Grounding of Generators through Harmonic Suppressors | Earthing

Harmonic suppressor is an iron-cored reactor and is used in the neutral ground connection of a generator so that third harmonic currents are reduced to safe value. If the third harmonics are not suppressed, they can cause dangerous overheating of grounding resistors of grounding transformers or erroneous operation of ground fault protective gear. The reactor is so designed that its [...]
