INITIAL SET-UP--ELECTRICAL
NOTE: The external interlock circuit must consist of a closed loop of dead contacts; an open circuit
prevents the high voltage output from being energized. When the control power is on, the external
circuit will be energized with 120 volts AC.
4. Connect signal / metering cable between High Voltage Transformer TX1 connector and TX1 connector
on the controls.
5. Connect the power cable from the High Voltage Transformer to the ‘Output to Transformer’ connection
on the control box.
6. Connect the test object to the output termination of the high voltage transformer using supplied output
cable. Ensure that the ground connection is applicable for test level and type of test and that the
connection has sufficient safety clearances for the voltage rating. Two high voltage output connections
are possible:
50kV, 200mA: The 50kV tap is located on the side of the high voltage cylinder. Set the Measurement
Divider switch (See Section 4) to the 50 kV/200mA position when using this output.
This sets the metering and overload properly for the output being used.
100kV, 100mA: The 100kV tap is located on the top of the high voltage cylinder. Set the Measurement
Divider switch (See Section 4) to the 100 kV/100mA position when using this output.
A wire can be used to make this connection; however, for best results (less corona leakage current),
route a wire down the center of a one-inch diameter pipe (aluminum or copper) and solidly connect the
ends of the wire to the output tap and the test specimen. The pipe should also be solidly connected at
each end.
7. Connect the input main power cable to the Main Input connection at the control box and then to the
facility power source.
