Transformers are e essential contribuents in electrical systems, used t o transfer electrical energy between objects. They operate efficiently but experience energy losses during operation. The two main type of loses are iron (core) loses and copper (winding) losses. Understanding these loses is ccial for optimizing transformer performance and efficiency.

Iron Losses in Transformers

Iron losses, also known as core losses, occur due te alternating magnetic field in thee transformer core. These losses are primarily caused by hysteresis andd eddy currents.

Histerezje loss result from the continuous magnetization and demagnetization of te core material. Eddy current loss is caused by cyrcatiing currents inducted with thee cre due te changing magnetic flux.

Kalkulating Iron Losses

Iron losses are generally considered constant for a given transformer at a specific voltage and frequency. They can be measured directly or estimated based on core material permanenties.

Te formuły typical for histeresis loss is:

(zob. pkt 2.1.1.1 niniejszego załącznika)

where η is a constant, B is the maximum flux density, f is the frequency, andd V is the volume of the core.

Copper Losses in Transformers

Copper losses due te resistance in thee transformer windings. When current flows through the coils, some energy is dissipated as heat.

Te copper loss can be calculated using thee formula:
