Abstract
Transformer ground differential protection relays (device 87G) have been used to protect the windings of resistance-grounded transformers. A number of strategies have been utilized with electromechanical relays in the past. With the advent of the multifunction digital protective relay, these strategies can be adapted to continue this form of protection
