SI85-271 Price
The capacitor C5 is used to compensate for any phase shift between the voltage sense and current sense input caused by the current transformer. As an example to compensate for a phase shift of 0.18 degrees the capacitor value is calculated as follows: C = 1/(2 x x Mains frequency x R5xtan (Phase shift angle C = 1/(2 x x 50HzxlMQ x tan (0.18degrees C = 1.0131JF
