Abstract

PURPOSE: To prevent an error operation of phase-missing protecting function in a two-element relay, by means of improving a constitution of connection between a current transformer, provided in two phases of the three-phase high voltage circuit, and three current transformers, self-contained in the two-element realy.
CONSTITUTION: A lead wire 11, connected to one end of a current transformer 2 for high voltage, is wound on a core window 5 in a suitable number of turns with a winding unit 8 constructed, and a lead wire 12, connected to one end of a current transformer 3 for high voltage, is wound on a core window 6 in a suitable number of turns with a winding unit 9 constructed. And the lead wire 11, after constructing and drawn out from the winding unit 8, is further wound on a core window 7 in a suitable nember of turns, and the lead wire 12, after constructing and drawn out from the winding unit 9, is wound on the core wondow 7 through an ammeter 14 in a suitable number of turns, with a common winding unit 10' constrcuted. The lead wires 11, 12, drawn out from the common winding unit 10', are connected to a point A connected to earth with another ends of secondary side of the current transformers 2, 3 for high voltage made common, respectively
