Product Description

GDYZ-30C Over-voltage Protection Test Set Over Voltage Protector
 

General Information

GDYZ-30C Over-voltage protection device is widely used in the power system 35kV and below. It can make AC discharge voltage current and DC 1mA reference voltage test, so as to earlier find dangerous flaw of internal insulation moisture or valve aging.

 

Features

• Using high-strength, high-insulation and wear-resistant hard plastic sealed box, which is sturdy and durable, with good shockproof performance, convenient for on-site handling.
• Directly input 220V main power, suitable for various testing site.
• With HV output switch, after OUT circuit can be connected with high voltage output circuit, which can effectively avoid the output high voltage caused by mis-operation. Once there is high voltage output, it will alarm to remind operator.
• Built-in 32bit high speed processor, with data processing capability.
• LCD display, user-friendly.
• Flexible configuration. The main unit can output DC high voltage directly for testing the gapless 3-phase over-voltage protection device and surge arrester. It also can be equipped with testing transformer for power frequency discharge test with series gap over-voltage protector. A set of instruments can complete test items of common over-voltage protectors.
• Test parameters include AC action voltage test of series gap over-voltage protector and DC voltage 1mA reference voltage test of gapless over-voltage protectors and zinc oxide surge arresters. The data is reliable and accurate.
