SR750/760 Feeder Management Relays

What is my take-home:

How to correctly install, configure and maintain the SR750 and SR760 Feeder Management Relays. Using computer and the front panel will test the operation of common feeder protective elements through simulation software. Diagnostic tools such as Waveform Capture, and Event Log will be used to troubleshoot simulated faults to gain familiarity with their operation while validating correct settings and relay operation.

Who should attend?

Electrical maintenance team Electrical design engineers

Utility managers on their journey of gaining a better understanding of Distribution protection and the use of SR GE Multilin Feeder protection relays.
