Hubei Tianrui Electronic Co. Ltd products

TR-EVT11-10-type electronic voltage sensor using the principle of resistor divider, epoxy vacuum casting; TR-ECT01-10-type electronic current sensor using LPCT low-power coil principle; electronic voltage or current sensor output as a standard Small signal, without secondary conversion, can be directly input through the A / D conversion secondary equipment. Suitable for 10kV column vacuum circuit breakers, load switches or ring network cabinet.

The magnetic field generated by the primary current IP is balanced with the magnetic field generated by the secondary coil current. HALL device and auxiliary circuit secondary magnetic compensation current, the current accuracy can reflect the primary current.

This product is designed according to National Grid 2017 version of 10KV overhead remote-type fault indicator. Built-in sampling CT, taking CT, electric field measuring shrapnel, sampling CT using Rogowski coil principle, PCB production, high accuracy, good linearity, Good performance. Take power CT core 1J85 material, high permeability, take power, stable performance, and never rust. Structure with anti-vibration, anti-drop, tensile, waterproof features. Users only need to connect the circuit board, battery and capacitor in the shell to form the finished product.
