transformer, but also the HZJZ test transformer. But, when performing the alternating
current pressure test, don’t pull out the short circuit pole on the high compression leg.
2. Wiring schematic drawing of direct current leak and direct current pressure test.
Explanation:
2.1. Engage in the direct current leak and direct current pressure test, it should only use
the HZJZ test transformer and pull out the short circuit pole worked on the high
compression leg.
2.2 When do the electric cable pressure, not to combination capacitance in stead of
potentiometer
，
it should read value of the high pressure voltage exactly and it is very
intuitionistic.
2.3 When the direct current is leaked, the microampere meter may direct readout the
value of the direct current pressure test.
2.4 Complete the direct current leak, may carry out direct current pressure test directly
without taking out stitches.
2.5 Need to add capacitance when doing arrester test.
3. Series Excitation Combination Test Transformer Wiring.
3.1 When carry out alternating current series high frequency voltage test transformer, may
form test transformer with high voltage compounding a few set of HZJ . This principal is
