MI2124接地電阻測試儀@MI2124%

近幾年來，國內很多用戶采用鉗式地阻儀測量接地電阻，但測試結果與實際相差很大。因為鉗式地阻儀測量的是回路電阻，在某些特殊請下測量結果可能
接近真實值，而大多數情況下測量的結果并不正確。比如對于一根桿塔有四個接地引下線的情況，采用鉗式地阻儀測試結果是四根接地引下線構成的回路電
阻，根本不是接地電阻。廣大電力工作者雖然知道測試結果并不正確，但因為此法不需要打開接地線，現場測試很方便所以只好采用今天一種嶄新的接地電
阻測試方法--選擇電極法誕生了。該方法可以準確測量接地電阻，不需要打開接地線，同時具有很傳統打地樁法準確的優點和鉗式法方便的優點，對于接地
測試來說選擇電極法具有跨時代的意義。具有選擇電極法測試功能的接地電阻測試儀--MI2124接地電阻測試儀

MI2124 ground resistance tester @MI2124%

In recent years, many domestic users with pliers type ground resistancemeasurement of grounding resistance, but the test results and the actualdifference. Because the measuring clamp type ground resistance meteris the loop resistance, in some special please measurement results may

Close to the true value, and in most cases the measurement results is not correct. For example, there are four grounding downlead situation fora tower, the clamp to test resistance instrument is four grounding downlead constitute the loop.

Resistance, no grounding resistance. The majority of electricity workersalthough know the test results is not correct, but because this method does not need to open ground, field test is easy so I had to use a newground today

Resistance test methods -- selective electrode method was born. The method can accurately measure the grounding resistance, does not need to turn on the ground, and has the advantages of advantages andclamp method accurate very traditional ground pile method convenient,for grounding

Test of selective electrode method which is of epoch-making significance.A selection test function electrode grounding resistance meter --MI2124 ground resistance tester
