Low Voltage Extended Range Current Transformers
Ritz has long been regarded as the industry leader in providing cutting-edge metering accuracy performance for instrument transformers. In the 1990’s, Ritz introduced the Medium-Voltage Extended-Range Current Transformer (MV ERCT). This technology is now available in the Ritz Low-Voltage CT offering for utility metering applications.
The Ritz ERCT design offers 0.15% accuracy performance from 1% nominal current up to the rating factor. This performance surpasses all of the metering accuracy classes defined under IEEE and CSA.
