To make sure the quality and safety operation of the transformer, Users need to check and test them before operation and after operating for a long time. Tests help users easily detect some signs of damage.
SFRA is a very reliable and sensitive method or tool to measure the condition of the windings, core, and clamping structures within power transformers.
The connection of the primary and secondary winding of a three-phase transformer can be designed in different ways according to the desired application and available terminals.
The equivalent circuit diagram of a transformer is a simplified circuit in which the impedance, resistance, and leakage reactance of the transformer can be more easily calculated.
The polarity can be defined as the induced voltage direction in the primary windings and the secondary winding. If two transformers can be connected in parallel, then the polarity must be identified for a good connection of the transformer.
