DC leakage Current Sensor
DC leakage current sensor is a measuring module that converts the measured direct current Into the proportional direct current or voltage signal according to the flux gate theory and the mput slde is highly Insulated from the output side. Typical outputs include 4-20mA, DC0-5V and DC0-10V signals. These standard signals can be acquired by various devices sucH as PLC, RTU and DAS card and used for different currentmonitoring applications. Ieakage current transformers surround the outlet + and-of DC circuit. It detects output signals of sensors in circuitbranches. If the insulation in circuit branches ls normal, the current passing the sensor must be equal in the opposite direction. The output signal is zero. If a circuit branch is grounded, the dilferential current passes the leakage current transformer and the output of sensor is not zero. Therefore, It is Possible to idenw the grounded branch in the DC system by detecting output signals from circuit branches. The theory guarantees the accurate line identification and prevents the influence of distributed capacitance.
