Simulation of electrical networks and relay protection, analysis of the protection.
Overcurrent protection – protection used on almost all types of electrical equipment. This protection responds to an increase in the current flowing on the protected equipment.
A differential relay is used in the implementation of the basic protections of various equipment: generators, transformers, power lines, etc. The use of a relay with a braking characteristic prevents the non-selective action of the protection.
Inverse time delays are used to implement protections, the response time of which depends on the value of the input quantity. The use of inverse time delays can reduce the trip time of close short circuits with high currents, while ensuring selectivity of protection.
