Lowering the Limits for Earth-Fault Detection
... The presence of harmonic-frequency voltages (integer multiples of the fundamental frequency) in an electrical system cause harmonic-frequency currents that can affect earth-fault detection and minimum trip set points. Harmonics can be the result of the use of adjustable-speed drives (ASD) and solid- ...
