Lækstrømmålere

Lækstrømmålere, often translated as leakage current meters, are specialized electrical instruments used to detect and quantify small electrical currents that flow through unintended paths. These unintended paths, or leakage currents, can occur due to insulation breakdown, faulty wiring, or improper grounding in electrical systems and appliances. Detecting and measuring these currents is crucial for safety and operational efficiency.

The primary function of a lækstrømmåler is to identify potential hazards that might not be apparent through conventional circuit testing. A significant leakage current can pose a risk of electric shock to individuals coming into contact with faulty equipment or exposed conductors. Furthermore, these currents can lead to energy waste, premature component failure, and interference with sensitive electronic equipment.

These devices typically employ sensitive current transformers or Hall effect sensors to measure very low AC or DC currents, often in the milliampere or even microampere range. They are commonly used in industrial settings, laboratories, and for the testing of medical equipment, where stringent safety standards are in place. Regular use of lækstrømmålere helps in preventative maintenance, ensuring that electrical systems remain safe and reliable. Their ability to pinpoint even minor deviations from normal operation makes them an indispensable tool for electrical safety professionals.
