GOZ-NYH Withstand Voltage Test Equipment
GOZ-NYH withstand voltage test equipment adopts new current relay, so the over-current and zero protection is more accurate, efficient and safe. It can check out those more dangerous concentrated defects so that it has determine function to judge whether electrical equipment can continue to participate in the running to ensure equipment insulation level and avoid the occurrence of insulation accident. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities’ inspection, and issue a withstand voltage test report.
Also called: Power frequency withstand voltage test device, Power frequency withstand voltage control box, Power frequency withstand voltage test table
1. Monitoring feature: high voltage, low power, zero indicator, power indicator, work instructions, timing instructions
2. Protection feature: over-current protection, zero start protection, sound and light alarm
3. Using the new time relay, timer broader (1S ~ 99H)
4. Using the new current relay, more accurate, more reliable, and to ensure personal and equipment safety.
5. Test transformer high voltage coil is cylindrical multi-tower, made of high quality polyester enamel-cover and high-voltage insulation material.
6. Test transformer (5kVA above) is equipped with a movable iron wheel. It has advantages of light weight, small size, easy to move, superior performance.
