Product Overview & Application Scenarios
Product Overview
The Digital Partial Discharge Tester (Model HM512) is a multifunctional, high - precision detection device that integrates partial discharge (PD) measurement, fault location, and online monitoring. Equipped with advanced electronic technology and a computer processing system, it supports dual - channel synchronous acquisition and features a TFT touch screen display. With high sensitivity, wide measurement range, and intelligent analysis capabilities, it is ideal for evaluating and diagnosing the insulation performance of high - voltage electrical equipment.
Application Scenarios
Partial Discharge Measurement: Factory testing and on - site inspection of high - voltage cables, transformers, GIS (Gas - Insulated Switchgear), etc.
Fault Location: Precise identification of internal PD fault points in power equipment (requires optional location module).
Online Monitoring: Long - term continuous PD monitoring for large power transformers, generators, etc. (requires optional online monitoring module).
