15 OFF DUAL 1.25 MVA TRANSFORMER INDOOR SUB-STATION ARRANGEMENTS MAXIMUM INDIVIDUAL TRANSFORMER LOAD IS 50% OF THE TRANSFORMERS MAXIMUM IN AIR RATING. (IN EXTREMIS FORCED AIR VENTIALTION PERMITS AN ADDITIONAL CONTINUOUS 15% POWER TO BE TAKEN) CAST RESIN VACUUM IMPREGNATED TRANSFORMER CONSTRUCTION,HAS PROVEN HIGHER RELIABILITY AND THERE ARE NO OIL AND ASSOCIATED HAZARDS IN THE BUILDINGS TRANSFORMER L.V. SECONDARY WINDINGS ARE CONNECTED IN A “STAR FORMATION” TO GIVE CENTRE POINT EARTHING AND NEUTRAL CONNECTIONS. EACH DUAL SUB-STATION ARRANGEMENT HAS ITS OWN INDIVIDUAL EARTH MAT ARRANGEMENT. THIS ARRANGEMENT PROVIDES EXCELLENT EQUI-POTENTIAL BONDING FOR THE RELIABLE AND SWIFT OPERATION OF PROTECTION AND SAFETY DEVICES BUT PERFORMS POORLY WITH MANY E.M.C. AND ELECTRICAL NOISE TRANSMISSION ISSUES.
