Overview
- ETCR2000X Clamp Earth Resistance Tester is a major breakthrough in traditional grounding resistance measurement technology, widely used in power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment grounding resistance measurement.
- ETCR2000X Clamp Earth Resistance Tester is safe, fast and easy to use, without disconnecting the grounding lead line and auxiliary grounding pole when measuring the grounding system with a loop.
- The ETCR2000X Clamp Earth Resistance Tester can measure the ground fault that cannot be measured by traditional methods, and can be applied to the occasions that cannot be measured by traditional methods, because the ETCR series clamp ground resistance meter measures the combined value of the grounding resistance and the grounding lead resistance.
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.
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.
From the measuring principle, ETCR series Meter can only measure the loop resistance, the single-point grounding is not measured. However, users are able to use a testing line very near to the earth electrode of the grounding system to artificially create a loop for testing. For details, please read user manuals.
