Product Description

I. General Information  
 
GDZG-300 series of DC Hipot Test Set is used for testing DC high voltage for zinc oxide arrester, magnetic blowing arrester, power cables, generators, transformers, switches and other equipments. It is suitable for electric power branch, power department of factories, scientific research units, railway, chemical industry, and power plants.
 

II. Features

• With Medium Frequency Voltage-multiplying circuit and PWM pulse width modulation technology, big power IGBT components.
• Higher voltage stability, smaller ripple coefficient.
• 75% VDC 1mA function button, convenient for Zinc Oxide arrester test.The accuracy is ±1% of the reading±0.2kV.
• High precision, exact measure, figure display, with good anti-interference function.
• High stabilization of voltage regulation and regulates voltage smoothly from zero.
• With protection functions of over-voltage, over-current, returning-zero, ground.
• Negative polarity output, zero-start, continuous adjustment.
• Number dial switch for over-voltage set function, which can display voltage value clearly.
• △-Y shoring design for HV booster, which is portable to carry.
