INTRODUCTION

TesterMeter-ETCR 2000C 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.

TesterMeter-ETCR 2000C Clamp Grounding Resistance Tester, in the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use.

TesterMeter-ETCR 2000C 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 TesterMeter-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.

APPLICATION

Measurement Principle


  • Measure the loop resistance

(Base on the formula: R=E/I)

  • Measure the grounding loop resistance system

(R1 is the measured earth resistance;

R0 is the equivalent resistance of the grounding resistor in parallel)


Measurement Method

  • Two earth point measurement method


The RA is the measured grounding object, connecting RA

and RB (which is the nearly grounding object like as water

pipe or building) with one wire, the tester will test and indicate the concatenation resistance value of the ground

resistance and the test line resistance.

RT=RA+RB+RL

(RT is the tested value, RL is the test line resistance value)


  • Three earth point measurement method


       (1).Connect the RA and RB with a test line; use the Meter to

get the first reading R1;

(2).Connect the RB and RC with a test line; use the Meter to

get the first reading R3;

(3).Connect the RA and RC with a test line; use the Meter to

get the first reading R2.

In the above three steps, the reading measured in each step is the value of the two series grounding resistance.

In this way, we can easily calculate the value of each grounding resistance,According to the reading value of R1,R2,R3:

R1=RA+RB; R2=RA+RC; R3=RB+RC

Then: RA=(R1+R2-R3)/2

As the reference points, the grounding resistance values of the other two grounding bodies

RB and RC are:

RB=R1-RA; RC=R2-RA

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, TesterMeter-ETCR Clamp meters are very convenient to test.


  • The application of substation earth resistance measurement


TesterMeter-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 resistance.


  • 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.
