The requirements for separation between ICT cables and power cables depend upon the electromagnetic immunity of the ICT cable, the construction of the power cable, the quantity of, and type of electrical circuits and the presence of dividers etc. We studied and reviewed the regulations and standards relevant for requirements of this separation in domestic and foreign. And then we would like to suggest the method of separation calculation between ICT and power cabling taking the EMC into consideration.

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.
