Distance Relay Model

Relay contact input and output status or any data communication in protection and control systems can be monitored before and after any type of fault. Several tabular reports and plots are also provided to show the status of relay contact inputs and outputs in case of single or sliding faults.

Using ETAP StarZ, users can not only evaluate the characteristic settings and relay coordination, but also can evaluate analog and digital interfaces and their related settings, user logic, data communication between relays, local and remote backup protection, breaker failure and more.

Different characteristics from various relays can be plotted at the same time and referenced to a common point for the purpose of setting validation and relay coordination. Measured fault impedance by a relay element for a single fault or sliding faults with different fault resistances can be plotted along with relay characteristics. Users can evaluate the performance of single or multiple relays for various fault locations along the selected line and various fault resistances in one click.
