Análise dos Testes em Transformadores: Valores para Rc e XM

Three 25kVA 2A000277V distribution transformers are connected in ΔY The opencircuit test was performed on the lowvoltage side of this transformer bank and the following data were recorded VlineOC 480 V IlineOC 410 A P340C 945 W The shortcircuit test was performed on the highvoltage side of this transformer bank and the following data were recorded VlineSC 1600 V IlineSC 200 A P340SC 1150 W What are the estimated values for Rc and XM Note that since the low side voltage is Yconnected and the high side voltage is A connected the phase values must be converted accordingly to calculate the desired parameters
