Transformer

LSY3-10/130 three-phase integrated current transformer is suitable to be installed on the three-phase bushing of ring network switch cabinet and main column. It is used for the measurement and protection of three-phase current and zero sequence current, and can also be used for the measurement and protection of zero sequence current of multiple cables circuits. The iron core and secondary winding of this series of current transformers are vacuum-cast with high quality epoxy resin in a flame-retardant plastic housing, which is moisture-proof, stable and maintenance-free.

SEN-LSSZ 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 is obtained by cable puncture for 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. The tie-up installation is convenient for construction, especially for large current measurement. Due to its flexible characteristics, it can be used to measurement the conductor current with large size ((such as conductor diameter ≥3M) or irregular shape or very narrow space between conductor ( for example, when the traditional clamp current probe can not be measured, the flexible Rogowski coil current sensor can be easy measured) . The joint has temporary type and long-term type, the former is plug type, used for portable instrument or temporary current measurement , used for long-term current measurement online. Easy to install without damaging the conductor.

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.
