HZZGF 60kV 2mA DC Hi-pot Tester

HZZGF 60kV 2mA DC Hipot Tester utilizes high-frequency pulse width modulation (PWM) technology, enabling closed-loop adjustment with high voltage stability, a low ripple factor, and a fast, reliable protection circuit. One standout feature of the DC Hipot Tester is its ability to deliver high-voltage output, enabling comprehensive testing of cables, transformers, motors, and other electrical devices. This capability not only identifies potential insulation failures but also helps prevent costly downtime and ensures compliance with industry regulations.

DC Hi-pot Tester Common Fault And Solution

	Fault Phenomenon	Solution
1	The power indicator light is on.	Replace ACRD fuse. If burnout again, check whether the power supply is over 380v. If so, remove the varistor, then the product can be used for emergency.
2	Green light is on but HV does not increase.	Check if fast loading multi-core cable line 6 and 7 are disconnected. If HV increased suddenly after turning the knob clockwise for a few circles, then the problem lies in the fast loading multi-core cable.
3	Adjusting knob is turned to zero and voltage-increasing switch is on, but there is no indicator light.	Check if fast loading multi-core cable line 1 and 2 are disconnected.
4	Voltage is increased but there is no display.	Check if fast loading multi-core cable line 1 and 2 are disconnected.
5	Current exists but there is no value display	Check if fast loading multi-core cable line 3, 4 and 5 are disconnected.
6	voltage display is unstable after voltage increase (non-capacitive test)	Check if fast loading multi-core cable line 3, 4 and 5 are disconnected.
7	Over current always appears in large capacitive tests	Whether operation begins after green light for voltage increase is on. 2. Whether stop for 2 seconds at 3/4 circle. 3. Whether hv cable has short circuit to earth.
