The figure shows an unreduced approximate L-type equivalent circuit to the High voltage (Primary) side of a 30 kVA, 4000V/120V, 60Hz transformer (Here, the parallel arms are shifted to the right, not to the left). In a transformer with parameters RH=1.6 Ohm, RL=1.44 milli Ohm, LH=21 milli Ohm, LL=19 micro Henry, RcH=160 kilo Ohm and LmH=450 Henry; Calculate the phasor V1 on the high voltage side, since it is known that a load with pf=0.6 (lagging) characteristics is connected at VL=120V on the low voltage side, and it is known that P2=20kW power is consumed.
Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
