What is the distance between the earth resistance tester and the two earth post?
Product characteristics:1, suitable for any ground site, non ground touch type measurement and auxiliary pile dual measurement method, without multi-point or single point grounding, can be tested normally;2 、 can be measured on-line, the use of power equipment, without the need to disconnect the ground and equipment. Can also be measured;3, anti-interference ability, self-produced high-frequency currents, thereby filtering the 50Hz, 100Hz and other harmonic interference current, even in the 500KV substation environmentIt can also be measured accurately;
The double jaw grounding resistance tester is suitable for testing the grounding resistance of grounding devices of various equipments and buildings. The soil resistivity under various conditions can also be measured. In addition to the traditional function of measuring the grounding resistance of the earth electrode, the instrument has the unique function of non auxiliary pole measurement, and has changed the traditional measuring principle and means of the test grounding resistance. The utility model realizes the on-line measurement without the need to hit the auxiliary earth pole without isolating the grounding body from the equipment. The machine has intelligent measurement function, can store and browse the measurement results, and show the use of Chinese characters.
Automatic display of soil resistivity without tedious calculation;5 、 built in large capacity memory, can store 100 sets of measurement data;6 、 configure charger and rechargeable battery, power saving design, automatic power-off after exceeding specified time;7 、 adopt the four wire method to measure the grounding resistance below 0.7, and it can also be measured accurately.
