Abstract

Electricity network requires protection against a variety of disorders such as short circuit phases, phase-zero, phase-earth, lightning strikes, and so on. Fault current should be calculated on each section and each level that allows an interruption to determine the characteristics of the equipment needed to overcome the disorder. When a disturbance occurs on the far side of the channel nearest the relay should operate first with a time shorter than the next relay. The minimum time difference between adjacent breaker about 0-4 seconds. Total interval required depending on the speed and performance of the CB operation relay, normally is 0.5 seconds. With modern CB relay is faster and lower overshoot considered reasonable 0.4 seconds. At low current noise errors are allowed to IEC 60255 is 7.5% of operating time. Protection systems must meet five basic criteria of selectivity, sensitivity, reliability, quickness and non-interference.
