HZQ AC Hipot SF6 Gas Inflated Type Power Frequency Testing Transformer

Technical parameters of HZQ series alternating current test transformers

The operation of the insulation test with HIPOT tester is as follows:

1) Please make grounding connection for sample object, HV transformer and main control box first

2) Please discharge the sample object if the sample object is a capacitive equipment.

3) Please make connection for tester and sample object according to figure 3.

4) Please make power connection for main control box.

5) Confirm the high voltage value in withstand.

6) Setting the protection value of current by the pointer on the over current protection relay panel.

7) Adjust the regulator to zero position and then press down the close button on the panel the tester with enable the high voltage output unit.

8) If the regulator is not at zero position when you press down the close button the high voltage output unit would not be enabled. 

There is a zero position indicator light on the panel of the main control box.

9) Adjust the high voltage output to the withstand test value step by step. Read the high voltage value and LV current from meters at the same time.

10) Start the timer by the timer switcher on the main control box panel when the high voltage has.

11) If the current over the value set on the panel of the over current relay the tester would cut off the power supply of HV transformer immediately. It is said the test result is failure.

12) If the timer display value reach the set value the tester would have a sound alarm to inform operator that the withstand time is ok. If the tester has not start the over current protection unit before sound alarm it is said the test result is ok.

13) Open the power supply of HV transformer by press down the "open" button on the panel of the main control box when test is end.

14) Please discharge the high voltage circuit of sample equipment before remove off the cable connection of high voltage circuit.

Please do not start the test if some part of the tester had been destroyed.
