Simulation of Inverse Time Delay
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.
Simulation of Time Delays
Time delays are one of the main elements in modeling relay protection. They allow not only to create a delay in the operation of the protection, but, on the contrary, to extend the action of relay protection.
