Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions [PDF]
, 2014 Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current.

IET Generation, Transmission & Distribution, 2023 The algorithms of the present generation of practical differential relays are based on two methods. The first method is based on the ratio of the harmonic content of the differential current, and the second one is based on the length of the time interval
