The ratios between the primary and secondary rated voltages and rated currents are the PT and CT ratios. For example, if the rated primary current/rated secondary current is 500 A/5 A, the CT ratio is 100. The same holds for PT. If not using a PT or CT, each ratio is 1.  For Example:   PT Primary = 66KV, PT Secondary = 110V Therefore select Vrated = 110V.  PTR = 66KV/110V=600 select.  CT Primary=100A, CT Secondary=1A Therefore select Irated = 1A.  CTR = 100A/1A=100 select in meter.[/vc_column_text][/vc_tta_section][vc_tta_section title=What happens w
