High Voltage Side Of A Transformer

A 460 v 2400 v transformer has a series leakage reactance of 37 2 ω as referred to the high voltage side.

High voltage side of a transformer.

At the same time these tap changers are always preferred to operate in high voltage side. A single phase voltage transformer basically consists of two electrical coils of wire one called the primary winding and another called the secondary winding. Inserting resistance or inductance in the supply circuit from alternator. Equivalent impedance of transformer is essential to be calculated because the electrical power transformer is an electrical power system equipment for estimating different parameters of the electrical power system which may be required to calculate the total internal impedance of an electrical power transformer viewing from primary side or secondary side as.

Variation of alternator field current. In a step up transformer the voltage coming out is higher than the voltage going in so the output is the high side and. In some distribution transformers the tap changer resolution can be up to 1 for fine adjustments. Transformers are use to step up and step down the voltage of electricity.

Equivalent circuit of transformer. The output voltage of a high voltage transformer is regulated by changing the input voltage to the primary side. In other words a high voltage winding and a low voltage winding that are drawn parallel to each other constitute a single phase transformer or two windings on the same leg of the magnetic core of a three phase. This variation of input voltage to the primary side can be done by.

For this tutorial we will define the primary side of the transformer as the side that usually takes power and the secondary as the side that usually delivers power. Transformer taps are preferred on high voltage side why. 99 of the power transformers are designed to operate using these tap changers only. A load connected to the low voltage side is observed to be absorbing 25 kw unity power factor and the voltage is measured to be 450 v.

Transformer taps are used to changing the transformer voltage level when it is connected to the load circuits. Calculate the corresponding voltage and power factor as measured at the high voltage terminals. Two types of tap changer are used which are on load.
