Method of Operation
Connect the equipment as described in
Section 2.2
.
Remove the mains power switch operating key before connecting the equipment to the main
supply. This will ensure the equipment is in the OFF position as the key is only removable in
that position.
Once the equipment is connected to the mains supply the key operated switch can be turned to
the ON position. The following will now occur:
a. Power ON lamp will be lit
b. HV OFF lamp will be lit
c. The Digital Meters will boot up.
d. The variable overload reset lamp will be lit
Press the variable mA Trip reset push-button thus arming the circuit. The indicator lamp in the
reset push-button will go out thus indicating that the circuit is armed.
Check that the primary trip circuit breaker is closed and the external interlock circuit is closed or
the shorting plug is fitted.
Set the desired overload mA trip level.
If required, set a desired test time.
Before commencing a test ensure that the regulator is in the fully anticlockwise position at ‘0’.
Depress the HV ON push-button - this will close the internal circuit breaker. The HV OFF lamp
will extinguish and the HV ON lamp will be lit. The output voltage can now be increased to the
desired level as indicated on the kV meter.
In the event of a test object failure the HV output will be automatically switched off by the
protection system. Depending on the level of the fault, either the electronic trip or the primary
trip circuit breaker will operate.
When the test is completed, turn the regulator control knob fully anti-clockwise and switch off
the HV output and then the main supply.
It is best practice to ‘0’ the regulator control knob after each test.
Before disconnecting the test object ensure the HV connection is grounded using the
earthing stick provided.
