MICS is an integrated compact substation incorporating all the
substation equipment which are directly connected with each other and
mounted on steel skid-bases. Compact substation can be constructed in a
shorter period and will assure lower construction cost while maintaining
the same high reliability as the conventional scheme.
Digital controlled GIS, MV-Switchgear as well as digital protection
equipment are adopted to realize this compact substation.
Because it is skid-mounted and pre-fabricated in the factory, site work is
limited to the interconnection between the skid-base units. Therefore, the
high reliability built in the factory can be maintained.
