Because of the problems of electromagnetic current transformer such as easy saturation, nonlinearity and narrow frequency band, the electronic current transformer is rising gradually. 

Electronic current transformers generally have the advantages of anti-magnetic saturation, low power consumption and wide frequency band. The typical electronic transducers in China are AnyWay inverter voltage transducer, AnyWay inverter current transducer and AnyWay inverter power transducer. Anyway inverter power transducer is a combination of voltage transducer and current transducer.
