Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as…
Choice of Transformer Connection Diagram: The different choice of Transformer Connection Diagram are namely, Star/star: This is economical for small HV transformers as it minimizes the turns/phase and winding insulation.…
Difference Between Star and Delta Connections: Difference Between Star and Delta Connections - In star connection with earthed neutral, the maximum voltage of the phase winding to ground is 1/√3…
Three Phase Transformer Connections: In generation, transformation, transmission and utilization of electric energy it can be shown that it is economical to use the three-phase system rather than the single-phase.…
Variable Frequency Transformer | Application: So far we have considered transformers which operate at fixed frequency (50 Hz). Their purpose is to transform electric power from one voltage level to…
Autotransformer | Definition | Use of Auto transformer: So far two-winding transformers have been discussed wherein the windings are electrically isolated. When the primary and secondary windings are electrically connected…
Switching Transients in Transformer | Transformer Inrush Current: Switching Transients in Transformer - In the earlier discussion earlier steady-state operation was assumed so that v1 and Φ are both sinusoidal,…
Transformer Efficiency Formula: Power and distribution transformers are designed to operate under conditions of constant rms voltage and frequency and so the efficiency and voltage regulation are of prime importance.…
