What is Current and Potential Transformers Overview about?
Current and potential transformers are used to isolate protective relays from high voltages on power systems and reduce current and voltage levels to values suitable for relay operation. Current transformers provide insulation and step down currents, typically to 1-5 amps. Potential transformers also provide insulation and step down voltages, usually to 110 or 120 volts. Accuracy is affected by factors like burden, rating factor, temperature and physical configuration. Tables list specific current and poten
