WebThe actual characteristics of the differential relay cannot currently be modeled in Captor. However, a generic TCC representing any adjustable pickup and delay can be used instead to represent the trip time for the fault. Based on the above, two protective devices are needed to be inserted into the electrical network to define the protected zone. WebIntro Video. Module 01: Introduction to Numerical Relaying.
