Power transformers are one of the static devices, i.e. there are no moving parts, so the amount of losses is minimal and their parts
It consists of Bushing made of conductor wire, which is wrapped with insulating cellulose sheets that are saturated with oil. As a result, condensate or self-expanding capacitors are created between these cellulosic sheets and the wire is directed towards the outer surface of the (Bashing).
 Radiator Cooling Sheets Most transformers with large couriers are equipped with cooling sheets, which are metal sheets with a large surface area or they may be in the form of tubes and their usefulness is to receive the hot oil and cool it and then return it
  Voltage Transformers are used to power small devices and energy meters, that is, they feed simple loads
 How are current transformers connected to protective devices? current transformer
 Circuit Breaker, which is useful for controlling electrical energy in the case of generation, transmission and distribution
