Product Overview
With the development of insulation monitoring technology for high-voltage power equipment, microcurrent sensors (milliamperes, microamperes) are being used more and more widely. Single-turn through-core microcurrent sensors, with their primary and secondary side isolation and no impact on equipment wiring, have become the preferred choice for sensors used in online insulation monitoring of high-voltage equipment. For this type of current sensor, high accuracy, good electromagnetic interference resistance, and long-term stability are required. Traditional passive sensors cannot guarantee the accuracy and stability of phase transformation errors and are no longer sufficient to meet requirements. Microcurrent sensors utilizing active zero-flux technology possess the aforementioned superior performance, enabling accurate measurement of leakage currents in high-voltage equipment such as transformers, current transformers, voltage transformers, coupling capacitors, and surge arresters.
The TRXLW series passive zero-flux leakage current sensors are microcurrent sensors specifically designed for online insulation monitoring of high-voltage electrical equipment. They feature cores made of materials with high initial permeability, multi-layer metal shielding measures, and compatibility with client-side PCB negative feedback technology circuits. These sensors can automatically compensate for the core, ensuring it operates in an ideal zero-flux state. They are capable of accurately detecting power frequency currents ranging from 100 μA to 700 mA. The phase shift error is no greater than 0.01°, and it exhibits excellent temperature characteristics and electromagnetic interference resistance, fully meeting the accuracy requirements for equipment sampling under complex power plant site interference conditions.
