About this document
Understanding Transformer Neutral Earthing by kittiey is a document available to read on EtoBox.
The document discusses system neutral earthing. It explains that earthing provides a low impedance path for protective schemes, ensures safety of living beings near substations, and maintains system voltages within limits during faults. An effectively grounded system has a ratio of zero sequence reactance to positive sequence reactance less than 3 and a ratio of zero sequence resistance to positive sequence reactance less than 1. This allows surge arresters to be used at less than line-to-line voltage ratin
