RDER2100C+ Multi-Function Clamp Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. In the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use. The tester can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the RDER series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance. The equipment can also measure the leakage current and neutral current of the grounding system.

With the continuous update and expansion of modern technology, the reliability of power system and high voltage equipment also put forward higher requirements, electrical equipment accidents or damage, usually closely related to insulation defects. The large capacity, high voltage, diversified structure and sealing of electrical equipment should be updated and higher requirements. In order to understand the insulation performance of the sample, we must first do absorption ratio and polarization index test to provide safety guarantee for the next leakage, dielectric loss, partial discharge and so on. Our company according to the electric power standardization rules to introduce this type of insulation resistance tester, electricity The equipment carries on the insulation, absorption ratio, polarization index test, provides the early stage accurate judgment for the series insulation test.

RDWR-5A grounding resistance tester is a special instrument for measuring grounding resistance of grounding grid and grounding conduction between grounding points. Using frequency conversion anti-interference technology, Portable Earth Resistance Meter does not need large current measurement, and can measure accurate data of 50 Hz in strong interference environment of substation.
The measurement results are displayed by large screen LCD, and can be printed out by its own micro printer. It simplifies the test operation process, improves the accuracy and accuracy of the test results, and greatly reduces the labor intensity and test cost of the test personnel. The instrument can measure the grounding impedance and resistance at the same time, which can reflect the actual characteristics of the grounding grid
