Research of dependences of idle losses of transformers TM-400/10 on voltage according to synchronous measurements

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