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.

8

Too much deviation for high and low terminal ammeters

Whether low battery at high terminal ammeter.

2. Whether caused by corona.

3. Whether caused by insulation characters of flexible cable.

9

No-load voltage increase, large current leakage.

Too close to objects on the ground.

Dirty insulating cylinder. Clean the cylinder surface.

3. Too large corona current.

10

Unable to increase to rated voltage.

Turn overvoltage knob clockwise to maximum

11

unable to increase voltage, over-current always occurs

Check whether ground wire is removed.

Operation begins after green light for voltage increase is on.

3. Whether shielding wire of high voltage cable is grounded.

12

High terminal micro ammeter is always zero.

Whether the black line of shielding layer and the red line of core wire is connected.

2. Whether one side of the red clip is disconnected at the root.

13

fast loading line is difficult to connect

Check alignment pin

Press and turn clockwise

3. Whether leading line inside socket is bent.

14

Over-current occurs before reaching rated voltage.

Check whether grounding wire is removed.

Whether operation begins after green light for voltage increase is on.

3. Insufficient insulation distance causes discharge.

15

Over-current often occurs during zinc oxide arrester tests.

1. Whether caused by too rapid voltage increase at turning point. Adjust the knob slowly at turning point.

16

Unstable current during capacitive tests.

1.Whether caused by HV equipment to test 10 kV cable.

2. Sudden unstable currents are mostly caused by break of inner wire in fast loading multi-core cable.

17

Voltage increases from non-zero state after turning knob clockwise

Caused by inner shield of line 1 and 2, break of line 4 and 5 in fast loading multi-core cable

18

Picture missing on LCD

Partial damage of LCD, return to factory for replacement.

19

No current at rated voltage

Check whether output core wire is broken

20

Ammeter data exists in control box, but there is no current display

The clip should be suspended in the air.

No.
