A novel approach to comprehensive tests on phase-shifting transformers


Phase-shifting transformer are used to control the flow of active power in a complex transmission network, including the improvement of transmission capacity, reliability and operational safety of this network. It is an efficient and economical tool that allows you to increase the reliability and efficiency of power flow control in an overloaded transmission line in which it was installed. Therefore, information about its technical condition is also important in order to ensure a reliable operation.

The article focuses on a novel approach to perform diagnostic tests on phase-shifting transformers and presents several measurement cases which emphasize the importance of the characteristic operating states of the phase-shifting transformer. The results have shown that using a three-phase transformer test system is a very fast and efficient way to verify the operation parameters of phase-shifting transformers during commissioning and maintenance in the field.
