Product Description

Product Description

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 fluxgate theory and the input side 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 cards and used for different current monitoring applications.

Leakage current transformers surround the outlet + and - of the DC circuit. It detects output signals of sensors in circuit branches. If the insulation in circuit branches is 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 differential current passes the leakage current transformer and the output of the sensor is not zero.

Therefore, it is possible to identify the grounded branch in the DC system by detecting output signals from circuit branches. The theory guarantees accurate line identification and prevents the influence of distributed capacitance.

Notes:

1. When the hall sensor is used, in order to obtain better dynamic characteristics and sensitivity, attention must be paid to the coupling between the primary side coil and the secondary side coil. It is recommended to use a single wire and the wire completely fills the hall sensor module wire hole;

2. When the hall sensor is used, the best measurement accuracy can be obtained under the rated input current value. When the measured current is far lower than the rated current To obtain the best accuracy, multiple turns can be used for the primary side, i.e. IPNP = rated ampere-turns. In addition, the temperature of the primary side feeder shall not exceed 80 ºC;

3. The auxiliary power supply of the Hall current sensor shall not exceed ± 20% of the calibrated value when it works normally;

4. Hall current sensor shall not fall from a high place (≥ 1m) during installation and use;

5. It is unable to adjust the zero point and full degree adjustment potentiometer;

6. Auxiliary power supply needs to be configured by itself;

7. The positive and negative poles of the power supply cannot be reversed
