The Esplanade substation contains one 250-kw and four500-kw converting units. Each unit consists of a 5500-volt,three-phase synchronous motor with a 250-volt genera-tor connected to each end of the shaft. These generatorsare used as shunt machines in series across the two outercircuits of the 460-volt three-wire lighting system while forthe railway supply they are provided with series windingsfor compounding. This substation also contains a 50-kwstarting set and three 50-kw negative boosters for the
