Protection Relay (MELPRO-S series)
Product Features
It is digital protection relays for high/extra-high-voltage power distribution.
MELPRO-S series provides optimum protection compactlｙ.
Self-diagnosis
The continuaously monitoring electronic circuits from input to output can detectinternal failure before that failure causes damage on the power system, thereby improving reliability.
Abundant Characteristics
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.
Compactly
Various relay elements are contained compactly. It is the best for replacement of existing.
Energy Saving
It is a low power consumption article. The miniaturization of CT and VT is realizable.
