OR-200 not only can provide a solution on accurately testing the faults of the indirect grounding of the direct current system, non-metal grounding, loop grounding, simultaneous grounding of the anode and cathode, balanced grounding of the anode and cathode and multi-point grounding; it also can accurately display the system voltage, voltage to ground and grounding resistance value. It truly eradicates the fear of trouble in the rear for the operating and testing personnel.

The device is primarily based on the system safety. It carries out the test by the reliable method of low frequency signal according to the highest requirements of the industry standard. It can also carry out a lot of on-site practical applications while not affecting the system.
