Impact power quality problems transformers

The book delves into the various stresses that transformers endure during their operational life, including electrical, mechanical, thermal, chemical, and electromagnetic pressures. It highlights the gradual deterioration of insulation from installation, leading to a decline in mechanical and dielectric strength, as well as thermal integrity. The text emphasizes that transformer failure occurs when these operational stresses surpass the component's capacity to withstand them, providing a comprehensive understanding of transformer reliability and maintenance challenges.
