Course Summary – This is Part 3 of a 3 part video series on Protective Device Coordination Analysis. In Part 3, Jim Phillips, P.E. shows how to protect transformers based on ANSI C57 thru fault protection using overcurrent relays. See how motor starting curves are used for motor protection.

Learn how overcurrent relays operate as well as how to determine the amp tap, time dial and instantaneous settings. See how to use relay time current curves. Many examples and problems.

The footage was recorded at the One Week Power Distribution Class held several times a year by T2G Technical Training Group.
