Transformer

Transformer is the static piece of equipment used for step up and step down the voltage for economic transmission and utilization of electrical power.

In this section we are adding all the technical articles related to transformer like step up transformer, step down transformer, ideal transformer, efficiency and losses, regulation, percentage impedance.

We will also discuss about parallel operation of transformers, copper loss and no load losses and its calculation, all types of routine and type tests, converter duty transformer,dry type transformer, k factor of transformer, maintenance of oil filled and dry type transformer, transformer protection equipment like buccoltz relay, PRD and oil and winding temperature measurement etc.

We will also discuss about the open and short circuit test on transformer.

PRD of Transformer|Pressure Relief Device for Transformer

Why Pressure Relief Device(PRD) for Oil Filled Transformer? The winding of the transformer is housed in the transformer oil tank. The oil is used in

Why does not Transformer Work with DC Supply?

This article describes why DC is not used in transformers. The transformer functions on the principle of Faraday’s Law of electromagnetic induction. When AC is

Single Phase Transformer and Application of Single Phase Transformer

The transformer transforms voltage from one level to another without changing the power and frequency. The transformer is static electrical equipment, and it does not

Ideal Transformer-Properties, Phasor Diagram, Working

What is an Ideal Transformer? An ideal transformer is free from all losses. It has zero copper and iron loss and zero leakage flux, and

Shell Type Transformer- Construction, Working & Applications

The HV and LV winding is wound around the central limb. The central limb carries the entire flux (Ф ). The flux (Ф ) divides into two equal part and thus each side limbs carries the half (Ф/2 ) of the total flux(Ф ). As a result, cross section area of the central limb is two times of the side limbs area.The arrangement of the winding around the central limb is as given below.
