lækstrømmåler

A lækstrømmåler, also known as a leakage current meter or ground fault detector, is an instrument used to measure small electrical currents that flow through unintended paths, often to the ground. These currents, known as leakage currents, can arise from insulation degradation, faulty wiring, or other electrical faults. While often imperceptible, significant leakage currents can pose a serious risk of electric shock and can also lead to energy waste.

The primary function of a lækstrømmåler is to detect and quantify these abnormal current flows. They are typically designed to measure currents in the milliampere (mA) or even microampere (µA) range. This allows for early detection of potential problems before they escalate into dangerous situations. Modern lækstrømmålere often incorporate advanced features such as digital displays, data logging capabilities, and sensitivity adjustments.

These devices are commonly employed in a variety of settings, including electrical safety testing of appliances, installations in homes and industrial facilities, and in the maintenance of electrical equipment. By periodically measuring leakage current, it is possible to identify deteriorating insulation or developing faults, enabling proactive maintenance and preventing potential electrical hazards and fires. The accurate measurement provided by a lækstrømmåler is a crucial aspect of ensuring electrical safety and system reliability.
