Current Sensor

Wireless passive current temperature sensor is to realize the needs of intelligent and automatic low-voltage distribution network, comprehensive data acquisition and monitoring is necessary. Through real-time online monitoring of the temperature, current and voltage of cables and bus bars, early hidden dangers can be obtained to ensure the safety of users. The passive composite sensor uses the electromagnetic energy around the transmission line to obtain electric energy, online monitoring the temperature and current of the cable, combined with wireless communication, to complete fast and accurate online measurement and save the shackles of the cable, and realize the function of wireless suitable for on-line monitoring of temperature and current transmission conductor in low voltage switch gear. The sensor is not in direct contact with the surface of the electrical equipment, and its built-in analog temperature sensor senses the ambient temperature of the contact surface and gets the corresponding voltage signal. According to the relationship between the voltage signal and no induction, the surface temperature of the live equipment can be determined. Non direct contact, electric field induction is used to detect whether the line is charged,and to detect whether the line is charged when there is no load and no current passing through.

The high frequency current sensor is suitable for when partial discharge occurs inside the cable, the high frequency current will propagate to the ground along the ground wire. A sensor is installed on the ground cable to detect high-frequency current signals for local discharge detection. The sensor uses Rothschild coil operation mode, which surrounds multiple coils of conductive coil on a ring magnetic material. The high frequency alternating electromagnetic field caused by high frequency current passing through the center of the magnetic core will generate induced voltage on the coil. There is no electrical connection between the measurement loop of the sensor and the measured current, which is a non-invasive detection method ,and the equipment under test does not need to be shut down.
