In response, engineers and researchers are exploring innovations to make transformers more efficient and adaptable. These include developing solid-state transformers that can handle AC-DC conversions, flexible LPTs that can adjust impedance without changing voltage ratios, and mobile transformers for rapid deployment. Efforts are also being made to improve the longevity of traditional transformers through new insulation techniques and materials like natural esters and ceramic paper. Despite these advancements, the transformer industry faces a capacity crunch, with a need for significant investment to meet future electricity demands as global electrification efforts intensify.
Key takeaways:
