Product Description

XHEP701A Different frequency ground resistance tester

The digital large-scale ground grid ground resistance tester, also known as the power frequency ground resistance tester, ground resistance meter, etc., is a common instrument for testing and measuring ground resistance. It adopts a new variable frequency AC power supply, dual-frequency measurement technology, super large touch 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, contact voltage, current phase angle and other parameters. It is suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc., and meets the standards of power substations and lightning protection device detection instruments. The instrument test is accurate, fast, simple, stable and reliable. The maximum open circuit voltage output of this tester can reach 400V, and the maximum short-circuit current can reach 5A. Microprocessor control and automatic dual-frequency technology can accurately measure and calculate the ground impedance value under 50Hz power frequency under strong interference, and the large screen display is clear at a glance. 100 sets of data can be stored at the same time, and the resistance measurement range is: 0.030Ω~2000Ω. The measured data can be printed out through a thermal printer. The digital large-scale ground grid ground resistance tester consists of a host, test wire, ground rod, etc., and has the functions of reading, reviewing, saving, and printing historical data.
