Three-phase transformer

The capacity is three identical single-phase transformer combination. It has three core columns, each column is the core around two coils of the same phase, is a high Circuit breaker, the other is the low voltage coil. air circuit breaker electricity is generated equal amplitude and frequency are equal, phase difference of 120 ° electric potential generator is called three-phase generator;mcb circuit breaker generator as a power source, called the three-phase power; three-phase power supply circuit, called three-phase circuits. U, V, W is called three phase, phase to phase voltage between the line voltage, the voltage is 380V. Called phase voltage between phase centerline, the voltage is 220V.
