WebCT ratio formula: CT ratio = I (P) / I (s) ————-1. Example: 1000:1. Here 1000 means it is a primary current and 1 means secondary current. Also, we can have rewritten as 1000/1. CT secondary current will be always 1 or 5 to get easy calculation as well as we can create small rating secondary circuits to withstand up to 5 Amps. WebA potential transformer (also known as voltage transformer) is a type of instrument transformer. It is a step-down voltage transformer that reduces the high-level voltage to …
WebCurrent Transformers. Continental Control Systems does not sell CTs rated for use over 600 Vac, so CTs rated for medium-voltage services must be used. Most medium-voltage CTs output 5 amps at their full scale rated current. For example, the secondary winding of a 500:5 ratio CT will output 5 amps when 500 amps flow through the CT’s window ...
