    Description:


    Advanced earth Resistance Tester YH302

    The YH302 is advanced intelligent Earth Resistance Tester, which is used to measure grounding resistance for grounding pole connected to some conductive part of facility in the power

    distribution unit of power circuit or building structure, for working grounding (the power distribution unit of power circuit is setting some earth electrode for good operating condition),

    for safeguard grounding( if the insulation is damaged, the metal case of electric facility and the construct

    rack of the power distribution unit or electric pole tower may be electrified.

    Therefor, setting safeguard grounding to prevent person and facility from electric damage), for safeguard grounding for the thunder and lightning

    (It is seted for thunderstruck safeguard facility is discharg),for static electricity safeguard grounding (to prevent

    the inflammable oil, natural gas tin and pipe from static electricity danger).

    For grounding pole (It is metal conductor that is buried in the soil and directly in touched with earth), for grounding wire(It is used to connect the ground terminal of electric facility to grounding pole), and for the Grounding Net (It is Large-Size horizontal net grounding unit that is consist of vertial grounding

    pole and horizontal grounding pole used forPower House,Transformer Station.

    The grounding unit has discharge function and Stabilize voltage ) The tester used for the furnish power, transformer station , it's rated AC voltage up to 500KV.
