Overview

• ETCR2000A Clamp Earth Resistance 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.
• ETCR2000A Clamp Grounding Resistance Tester, in the measurement of a grounding system with loop, does not require breaking down the groundingdown lead, and no need theauxiliary grounding electrode. It is safe, fast and simple in use.
• ETCR2000A clamp grounding resistance meter can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the ETCR series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance. .
• In addition,the C type Clamp Grounding Resistance Tester is also able to measure the leakage current and the neutral current in the grounding system

Field Application

The application of machine room earth resistance measurement

• The machine room of telecommunication system normally in the upper deck of the building. It is hard to use the meg-ohm meter to measure. However, ETCR Clamp meters are very convenient to test.

The application of substation earth resistance measurement

• ETCR series clamp meter can use to test the situation of contact and connect of circuit. With the help of one test line, it can be used to test the connect situation of equipment in station and the grounding system. Single point grounding measurement is allowed for the measurement of grounding resis.

The application of building lightning protection grounding system measurement

• If the earth poles of the building are independent of each other, the earth resistance can be measured by clamp to testing any of the earth poles, and the earth resistance can also be measured by clamp the building roof lightning arrester.When the measured value is less than the allowable value, the earth electrode is qualified.If the measurement value of the clamp meter is larger than the allowable value, please use ingle earth point method to measurement.
