In this article wye (star) and delta connection is discussed with respect to line-line, line-neutral voltages and currents. Additionally, the…
Transformer Connections: Phase Shift and Polarity
Phase shift and phase polarity between two windings of a single-phase transformer depends on how the windings are wound on…
Duplex Reactor
Duplex Reactor or Duplex Current Limiting Reactor consists of two otherwise single-phase reactors physically arranged such that their magnetic fields…
Star and Delta Connection of Capacitors
Power capacitors in 3 phase capacitor bank connections are either delta connected or star (wye) connected. Between the two types…
Current Limiting Reactor
Current Limiting Reactor (CLR) is used to reduce the available short circuit level to a value that matches the rating…
How to calculate reactive power of a transformer?
Transformer reactive power consumption Power transformers ‘consume’ inductive VARS during operation. This is due to the reactive power requirement of…
