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…
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…
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…
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.…
The current transformer (CT) is a type of instrument transformer designed to measure high-value current in the power system. The primary has few numbers of the turn of heavy wire, and the secondary of the current transformer has many turns of…
Difference between Current Transformer (CT) and Potential Transformer (PT) Current Transformers (CT) and Potential Transformers (PT) are used to measure the current and voltage in a circuit of the order of hundreds of amperes and volts respectively. A CT has…
