Abstract
We demonstrate the use of IEC 61850 process bus transformer relays together with optical CTs for the detection of open phase conditions on the high side of a range of step-down power transformers. A set of optical CTs generates 12 waveforms which are slotted into six IEC 61850-9.2LE data streams which are in turn input into the relay programmable stream logic for the detection of open phase conditions.
