Today's demands on power substations are greater than ever before, challenging operators to ensure reliable, non-stop power supply with reduced maintenance and installation costs. In this context, the networking facilities in electric power substations are being redesigned to accommodate the desires of communities, where the high performance communication network should guarantee very strict requirements and comply with the IEC61850-3 and IEEE1613 power standards to prevent the possible power disturbances and outages. Besides, used in power utilities, the networking equipments are subjected to extremes of temperature and humidity, as well as electrical transients from high voltage switching.
