CONTROLS AND INDICATORS
High Voltage Section
Descriptions are keyed to Figure 3-2.
1.
Power Connector
– Power Cable from Output to Transformer connector, connects here.
2.
High Voltage Unit Ground Point
- A Ground cable from facility ground or earth ground must be
connected here.
3.
Guard Binding Post (GRD) -
Currents associated with this connection bypass the current meter
(meter bypass connection).
SEE SECTION: 6--GROUND-GUARD-RETURN CONNECTIONS for more information on these
connections (Page 6
– 1).
4.
Ground Binding Post with Jumper Clip (GND) -
This binding post is connected to ground. When
the Jumper Clip is tied from Ground to Return (RTN), any leakage currents from High Voltage to
Ground will also be measured by the Current Meter. When the test specimen is grounded or has any
sort of ground reference, the Jumper Clip must be connected from Ground to Return.
When the Jumper Clip is tied from Ground to Guard (GRD), any stray leakage currents associated
with Ground or Guard will bypass the Current Meter and will not be measured. The test specimen
must be totally isolated from ground and free of ground references to use the Jumper Clip in this
position.
Note:
The Jumper Clip
must always
be connected from Ground to either Return or Guard as desired
or dictated by the test set up.
5.
Return Binding Post (RTN)
- Low potential side of test specimen connects here. This connection
routes current through the Current Meter circuit (metered connection point).
6.
TX1 Connector
- Signal / Metering cable connects from here to TX1 on Control / Regulator section.
7.
36 kV TAP
- For 0
– 36 kV output at 0 – 180 mA, this connection must be used and measurement
divider switch on controls must be set to 36 kV/180 mA position.
8.
130 kV Tap -
For 0
– 130 kV output at 0 – 50 mA, this output connection is used and measurement
divider switch on controls must be set to 130 kV / 50 mA.
