| Abstract |
In this paper, designing of an earthing system in accordance with international standards with regard to 22.9kV-y multi-grounded neutral system is discussed and confirmed that the consumer's earthing system can be a part of a global earthing system by interconnecting its earthing system with the neutral conductor of 22.9kV-y multi-grounded system. Further, it is proposed that some modification of the earthing system design flowchart given in the international standards are necessary when considering the equipotential bonding, lightning protection, and telecommunications facilities as well as the basic safety requirements. |
