test plugs and wires to carry out injections to the CT's secondary (dimension
according to the currents injected).
2.1.3 Communication
For all commissioning tests, the records can be made by using the RS 485 communication
on the rear connector of the
MiCOM P120, P121, P122
and
P123
relays or for
MiCOM P122
and
P123
using the RS232 front port.
According to each RS 485 communication protocol (MODBUS, Courier, IEC 60870-5-103,
DNP3.0).
2.2
Commissioning test sheets
Commissioning test sheets are available in the APPENDIX 2 of the Technical Guide.
The presentation of the Commissioning test sheets follows the description of the tests of this
chapter.
The contents of these Commissioning test sheets enable you to log:
The name of the relay, station and circuit
The characteristics of the
MiCOM P120, P121, P122
and
P123
relays
The various settings
The results of the protection and automation checks
The result of the test records after commissioning.
