Introduction voltage transformer

Voltage transformer is a mcb circuit breaker with a core. It mainly consists of a secondary coil, the core and insulation components. When applying a voltage on a winding U1 when the iron core generates a air circuit breaker flux φ, under the law of electromagnetic induction in the secondary winding to produce a secondary voltage U2. Change the primary or secondary winding turns, can produce different primary voltage and the secondary voltage ratio, which can be composed of Electric energy meter voltage transformers. Voltage transformer to convert high voltage to low voltage in proportion, ie 100V, voltage transformer primary side connected to the primary system, the secondary side connected measuring instruments, relay, etc.; mainly electromagnetic type (capacitor voltage transformer applications wide), and another non-magnetic, such as electronics, photoelectric.
