Earth screen is one of the essential devices for the safety of human being and electric equipments. Erath resistance is the major factor for determining the function of the earth screen. DZC earth screen resistance test equipment is designed to measure the resistance of earth screen. Power frequency large current injection is applied to measure earth resistance, which ensures test accuracy.
Measure the resistance of earth screen
50Hz pure power frequency enhances test result
No-load tap changer enables variation of test voltage injected to the ground
Output current of over 30A (generally 40A -60A) enhances test accuracy
Able to connect voltmeter and ampere meter, easing reading of voltage and current value
It can also be used as a power supply for measuring parameters of lines
Output current: 20A，40A，50A，60A，80A，100A optional at 0.5kV
Output current: 10A，20A，25A，30A，40A，50A optional at 1KV
