II. Brief Introduction
ETCR2000
series of Pincer Earth Tester is a major breakthrough in
traditional grounding resistance measurement. It is widely used in the
grounding resistance measurement of the power, telecommunications,
meteorology, oilfield, construction and the industrial and electrical equipment.
ETCR2000
series of Pincer Earth Tester, in the measurement of a
grounding system with loop current, does not require breaking down the
grounding wire, and need no auxiliary electrode. It is safe, fast and simple in
use.
ETCR2000
series of Pincer Earth Tester can measure out the faults
beyond the reach of the traditional methods, and can be applied in the
occasions not in the range of the traditional methods.
ETCR2000
series of
Pincer Earth Tester can measure the integrated value of the grounding body
resistance and the grounding lead resistance.
ETCR2000
series of Pincer Earth Tester is equipped with a long jaw, as
indicated in the figure below.
A long jaw is particularly suitable for the
occasion of grounding with the flat steel.
In addition,
ETCR2000C
Pincer Earth Tester is also able to measure the
leakage current and the neutral current in the grounding system.
