How not to overspecify high voltage CTs and VTs | EEP· Measure #9 – For class PS CTs, the value of the knee point voltage V K is specified as:. V K ≥ K × I × (R CT + 2R L) × V. where: K = constant governed by system parameters and relay characteristics (a typical value being 40),; I = rated relay current (1 or 5 A), (for delta connected CTs, this value is obtained by multiplying 13 to CT secondary current),; R CT = ac resistance of ...
