Understanding the Different Voltage Ratings of Molded Cast Coil Dry type transformers from China
Molded cast coil Dry type transformers from China are available in a variety of voltage ratings. It is important to understand the differences between these ratings in order to ensure that the transformer is suitable for the application.
The primary voltage rating of a transformer is the voltage that is applied to the primary winding. This rating is typically expressed in volts (V) or kilovolts (kV). The secondary voltage rating is the voltage that is produced by the transformer and is typically expressed in volts (V) or kilovolts (kV).
The insulation system of a transformer is rated according to the maximum voltage that it can withstand without breakdown. This rating is typically expressed in kilovolts (kV). The insulation system rating must be higher than the primary and secondary voltage ratings in order to ensure that the transformer will not be damaged by overvoltage.
The impulse voltage rating of a transformer is the maximum voltage that the transformer can withstand without breakdown when subjected to a short duration, high-voltage surge. This rating is typically expressed in kilovolts (kV). The impulse voltage rating must be higher than the primary and secondary voltage ratings in order to ensure that the transformer will not be damaged by a surge.
The short-circuit voltage rating of a transformer is the maximum voltage that the transformer can withstand without breakdown when subjected to a short-circuit condition. This rating is typically expressed in kilovolts (kV). The short-circuit voltage rating must be higher than the primary and secondary voltage ratings in order to ensure that the transformer will not be damaged by a short-circuit.
