YSB2679 Grounding Resistance Tester

1productIntroduction

YSB2679Grounding resistance testerIt is used to measure the grounding resistance inside electrical equipment, which reflects the various parts of the electrical equipmentoutsideThe (contact) resistance between the conductive part and the main grounding terminal of the electrical equipment. In order to eliminate the influence of contact resistance on the test, the grounding resistance tester adopts the four terminal measurement method, which adds current between the exposed conductive part of the tested electrical device and the main grounding terminal, and then measures the voltage at these two ends to calculate its resistance value.

YSB2679Grounding resistance testerin accordance withGB﹑IEC﹑ISO﹑BS﹑UL﹑JISDesigned according to international and domestic safety standards, the indicator of grounding resistance is one of the important indicators for measuring the safety performance of various electrical equipment. It is under high current(25Aor10A)In this case, measuring the resistance of the grounding circuit is also a test of the grounding circuit's ability to withstand high currents, in order to avoid insulation performance issuesdrop(Or damage) to personal injury. This tester is developed and produced to meet the above requirements and provide high-performance testing instruments for production workshops and experimental departments. This instrument has low requirements for power supply voltage, high measurement accuracy, fast speed, and easy use, making it particularly suitable for use in high demand laboratories and automatic detection lines. The open circuit alarm selection function (i.e. open circuit alarm) can easily determine whether the instrument is working in a normal testing state, and users can choose whether to use this function according to their actual needs. This instrument adopts a three and a half digit display, which is convenient for reading. It adopts an optimized design, and the whole machine has high reliability and stability.
