High Voltage Side Of A Transformer

A single phase voltage transformer basically consists of two electrical coils of wire one called the primary winding and another called the secondary winding.

High voltage side of a transformer.

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. Variation of alternator field current. Equivalent circuit of transformer. 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.

In some distribution transformers the tap changer resolution can be up to 1 for fine adjustments. 99 of the power transformers are designed to operate using these tap changers only. 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. In a step up transformer the voltage coming out is higher than the voltage going in so the output is the high side and.

Inserting resistance or inductance in the supply circuit from alternator. A 460 v 2400 v transformer has a series leakage reactance of 37 2 ω as referred to the high voltage side. Transformers are use to step up and step down the voltage of electricity. This variation of input voltage to the primary side can be done by.

Transformer taps are preferred on high voltage side why. Calculate the corresponding voltage and power factor as measured at the high voltage terminals. This type of taping is used in step up transformer where low voltage winding is in primary side and high voltage winding is in secondary side. Transformer taps are used to changing the transformer voltage level when it is connected to the load circuits.

Figure shows the tap changer circuit on secondary side with tap interval of 2 5. 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. When the transformer windings are drawn a particular high voltage winding corresponds to the low voltage winding drawn parallel to it.
