CONTROL TRANSFORMERS
A Control transformer are to supply power to control and auxiliary equipment’s which are not intended to connect direct supply. Control transformers are used to control supply voltage for control circuits of AC starter motor i.e. starter coils, timers, indicating lamps, electronics protection relay, etc., A control transformer is used to supply control power thus allowing lower, safer and more efficient control circuit voltage to be used in high working voltages applications The excellent inrush current handling characteristics of the transformer also makes the system more efficient.
