ES3030 Digital Large Ground Network Tester
ES3030 digital large-scale ground grid grounding resistance tester, also known as power frequency grounding resistance tester, grounding resistance meter, etc., is a common instrument for testing commonly used instruments for measuring grounding resistance. It adopts new frequency conversion AC power supply, dual-frequency measurement technology, large touchable color screen and microprocessor technology to meet the requirements of two-wire, three-wire and four-wire test impedance, and can measure soil resistivity, step voltage, distributed potential, touch voltage , current phase angle and other parameters. It is suitable for telecommunications, electric power, meteorology, computer room, oil field, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. It meets the standards of power substations and lightning protection devices. The instrument test is accurate, fast, simple, stable and reliable.
The ES3030 digital large-scale grounding resistance tester can output a maximum open-circuit voltage of 400V and a maximum short-circuit current of 5A. Microprocessor control and automatic dual-frequency technology can accurately measure and calculate the grounding impedance value under the 50Hz power frequency state under the strong interference state, and the large-screen display is clear at a glance. Store 100 groups of data at the same time, resistance measurement range: 0.000Ω ~ 2000Ω. Measurement data can be printed out via thermal printer.
ES3030 digital large-scale grounding grid grounding resistance tester is composed of host, test wire, grounding rod, etc. It has the functions of reading, viewing, saving, and printing historical data.
