Protection Relays 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 detect internal 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
The compact relay designed for space-saving is suitable for replacement of existing ones.
Energy Saving
Low power consumption of the relay is effective in miniaturization of CT and VT as well as energy saving.
