Rct in current transformer
WebCT ratio means the currant transformation ratio, here the CT contains Single primary current and dual secondary current output. The ratio 100/5 means If the CT primary carries 100 Amps then the output of the CT secondary will be 5 Amps. The dual 5-5 A means the first core used for protection and second core used for metering purpose. http://www.kappaelectricals.com/technical.html
