The MV system is, in fact, a 3-phase 4-wire system from which single-phase distribution networks (phase and neutral conductors) supply numerous single-phase transformers, the secondary windings of which are centre-tapped to produce 120/240 V single-phase 3-wire supplies. Description: The BSL is illustrated in a low-voltage distribution panel wiring diagram. It consists of three main components: the voltage measuring circuit, secondary circuit protection, and the energy metering circuit. Many countries are currently converting their LV systems to the latest IEC standard of 230/400 V nominal (IEC 60038). MV/LV. With secondary selective service, each distribution transformer must be able to supply the entire load for maximum reliability benefits.
