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 2):
A method for detecting an open-phase condition of a transformer in a low load or no-load condition and having a grounded-wye high voltage side connection, comprising injecting a signal onto a neutral connection of the transformer, and, monitoring current flowing in a neutral connection on the high voltage side of the transformer to identify an open-phase condition signature in a signal capable of characterizing change of current magnitude.
