The rated value of the customized 10kv transformer is the regulation made by the manufacturer for the normal use of the transformer. The operation of the customized 10kv transformer under the specified rated value can ensure long-term reliable work and good performance. Its ratings include the following:
1. Rated capacity: It is the guaranteed value of the output capacity of the customized 10kv transformer in the rated state. The unit is expressed in volt-ampere (VA), kilovolt-ampere (kVA) or megavolt-ampere (MVA). Since the transformer has a high operating efficiency, Usually, the rated capacity design values of the primary and secondary windings are equal.
2. Rated voltage: refers to the guaranteed value of the terminal voltage of the customized 10kv transformer when it is no-load, and the unit is expressed in volts (V) and kilovolts (kV). Unless otherwise specified, the rated voltage refers to the line voltage.
3. Rated current: refers to the line current calculated from the rated capacity and rated voltage, expressed in A (A).
4. No-load current: the percentage of the excitation current to the rated current when the customized 10kv transformer is in no-load operation.
5. Short-circuit loss: the active power loss when the winding on one side is short-circuited and the winding on the other side is applied with voltage to make both windings reach the rated current. The unit is expressed in watts (W) or kilowatts (kW).
6. No-load loss: refers to the active power loss of a customized 10kv transformer when it is running without load, expressed in watts (W) or kilowatts (kW).
7. Short-circuit voltage: also known as impedance voltage, it refers to the percentage of the applied voltage and the rated voltage when the winding on one side is short-circuited and the winding on the other side reaches the rated current.
8. Connection group: Indicates the connection mode of the primary and secondary windings and the phase difference between the line voltages, expressed in clocks.
