Transformer oil testing is a crucial part of transformer maintenance, as the oil serves as electrical insulation between the winding and tank and acts as a cooling agent. Over time, the oil can become contaminated, which can degrade its insulating…

The vector group of transformer shows the phase difference between the primary and secondary sides of the transformer. There are different ways in which transformer high voltage and low voltage winding is connected. Based on HV and LV winding connections,…

Consider an AC voltage of magnitude “V” having frequency “f” is applied to the primary side of the transformer. ac flux Φm is set up in the transformer core, this flux links with the both primary and secondary winding of the transformer.…

The Scott connection of the transformer is a standard method of connecting two single-phase transformers to perform the three-phase to two-phase conversion and vice versa. Scott connection of transformer is also known as T – T connection. In Scott-T connection, two…

The working principle of the transformer is based on Faraday’s law of electromagnetic induction. The three-phase power transformer is the main device of every power system. the main function of transformer is to step up or step down the voltage…

The transformer is the main device of the transmission and distribution network hence its reliability is important in every aspect. The transformer must be able to deliver the required power to load. single transformer unit is used for distribution purposes…

Transformers are said to be connected in parallel operation when their primary connected to a common supply and secondary connected to a common load. The function of the transformer is to deliver power to the locality, city. But in some cases, a…

Magnetic Oil Gauge is also referred to as MOG. it is a device that is fitted on the conservator tank to monitor the transformer oil level. The MOG is a small circular dial shape window placed on the side of…
