DR-700 Portable Partial Discharge Detector: Importance in Power Equipment
Introduction
The health status of power equipment directly affects the safe and stable operation of the power system. Partial Discharge (PD) is one of the important indicators of insulation aging and damage in power equipment. As an advanced detection tool, the DR-700 portable partial discharge detector can inspect and locate power equipment without power outage, promptly identifying potential partial discharge issues, thereby effectively preventing the occurrence of faults.
Product Overview
The DR-700 portable partial discharge detector is a portable device that uses advanced sensor technology to detect partial discharge phenomena inside power equipment. It can be used for partial discharge detection and location in power equipment such as high-voltage cable terminations, insulators, substation open equipment, dry-type transformers, and main transformer bushings.
Main Features
