Megger Earth Leakage Clamp Meters are specialised tools designed to measure earth leakage current accurately and safely in electrical circuits.

Earth leakage current, also known as ground fault current, is a small amount of electrical current that unintentionally flows to the ground. This can happen due to faulty insulation, damaged wiring, or other problems with the electrical system. While small amounts of earth leakage current are normal, excessive leakage can be dangerous and can trip Residual Current Devices (RCDs), which are safety devices designed to protect against electric shock.

Megger Earth Leakage Clamp Meters are known for their high accuracy and resolution, even for very small currents. Many Megger models offer True RMS measurement, which means they can accurately measure the effective value of distorted waveforms. This is important because many electrical appliances generate non-sinusoidal waveforms that can be inaccurate when measured with standard averaging methods. Some advances Megger Earth Leakage Clamp Meters also offer additional features such as data logging, peak hold, and auto ranging, which can further enhance their versatility and ease of use.
