Given the severe nature of earth leaks and the potential repercussions, Power Parameters strongly recommend engaging with industry professionals. Whether you think the earth leak is intentional or not, it’s crucial to control the situation regardless. Power Parameters are the leading suppliers of electrical instrument services and calibration across Australia and are here to explain how does an earth leakage tester work.
What Is Earth Resistance Tester Equipment?
So, what is earth resistance tester equipment? Earth resistance tester equipment allows industry professionals to safely and quickly test the imbalance between neutral and line conductors. Power Parameters have some of the most advanced ground testing technology that has optimal accuracy. Calibration using earth resistance tester equipment ultimately enables specialists to identify and fix current leakage or faulty insulation issues.
Adopting specialist equipment such as an earth leakage clamp meter provides an accurate reading of the earth leakage of entire electrical systems. It also ensures the safest way to measure and identify any issues that may arise. Now that we have learned some more about earth resistance tester equipment let’s get practical. The next section of the article will examine how does an earth leakage tester work.
How Does an Earth Leakage Tester Work?
Now that we have a better understanding of what earth resistance testing is let’s get to the bottom of the question you’re all here to have answered. How does an earth leakage tester work? Earth leaks are tested in two different ways. The first way of testing an earth leakage is to adopt an isolated power system (IPS). An IPS is typically combined with insulation monitoring devices that differentiate the imbalance between neutral and line conductors. The IPS method is a less frequently used method of conducting earth leakage testing.
The second and more common earth leakage testing method is combining an automatic disconnection of the supply (ADS). The ADS is based on residual current devices (RCD) or residual current circuit breakers with overcurrent protection (RCBOs). The RCD and RCBOs monitor and compare the current that flows in between the neutral and in line conductors. The reading from the device will indicate whether there is a currency flow problem and may cause the device itself to trip.
Now that we have explained how an earth leakage tester works, the next section of this article will outline how to check earthing with tester equipment.
How To Check Earthing With Earth Tester
As the nation-wide experts in insulation resistance tester calibration, Power Parameters are experts in understanding how to check earthing with tester equipment. Earth leakage clamp meters measure the imbalance of neutral conductors and line conductors, calculating any system’s earth leakage. An earth tester is a handheld device that clamps around a conductor and provides a current reading. Earth testers can test even the slightest currents so that testers can see where the individual fault is. Professionals will adopt an earth tester to detect where the problem in the circuit lies and fix the issue.
