Ⅰ General Info / Application

GDYZ-30D from HV Hipot Electric is composed of two parts: Control Unit and HV Unit.It is designed to conduct  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.

Ⅱ 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.
