Large Ground Grid Tester 5A Step Voltage Distributed Potential Contact Voltage 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 磅Normal0 Application Scenarios: Digital large-scale grounding grounding resistance tester, also known as power frequency grounding resistance tester, grounding resistance meter, etc. are common instruments for testing and measuring common grounding resistance meters.It adopts new variable frequency AC power supply, dual frequency measurement technology, large touch color screen and microprocessor technology to meet the requirements of two-wire, three-wire and four-wire test impedance. It can also measure soil resistivity, step voltage, distribution potential and contact voltage. , current phase angle and other parameters.Applicable to telecommunications, electric power, meteorology, computer room, oil field, power distribution line, iron tower transmission line, gas station, factory grounding grid, lightning rod, etc., in line with the standards of power substation and lightning protection equipment testing instruments. The instrument test is accurate, fast, simple, stable and reliable. Digital large Grounding Resistance Tester maximum open circuit output voltage up to 400V, the maximum short-circuit current up to 5A.The microprocessor control and automatic dual-frequency technology can accurately measure and calculate the grounding impedance value under the 50Hz power frequency state under strong interference state, and the large screen display is clear at a glance.It can store 100 sets of data at the same time, and the resistance measurement range is 0.000Ω～2000Ω. Measurement data can be printed out via a thermal printer.. Digital large Grounding Resistance Tester consists of a host computer, test leads, and grounding rods. It has functions such as reading, reviewing, saving, and printing historical data.
