Description

General Information

GDZG-300 series of DC high voltage tester is testing DC high voltage for zinc oxide lighting arrester, magnetic blowing arrester, power cables, generators, transformers, switches and other equipments, which is suitable for electric power branch, power department of factories, scientific research units, railway, chemical industry, power plants.

Features

Use high frequency voltage multiplier circuit, PWM pulse width modulation technology and high power IGBT device .
With large voltage feedback, the output voltage stability is high and the ripple coefficient is ≤ 1%.
Smooth voltage regulation of full range, fine voltage regulation, accuracy is ≤ 0.5%, stability is ≤ 1%, voltage and current error is 1% (reading (±0.2kV), current error ±1 digital.
The boost potentiometer starts from zero.
With 75% UDC1mA function button, convenient for zinc oxide arrester test, accuracy is 1% reading±1%.
Over-voltage protection using the dial code setting, very clear, the error is ±1%.
Double pressure is made of new materials, which is light and sturdy. The exterior is coated with special insulating materials, which have good electrical performance and strong moisture resistance.
Folding feet, large diameter area, good stability.
Integrated design and high-voltage mopping cable are taken out to facilitate on-site testing.
The product meets the technical requirements of DL/T848.1-2004, and has been tested by the electrical equipment quality testing and testing center of the Ministry of Power, and strictly enforces the enterprise standard.
