Thanks. If you ever want to make a video covering the details of a 87 differential relay, I'd watch the heck out of it.
i just got hired to be a technician at a old hydroelectric powerhouse built in the 20s and we have a bunch of these old GE relays. thank you for the explanation. i’ll be checking for more videos on these old components.
Great explanation and will presented. Thank you for making the world a better safer place.
What is with the .2 or 2 amp tap selection?
That is for the seal-in unit. It is based off of how much expected current will be going through the trip circuit.
Good one.. u need to do a video of how to calibrate it
Read the manual.
.2 if it trips an auxiliary device, 2 if it trips a breaker directly.
