Product Description

HD9002 High Voltage Switchgear Partial Discharge Tester

Darui Electric recommends for you:

I. Product Overview

    When partial discharge occurs, it generates physical phenomena such as ultrasonic waves, heat, light, and magnetism. Among them, ultrasonic waves propagate outward in the form of spherical waves centered on the sound source.The HD9002 High Voltage Switchgear Partial Discharge Tester detects the existence and location of partial discharge by receiving ultrasonic signals generated by partial discharge, and quickly diagnoses the partial discharge condition combined with real-time displayed images and data. This locator integrates two detection methods: transient earth voltage (TEV) and ultrasonic.

II. Functional Features

● Ultrasonic and TEV partial discharge waveforms are on the same interface as the yellow, green, and red three-level warning values, a domestic first.

●  Using dBmV as the unit, the transient earth voltage (TEV) method is used to detect the magnitude of partial discharge;

● Adopts a color LCD screen for a more intuitive and user-friendly display;

● Adds headphone monitoring function; in ultrasonic mode, real-time monitoring of partial discharge signals can be achieved through headphones;

● The display can show waveforms in real time and store valuable waveforms; test data is automatically stored, facilitating test record review and subsequent data analysis;

● High signal amplification and sensitivity; signal reception range: effective distance 30m;

● Moderate intensity red laser aiming with strong focusing capability, accurate positioning, safe and reliable, simple and practical;

● Detects and locates insulator discharge on towers, creepage of exposed cable heads, and partial discharge of underground cables;

● Detects partial discharge in high voltage switchgear;

● Easy to use, small size, light weight, and portable.
