Introduction
The English abbreviation for Ground Resistance Tester is: Ground Resistance Tester.
The Ground Resistance Tester is a common instrument used to inspect and measure ground resistance, and it is also an indispensable tool for electrical safety inspections and grounding engineering, completion, and construction. In recent years, due to the rapid development of computer technology, the Ground Resistance Tester has also incorporated a large amount of microprocessor technology, making its measurement functions, content, and accuracy incomparable to those of general instruments. Currently, advanced ground resistance testers can meet all grounding measurement requirements. Using the new clamp method, it allows for direct online measurement without the need for driving stakes or laying wires. A powerful ground resistance tester is controlled by a microprocessor, which can automatically detect the connection status of each interface and the interference voltage and frequency of the grounding grid, and it also has unique functions such as value holding and intelligent prompts.
The clamp ground resistance tester is a major breakthrough in traditional ground resistance measurement technology, widely used in the measurement of ground resistance in power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment. When measuring grounding systems with loops, the clamp ground resistance tester does not require disconnecting the grounding down conductor or auxiliary electrodes, making it safe, fast, and easy to use. The clamp ground resistance tester can measure grounding faults that cannot be measured by traditional methods and can be applied in situations where traditional methods are not feasible, because it measures the combined value of the grounding body resistance and the grounding lead resistance. The clamp ground resistance tester comes in long-jaw and round-jaw types. The long-jaw type is particularly suitable for flat steel grounding applications.
