Selection Of Grounding Resistance Tester

Howto select the type ofgrounding resistance tester? GDZX introduce the selection method of grounding resistance tester, please read the full text.

Grounding resistance tester is a common instrument for measuring grounding resistance, and it is also an indispensable tool for electrical safety inspection and completion acceptance of grounding engineering. With the rapid development of computer technology, ground resistance tester has penetrated a lot of micro processor technology, and its measurement function, content and accuracy are incomparable. The new clamp method is used in the grounding resistance tester, which can be directly measured online without piling and setting out. Controlled by microprocessor, it can automatically detect the connection status of each interface and the interference voltage and frequency of grounding grid, and has the unique functions of numerical value keeping and intelligent prompt.

Selection of grounding resistance tester:

1. At present, intelligent grounding resistance instrument has powerful functions, such asBY2571 digital grounding resistance tester, which can deal with various complex situations on site, effectively eliminate interference, automatically track suitable test strip and ground parts, and prompt intelligent prompt immediately when there are various problems.

2. The single jaw grounding resistance meter is mainly used to check the multi electrode grounding network connected above the ground and inquire the grounding conditions of each grounding electrode through the loop grounding resistance, but it can not replace the power frequency grounding resistance measurement of the whole network. ETCR2000 clamp type grounding resistance tester is also a popular grounding resistance tester at present. The instrument is small in size and easy to operate. Therefore, it is an ideal grounding resistance meter to inspect the grounding device in rainy season, mid year and end of the year.

3. If the measurement accuracy is higher, and it is convenient and easy, theZXET3006 double jaw grounding resistance testercan be used to measure the grounding resistance of grounding devices such as wire tower, microwave tower, lightning rod, and auxiliary devices (faucet, water pipe device) with good grounding conditions. ZXET3006 double jaw grounding resistance tester perfectly combines the characteristics of traditional voltammetry measurement and the new technology principle of clamp method, and then uses new computer control technology, which has become the leading intelligent grounding resistance measuring instrument. It has the characteristics of high precision, complete functions and easy operation. It can be widely used in grounding resistance measurement of power telecommunication system, building, airport, railway, oil tank, lightning protection device, high voltage tower, etc. At present, it has been configured in the domestic post and telecommunications, electric power, aviation and other industries.

4. For large-scale system grounding, network grounding and soil resistivity test, it is better to selectZXDW-3A large grounding grid grounding resistance tester. Three wire and four wire measurement method are used to ensure the repeatability and stability of ground resistance measurement value due to the unique function of the instrument. Moreover, the measurement accuracy of ZXDW-3A large grounding grid grounding resistance tester is as high as 3%, and its test current is less than 3A. At the same time, it also has a strong anti-interference ability, so it can be measured without power failure.
