HVJF-S PRO Partial Discharge Detector

Ⅰ  Description

Can be widely used in the theater detection of power systems, including the insulation status of high-voltage switchgears, ring network cabinets, voltage / current transformers, transformers (including dry-type transformers), GIS, overhead lines, and cables Detection, to measure the discharge level of electrical equipment through the following indicators:

Partial discharge intensity detection: By measuring the discharge signal within a power frequency period, the intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.

Partial discharge frequency detection: The device measures the discharge signal within a power frequency period, extracts discharge pulses and characterizes the frequency of partial discharges according to the number of discharge pulses.

Ⅵ  Attention

The HVJF-S Pro partial discharge detector is used for the detection and evaluation of the insulation status of high-voltage switchgear, ring network cabinets, transformers, GIS, overhead lines, cable terminals, cable branch boxes and other equipment. There are the following precautions when using this device:

☀ Please use indoors with a temperature of -20 ℃ ～ 50 ℃ and a relative humidity not exceeding 80%;

☀ Please stay away from flammable and explosive dangerous goods;

☀ Please charge the instrument when it is powered on for the first time, and only turn on when the charging indicator is on;

☀ To prevent interference or leakage, please turn off the power switch when charging;

☀ If the liquid and corrosive substances come into contact with the instrument, it should be immediately stopped and shut down, and handled by a professional;

☀ All connectors are imported connectors, and they should be plugged in and out. Do not rotate, shake the connector, or pull the cable forcefully. The plug connector is moderately strong and should be inserted into place when plugged

☀ All mainframes and accessories must not be disassembled. If it is really necessary, it needs to be disassembled by our after-sales service personnel.
