2. Set the Voltage Range switch (item 14) to the desired range either 16 or
32kV.
3. Set the Test Mode selector switch (item 16) to the PROOF/BURN &
SURGE group. Both pushbuttons’ Blue LEDs will illuminate, indicating that
either of these test modes are available.
4. Push the PROOF/BURN pushbutton (item 17). Selection is confirmed by
the PROOF/BURN pushbutton Blue LED remaining illuminated, and the
SURGE pushbutton Blue LED extinguishing. The HV ON Pushbutton
(item 10) Green LED will illuminate.
5. Push the HV ON pushbutton (item 10) and the selected test voltage will be
applied to the cable under test. The HV ON Green LED will go out and the
Red LED of the HV OFF pushbutton (item 9) will come on.
6. The required test voltage is set by using the Voltage Control knob (item 12).
This voltage is displayed on the D.C. Kilovolt meter (item 22).
7. If the fault needs conditioning (burning), then the operator leaves the
proof/burn voltage applied, rather than removing it after a breakdown,
which would be the normal practise when checking the integrity of a cable.
Following a suitable test period as defined by the operator the voltage is
removed.
8. Push the HV OFF pushbutton (item 9) and the selected test voltage will be
removed from the cable under test. The HV OFF pushbutton Red LED will
go out and the HV ON pushbutton (item 10) Green LED will come on. The
unit will remain in the PROOF/BURN test mode without any voltage output
until a different test mode is selected...
9. To deselect the test mode, push the PROOF/BURN pushbutton (item 17),
which also engages the internal earthing/grounding and removes any High
Voltage. Both the PROOF/BURN & SURGE test Mode pushbuttons’ blue
LEDs will illuminate, indicating that either of these test modes are now
available for selection.
