Abstract:
A method for detecting an open-phase condition of a transformer having a grounded-wye high voltage side connection including monitoring current flowing in a neutral connection on the high voltage side of the transformer in real time by voltage relaying and current relaying to identify an open phase condition signature in a signal capable of characterizing change of current magnitude. A current signal may be injected onto the neutral terminal and the zero-sequence mode of the transformer monitored to detect an open-phase condition indicated by an increase in network impedance and decrease or elimination of the injection current.

Claim (Index 19):
The system of  claim 18  wherein the electronic controller comprises at least one analog input that accepts output from the current measurement probe, and at least one relay or transistor output capable of initiating alarm or tripping functions.
