Introduction

Transformers are fundamental components of modern electrical systems, enabling the efficient transmission and distribution of electricity. Understanding how transformers function and their role in global power equipment solutions is imperative for engineers and energy professionals.

What is a Transformer?

A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It is commonly used to increase ('step up') or decrease ('step down') voltages in power applications.

How Do Transformers Work?

Transformers work on the principle of mutual induction. The core component of a transformer includes primary and secondary windings. When an alternating current flows through the primary winding, it creates a time-varying magnetic field around the core, inducing a voltage across the secondary winding. This voltage induction largely depends on the turns ratio of the windings.

Transformer Parameters and Numerical Analysis

Key parameters that define transformer operation include the turns ratio, core losses (hysteresis and eddy currents), copper losses, as well as efficiency and regulation. For instance, the efficiency of a transformer can be calculated as:

• Efficiency (%) = (Output Power / Input Power) × 100.

Numerical analysis often involves calculating the windings' impedance to ensure optimal design and operation. A typical step-down transformer may have a primary voltage of 11,000V and a secondary voltage of 230V. The power rating can vary significantly, with utility transformers generally rated from 500 kVA to over 1,000 MVA.
