Time Overcurrent Relay Time Calculator

[changeabilities]

Hi everyone,
I need to verify some relay testing. I have reports but i need a calculator for trip time because of some relay has Extremely and Short time inverse. Do you have anything to help me about that? Relays are SEL btw.
Thanks

Do you have the TestGuy app on your phone? There is a generic TOC/IDMT calculator on there, not sure if that is helpful to you at all.
