What is Cos Phi? Cos Phi, or cosine phi, measures the loss of current during transmission. It is the ratio of real power to apparent power, where the current flows out of phase with the voltage, causing reactive power.

To reduce energy loss and use infrastructure more efficiently or utilize capacity limits without expansion, it is interesting to reduce reactive power. Otherwise, additional payment to the grid operator for the transported reactive power may be required.
