Acrel AHLC-LTA series of DC leakage current sensors are developed using the principle of magnetic modulation and zero magnetic flux. Electrical isolation and perforation measurement with low current have good accuracy, linearity and stability. It is widely used in DC transmission, DC screen, storage detection, power supply, photovoltaic, wind power generation, medical equipment, communication base station and other industries.
