Transformer

The new generation of induction CT adopts imported flexible steel strip, which can be adjusted according to the size of the cable in the field construction process, avoiding the problem of difficult installation of traditional induction CT in the installation process.

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.  

This product is the electronic core and shell assembly into one, easy for users to produce and assemble, accelerate the production schedule.

SEN-XSLS-CJ digital Roche coil sensor, used for the electronic measurement of AC Current. The error due to the position of the measured conductor within the aperture and the error due to the proximity of the external conductor are greatly reduced using magnetic shielding techniques. It is a kind of direct alternating current of the main circuit under test into DC4~20mA or RS485 digital signal output accordingly to linear proportional output, fast response, small volume, small power consumption, frequency response width, anti-interference, has the advantages of lighting wave and shock wave protection. 

Flexible Roche coil current sensor is used to measure AC Current, especially high current. Because of its flexible characteristics, it can be used to measure the conductor current with large size (such as conductor diameter ≥3M) or irregular shape or narrow space between conductor ( for example, when the traditional clamp current probe can not measure, the flexible Rogowski coil current sensor can be used to measure conveniently.) The former is plug-in type, which is used for temporary measurement of portable instrument or current, and for on-line long-time measurement of current. It is easy to install without damaging the conductor. It can be equipped with puncture device, temperature sensor device. Suitable for all kinds of busbar installation.
