Detection Principle of High Voltage Cable

1. HF detection (Adopts high frequency current transformer)
a. Using coaxial cable to connect BNC interface of high frequency current transformer to BNC interface with electrical signal mark on the host.
(Note: Under this measuring method, no external power supply is needed, no need to turn on the power switch, and only need to open the notebook.)GDPD-505 Partial Discharge Detector cable PD online tester

b. Calibration

The square-wave generator special line passes through the high frequency current transformer, and then the high frequency current transformer BNC interface is connected with the BNC interface of the host machine marked with an electric signal.

(For example, adjust the square wave generator to 100pC step, then display 100pC in the software interface, namely the signal calibration. Specific use method is mentioned in software instruction)

c. HFCT is an open type design, the current transformer is installed on the ground wire of the cable joint, fastening.

(Note: closed gently when fastening. Fasten mode of current transformer adopts magnetic adsorption, may occur at the openings of damage to the transformer due to impact)

2. Acoustic electric detection (Adopts acoustic electric integrated sensor) 

a. Using optical fiber to connect optical signal terminal of acoustic electric integrated sensor with optical signal terminal of the host, open the snap switch, switch step to optical signal terminal.

 (Note: when using optical signals, host needs to power on, press the rocker switch on the right crone of host panel, when the switch indicator light is on, indicates the battery switch is turned on, can start testing.)

b. Put the acoustic electric integrated sensor near the discharge point, using high voltage insulation rod and optical fiber to isolate high voltage, detection under the case of no connection to the cable, the specific detection principle is shown as below:
