When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: SEL-351S
have you used sel-351s for SER. I am trying to see the response of the relay to trip low frequency setting point. ie: if I set the low frequency trip at 59.0Hz I got it to trip but I was not sure at what frequency did it trip? (59.1 or 58.99) can I use SER to see the actual trip? if yes how?
thank lots,
Kun

The frequency is reported every 1/4 or 1/16 cycle in the standard event report. You could trigger an event report with an 81D relay word bit.
