Hubei Tianrui Electronic Co. Ltd products

Current transformer used specially for electricity meter. Small, high precision, excellent consistency. Wide measurement range, strong antisaturation. Flexible installation modes, i.e., PCB mode and line connection mode.

This product is used for single-phase, three-phase electronic energy meter energy metering, especially for small current acquisition or non-periodic components of the electronic meter. Micro-transformers for electronic power meters for current sensing.　According to the user`s requirements to design and produce products, the following figure shows the Tianrui Electronics many products more representative of several.
 

Suitable for 10kV column vacuum circuit breakers, load switches or ring network cabinet. 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.

This product is used for three-phase AC motors, power generation equipment, power transmission and distribution equipment, power management, for accurate measurement and protection. Can be used for three-phase AC motors, power generation equipment, power management and other equipment for current monitoring and protection of the transformer.  According to the user`s requirements to design and produce products, the following figure shows the Tianrui Electronics many products more representative of several.

TR21 series of residual （zero sequence） current transformers, designed to collect the remaining （zero sequence） current signal and design. Remaining （zero sequence） current is usually mA level, and must be through the way of the core, the balance of characteristics, interference and linearity higher.  This series of products wide measuring range, rated current range: 10mA ~ 5A, rated secondary current range: 0 ~ 5mA, excellent high permeability magnetic core and advanced production process to ensure its accuracy level, reliability, etc. skills requirement.
