The larger the transformer capacity, the smaller the primary and secondary DC resistance values, which are inversely proportional.
Thermal energy is stored solely through a change of temperature of the storage medium. The capacity of a storage system is defi ned by the specifi c heat capacity and the mass of the medium used. Latent heat storage is accomplished by using phase change materials (PCMs) as storage media.
The rated transformer capacity is the apparent power value input to the transformer, including the active power and reactive power absorbed by the transformer itself. Methods for judging transformer capacity include: 2) Measurement with a capacity tester is carried out through a low short-circuit current test using a transformer capacity tester.
Assuming that the transformer under test is 1000 kVA, I1N and I2N can reach 57.7 and 1448 A, respectively. It can be seen that under the rated conditions, the current and power supply capacity of the short-circuit test are large.
