It is digital protection relays for high/extra-high-voltage power distribution.
MELPRO-S series provides optimum protection compactly.
The continuaously monitoring electronic circuits from input to output can detectinternal failure before that failure causes damage on the power system, thereby improving reliability.
Sixteen sorts of operation time characteristics are installed as a time-delayed element. The optimal operation time characteristic can be chosen with the coordinated characteristic of the overcurrent relay at the sending distribution substation.
Various relay elements are contained compactly. It is the best for replacement of existing.
It is a low power consumption article. The miniaturization of CT and VT is realizable.
