Has anyone ran into the issue below?
I have an elevator controller (by others) that is shutting the elevator down and the controller is given a fault of low leg Amps. I put a Fluke 1735 power logger meter on the line side of the controller to record any events.
This is a 480V 3Ph 3W +G feeder.
My meter shows my voltage for A phase dips to 115V for 17ms and spikes back up to 299V for 9ms. So this event lasted 26ms. This was right around the time I got the call that the elevator shutdown again. Before I start changing the breaker I really would like to make sure that the breaker is the issue. Any thoughts?
Thanks in advance.
