Secondary circuit which includes part-time: 2013-06-25 Read: 1668 times First, according to the nature of the power points; an AC voltage circuit; (YH) and three-phase five-column secondary side voltage transformer voltage transformer by opening Triangle supply all circuits. All Loop 3 2, the DC circuit, the DC system, AC current loop; all circuits by current transformer (LH) on the secondary side of the power supply. A device (also known as the master device) is mainly composed of the power system, which is the direct production, transmission and distribution of electric energy equipment, including generators, power transformers, circuit breakers, disconnectors, power bus, power cables and transmission lines. Secondary device is a device to control, regulation, protection and monitoring equipment, which includes control equipment, relay protection and automatic devices, measuring instruments, signal appliances. You may also be so understood: (. UVW.L1L2L3.ABC) as long as the line that joins three current equipment. Are considered the primary circuit. Other (low current) connected devices are considered secondary circuit. Once from the main transmission. Transforming effect. While the second is a protective, monitoring, control, regulation, and so the role.
