III. Instrument Operation:

Firstly, familiarize yourself with the panel structure of the instrument and understand the functional features of each switch and knob.

      It is particularly important to note that:

“Impact High Pressure Selection”——Preselecting the output for high-voltage surge. The voltage value indicated by the knob represents the approximate voltage at which the internal discharge gap breaks down (i.e., the surge high voltage applied to the cable under test). The breakdown voltage for the large discharge gap is35KVPlease provide the Chinese content to be translated.“Impact High Pressure Selection”Knob placed“0Discharge”At this point, the discharge ball gap closes and the stored energy capacitors and the residual voltage on the tested cable are automatically discharged (automatic discharge).

“Voltage Regulation”——After the high-voltage start-up, rotate this potentiometer clockwise.“High-Pressure Indicator”The meter reads the actual DC voltage applied across the discharge gap.

“High-voltage Start-up”——High-voltage start button, only when“Voltage Regulation”Fully rotate the knob to the left and then press the button to activate high voltage.“Voltage Regulation”The ability to regulate pressure is essential.

“No Chinese content provided.”Electric Meter——During the high-voltage impulse test, this meter indicates a constant current charging current for the internal energy storage capacitor.

“High-Pressure Indicator”Electric meter——Real-time indication of the direct current high voltage added to both ends of the discharge gap and the breakdown high voltage of the gap.

“Protect Instructions”Lamp——Overload indicator for discharge circuit. The light will flash when the tested circuit is punctured, causing an overload of the high-voltage output. Power off and restart required.

“Impulse High Voltage Output”Plug——This high-voltage socket can directly output the DC high voltage set by the instrument and add it to the fault phase terminal of the tested cable.

“System Grounding”——Prior to conducting DC withstand voltage tests and impulse high-voltage tests, this equipment must be reliably connected to the grounding rod and to the grounding wire of the test cable, in a systematic manner.

Operation Steps:

1Proper wiring and secure grounding are essential for safety.

2Pursuant to the testing requirements, first...“Impact High Pressure Selection”Adjust to the required voltage range, then“Voltage Regulation“Turn the knob to the left to the smallest position (otherwise, it cannot be activated).

3Power on the switch, press“High-voltage Start”Turn key clockwise slowly“Voltage Regulation“Turn the knob until the discharge gap breaks down and discharges. If the fault point is not fully pierced, first turn off the power.“Impact High Pressure Selection”Adjust the voltage to a higher level, then turn on the power switch, restart the high voltage, and continue to increase the voltage until the fault point is fully punctured. Whether the fault point has been punctured can be judged from the waveform obtained by the cable impulse flash method (refer to the cable fault tester's instruction manual). The discharge frequency can be adjusted by...“Voltage Regulation”Knob for control. Continue to turn clockwise.“Voltage Regulation”Knobs, increase discharge frequency, accelerate discharge rate; conversely, slow down the discharge rate. Generally, the discharge rate is controlled at2～3In a jiffy. Adjust.“Voltage Regulation”The dial does not alter the breakdown voltage of the discharge gap; it only changes the discharge rate.

4At shutdown, first adjust the voltage to low, then press“High-voltage Start”Cut the high-voltage power supply.“Impact High Pressure Selection”Adjust to“0(Discharge)”After fully discharging the internal energy storage capacitors and the cable under test, ensure that the residual voltage has been fully released before shutting down.“Power Switch”Further disassemble the connecting lines.
