Clamp on earth ground tester
digital earth resistance
YH302 is a 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. Therefore, setting safeguard grounding to prevent person and facility is discharged), 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 vertical grounding pole and horizontal grounding pole used for power 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.
Features
Test Voltage have 20v/48v Provide choice
*2 pole resistance measurement.
*3 pole & 4 pole earth resistance mearurement.
*4 pole soil resistivity testing.
*Current Clamp selection method is used to measuring earth resistance without breaking grounding connection.
*Double clamp without auxiliary electrode is used to fast measuring grounding resistance.
*Automatic frequency control (AFC) is automatically identified interference frequency and then selected the proper measurement frequency, so that reduced the affect of interference voltage.
*Automatically measuring the interference voltage and the leakage current. The limited value will be alarmed.
*Auto power off
*Clock display
*Double battery power supply and low battery indication.
*Data storage function and uploading to PC by USB 2.0 interface.
