The ground resistance tester is widely used in ac power distribution system fault current limitation.

These metal resistors are rated for precise electrical resistance and voltage, especially for short periods of time.

Grounding resistance tester is easy to install, requires no maintenance, and has long applicability.

These qualities test several parameters to ensure high standards.

They are widely used in oral, industrial and electrical distribution.

These resistors are designed to work on harmful working conditions and environmental changes.

For the neutral grounding transformer or generator, resistance up to 66 kv provide short duration of fault, such as 10 seconds, 30 seconds. 60 seconds, continuous resistance materials such as stainless steel, usually iron chromium aluminum, cast iron, copper and nickel or nickel chromium alloy.

Temperature rise is normal or according to customer's requirement.

The bright metal grounding resistance is specially designed for specific resistance values and voltages, especially for short periods of time.

The earth resistance tester has the following advantages:

Its resistance is precisely kept at the manufacturing stage of its entire life.

Allow a relatively short period of resistance to use their temperature time constant for a shorter time.

They are easy to install on site.

They require little maintenance and have a longer life.

Do not prevent frost to heat the heating requirement and do not generally prevent condensation heater.
