Advanced HV Earthing System for Smart Substations

Advanced power system uses smart communication network for advance operation. Grounding is an imperative component to ensure safety and operation acquiescence of the network are always maintained. Traditional earthing system design reflects high cost on implementation, testing and maintenance. Advanced smart earthing system is required to keep up with the advancement in the power system industries. The paper proposes the design diagram for smart earthing system where it employs all available sources to ensure advance compliance with minimum cost. Case study to support the theoretical analysis is included.
