The methodology of the voltage measurement CTs is the direct contact to the measured conductor. The voltage flow through the circuit of high impedance (ex.110K ohm) creates current loop in the CT’s primary side and the same current generates in CT’s secondary so as to induce the voltage-out across the burden. Taehwatrans’ specialty is the perfect isolation between primary and secondary winding, and excellent performance in reading voltage with no delay in phase displacement.
The application could be the voltage measurement in the field of sub-station, distribution channel which requires the high accuracy and no phase delay. Taehwatrans offers varieties of measurement experience and how to do for best usage with several types of CT’s manufacturing method.
