Transformers play an important role in electrical power distribution and transmission systems, as they facilitate step-up and step-down voltage for distribution and transmission purposes. Because of its electricity to be transmitted efficiently. To protect transformers, various devices are fitted on…
The dielectric strength of transformer oil is known as BDV or break-down voltage. A Transformer Oil BDV test is performed to find the dielectric strength of transformer oil. BDV is the minimum voltage to withstand the capacity of transformer oil…
Step down transformer is an essential component of many electrical systems. They are used to convert high voltage, low current power into low voltage, high current power. This is important because many devices and appliances require lower voltage than what…
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…
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…
Voltage control is performed by changing the transformer turn ratio. This is achieved by providing Tapping on the transformer winding. In a tap changing transformer, taping is either provided on the primary or on the secondary winding of the transformer.…
There are in general two types of transformer Shell type and core type transformer These two types differ from each other in the manner in which winding wound on the magnetic core. Core type Transformer In core type, the magnetic…
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…
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…
