Product description
This product is used for collection and isolation of voltage signals of relay protection equipment, Instruments and meters below AC 1000V .This product is a current-type voltage transformer. The primary is connected with a resistor in the circuit to convert the voltage into current. After the transformer is used for current conversion ,the secondary output current signal is converted into the required voltage through the sampling resistor.
Main characteristics

Good linearity and excellent consistency

Small size ,PCB installation ,suitable for integrated design ;

Low price ,conductive to cost control

A variety of form factors are available

Application
For voltage ,power and energy monitoring required by power auyomation devices;
