number of electrical phases

A transformer that, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.

vacuum circuit-breaker

tag class

A circuit-breaker in which the contacts open and close within a highly evacuated envelope.

wet transformer

equipment class

A power transformer of which the magnetic circuit and windings are immersed in oil.
