Testing Solutions of the Protection Systems Provided with Delay Maximum Current Relays
Journal Title: Carpathian Journal of Electrical Engineering - Year 2017, Vol 11, Issue 1
Abstract
Relay protection is one of the main forms of automation control of electro energy systems, having as primary aims fault detection and disconnection of the faulty element in order to avoid the extent of damages and the as fast as possible recovery to the normal operation regime for the rest of the system. Faults that occur in the electro energy system can be classified considering on one hand their causes and on the other their types, but in the vast majority of cases the causes of the faults are combined. Further, considering their nature, faults are classified in faults due to the insulation’s damage, in faults due to the destruction of the integrity of the circuits and faults determined by interruptions. With respect to their nature, faults are short circuits, earthing faults and phases interruptions. At the same time, considering their type, faults are divided in transversal and longitudinal ones. The paper presents a testing solution of the delayed maximal current relays using a T3000 ISA Test measuring equipment.
