Instrument Components:

1. High-voltage pulse generator main unit: Applies high voltage to the cable under test and outputs a high-energy pulse signal;

2. High-voltage output line (5 meters): Connects the high-voltage output terminal of the main unit to the core of the cable under test;

3. Ground wire (5 meters): Connects the sampling ground, high-voltage ground, and discharge rod to the earth;

4. Power cord (2.5 meters): The instrument's operating power cord;

5. Discharge rod: Performs DC current-limited discharge or DC short-circuit discharge on the cable under test;

6. Fuse: Backup fuse for AC220V power supply system (8A fuse);

7. Auxiliary ground wire (2.5 meters) and grounding probe: If the on-site power supply is not grounded, a poor grounding status will be detected (red light). A grounding probe and auxiliary ground wire are needed to connect the safety grounding terminal of the power supply to the earth. This facilitates the measurement of the grounding status between the high-voltage output side and the power supply terminal.









Panel introduction
1. Ammeter: Indicates the magnitude of the current.

2. Voltmeter: High-voltage output voltage indicator (kV), available in 8kV, 16kV, and 32kV, with readings via a voltage level switch.

3. Grounding Indicator: Green light indicates good grounding, yellow light indicates poor grounding, and red light indicates no grounding.

4. Power Indicator: Illuminates when the power switch is turned on.

5. Zero Indicator: Indicates the voltage adjustment knob is in the zero position. High voltage can only be activated when the zero indicator is lit.

6. High Voltage Indicator (HV): Illuminated indicates high voltage output; off indicates no high voltage output.

7. Power Switch: Rotate clockwise to turn on system power, and counterclockwise to turn off system power.

8. Grounding Test Switch: Rotate clockwise, hold for 3-5 seconds, and observe the grounding indicator light status.

9. Discharge Period: Three discharge interval options are available: 3 seconds, 6 seconds, and 9 seconds.

10. Mode Selection: Three modes are available: DC (withstand voltage), Single, and Cycle. DC is the withstand voltage function; when selected, the cable undergoes a withstand voltage test. Single is the manual function; when selected, the high voltage is increased after startup, and pressing the Single button allows manual triggering of the impulse discharge. Cycle is the automatic function; when selected, the high voltage is increased, and the instrument automatically triggers the impulse discharge, with three discharge interval options: 3 seconds, 6 seconds, and 9 seconds.

11. Single Button: This button is active when the mode selection is in the Single function.

12. Start Button: In the zero position, pressing the start button starts the high voltage, and the high voltage indicator lights up. In the non-zero position, the high voltage indicator does not light up.

13. Stop Button: Press this button to cut off the high-voltage output when the test is complete or an abnormality occurs. The remaining high voltage will also be automatically discharged.

14. Emergency Stop Button: Press this button to cut off the high-voltage output in case of an emergency.

15. Overheat Protection (OTP): This light illuminates and an alarm sounds when the instrument temperature is too high.

16. Voltage Control Knob: The zero-position light illuminates when this knob is in the zero position, indicating that high voltage can be started. Voltage can only be increased using the voltage control knob after high voltage is started.

17. Overcurrent Protection Switch (OCP): Pressing this button indicates that the overcurrent protection function is activated; releasing it indicates that the instrument has triggered overcurrent protection.
 

1. Voltage Select Mode: This button has three voltage level modes: 8kV, 16kV, and 32kV. Please rotate it to the appropriate position before powering on. (Pull, rotate, press)

Side panel


1. Power Socket (220V 50Hz): Power supply for the instrument, AC220V connection port;

2. Fuse Holder: Fuse holder for the AC220V power supply system;

3. Signal Connector: Uses a dual-Q cable to connect the instrument to the cable fault tester for flashover waveform acquisition. Effective only during high-voltage flashover.

4. Grounding Terminal (Auxiliary Grounding Terminal): When the input power socket ground wire is not connected to earth or is unreliably grounded, an auxiliary ground wire must be connected to the ground to form a detection grounding loop.



Back panel






















1. Sampling ground: The negative end of the pulse energy storage capacitor has a high voltage and must be reliably grounded. It is used for sampling when sampling waveforms under high-voltage flashover conditions of the cable fault tester. (Reliable grounding is still required for non-high-voltage flashover sampling).
2. High-voltage ground: Also known as the high-voltage tail, it must be reliably grounded to prevent high-voltage leakage and discharge. Poor contact may result in failure to boost voltage, high-voltage breakdown and damage to internal devices of the instrument, and internal leakage or discharge of the instrument causing safety accidents.
3. High-voltage output (HV OUT): Dedicated DC high-voltage output terminal.
