Reasonable lighting circuits: Loss lighting circuits accounted for about 4% of the input energy, the main factors affecting the lighting circuit is power supply and loss of wire cross-sectional area. Most lighting voltage is 220V, the lighting system may be a single-phase two-wire, two-phase three-wire power supply, three-phase four-wire three ways. Three-phase four-wire power loss is much smaller than other power supply lines. Therefore, the lighting system should maximize the use of three-phase four-wire power supply.
