| Popis: | The article presents the dependences of the active and reactive components of the losses of the idle transformer on the mains voltage. It is proposed to evaluate the no-load losses using an alternative method for identifying the parameters of the transformer based on high-precision synchronous measurements. Within the framework of a pilot project on a real feeder, using the technology of synchronous measurements, the dependences of no-load losses on voltage were identified. For transformers installed in a distribution network, the dependence of losses on voltage is not quadratic, but has a higher order. It was determined that the dependence of losses in a transformer on voltage for active power has a power of 6.35, and for reactive power has a power of 7.4. |
