General Info / Application

GDYZ-30D from HV Hipot Electric is composed of two parts: Control Unit and HV Unit.
It is designed to do breakdown test for lightning arresters with series gaps and TBP over-voltage protectors, which has been widely used in power systems of 35kV and below.

Features
320*240mm LCD screen, and high speed thermal printer.
User-friendly design, intelligent operation, and good anti-interference performance.
Two optional modes for testing: manual and automatic.
Real-time display voltage on high voltage side and current on low voltage side.
Over-voltage and over-current protection, with sound and light alarms.
Zero protection. Test will start only after the instrument has been reset to zero.
Self-diagnostics function, easy to detect errors and solve problems.
Extended functions available, such as remote communication, and calibration interface for voltage divider.
