Course Objective Isolation coordination takes an important place at electric facilities design and management. One of the main reasons of the occurred problems at energy transmission and distribution systems is discharging cases like vault and puncture, which occurs at isolation material.
Course Content Basic definitions. Over voltage at high voltage facilities: Indoor/Outdoor over voltage. Vault and endurance voltage. Reactions of transmission lines to lightning pulses. Scale electricity facilities based on shunt over voltage. Protection tools for over voltage Surge arresters, specifications, types and selection of Surge arresters. Isolation coordination at high voltage electric facilities
