Method of Operation
Before operating the unit please ensure that you are aware of all hazards relating to the
system and environment in which it is operating, and that you have complied with all
necessary safety regulations and precautions.
Remove the key from the mains on/off switch before making any connections. This will ensure
that the unit is off because the key may only be removed in the off position. The key is
trapped in the on position.
Connect the equipment as described in section 2.2, keeping the test object earthed at all times
using the earth stick provided.
Remove the earth connection from the test object before applying the test voltage to the test
object.
Connect the mains supply to the unit.
Switch the main power key switch on. This will cause the following indicators to illuminate:
Mains on indicator
HV off green indicator in HV off pushbutton
Variable overload indicator in variable overload reset switch
Interlock/E-stop reset switch
Press the variable overload reset switch to reset the trip. Ensure that all external interlocks are
closed and the front panel Emergency stop and any external E-stops are released. Press the
interlock/E-stop reset switch to arm the circuit.
Set the desired kV meter range, and set the variable overload to the desired trip level.
Before commencing testing set the regulator to the fully anti-clockwise (minimum) position.
Press the HV output on pushbutton. The HV output off (green) indicator will extinguish and the
HV on indicator (red) will illuminate.
The HV output level can now be increased to the desired level.
In the event of a test object failure the HV output will be automatically switched off by the
protection system.
When the test is completed, turn the regulator control knob fully anti-clockwise and switch off
the HV output and then the main supply.
Re-apply the earthing stick to the test object.
Before disconnecting the test object ensure the HV connection is grounded using the earthing
stick provided.
