Construction of Phase Shifting Transformer
#PHASE SHIFT SERIES#
The first one is the shunt unit that is connected in parallel through the transmission line whereas the second one is the series unit that is connected within series through the transmission line. The construction of a phase-shifting transformer mainly includes two sets of the transformer. The flow of load flow in the line will be modified & also other transmission lines’ load flow can also be changed because they are arranged in parallel.

So the phase angle can be shifted within the ends of the transmitter and receiver of a line. The theory of phase-shifting transformer is, the flow of power throughout a transmission line can be proportional toward the sine of the disparity within the phase angle of the voltage among the end of transmitter & the receiver of the transmission line.

As compared to a traditional transformer, PSTs are extremely complex power transformers including more tap changers, windings as well as a number of connections among the 3-phases. These transformers are extremely specialized devices that need leading-edge construction & manufacturing skills united through stringent quality control. By avoiding overloads of the system as well as instabilities, these transformers defend and HV equipment as well as transmission lines from thermal overload, so that it improves the capacity of the transmission system & controls the flow of power among various networks for parallel cables or overhead lines. These transformers mainly allow for controlling the flow of power within the transmission grid separately for the generation. When the transmitted energy increases then it will push the network to the edge, enhancing the threat of network insecurity. Phase Shifting TransformerĪ phase-shifting transformer or PST is an essential component that is used to enhance the efficiency of the AC network. These two transformer’s configuration mainly induces the phase shift. This can be fed through a shunt transformer.

The working principle of a phase-shifting transformer mainly depends on an injection of a phase-shifted voltage source into the line using a series-connected transformer. This can be done by changing the difference of voltage phase angle among the system nodes. A special kind of transformers like PST or Phase Shifting Transformer is used to control the active power flow on 3-phase transmission networks.
