XL Series Active Zero Flux Leakage Current Sensor

With the development of high-voltage power equipment insulation monitoring technology, micro-current (mA, micro-amp level) sensors are more and more widely used, while single-turn feed-through micro-current sensors have no effect on equipment wiring due to their primary and secondary isolation. It has become the first choice for sensors for online monitoring of high-voltage equipment insulation. For this kind of current sensor, it is required to have high accuracy, good anti-electromagnetic interference capability and long-term stability. The traditional passive sensor cannot guarantee the accuracy and stability of the phase transformation error, and it is difficult to meet the requirements. The micro-current sensor using active zero-flux technology has the above excellent performance, and can accurately measure the leakage current of high-voltage equipment such as transformers, current transformers, voltage transformers, coupling capacitors, and arresters.
