transformers are crucial for adjusting high voltages to usable levels in
various applications. Oil-cooled transformers use mineral oil for cooling and
insulation, while dry-type transformers use air or synthetic materials, ideal
for indoor settings. Specialized transformers for solar and wind energy manage
variable outputs from renewable sources. Operating within 11 kV to 33 kV and
handling currents up to several thousand amperes, they function at 50 Hz or 60
Hz. Widely used in manufacturing, utilities, and infrastructure, these
transformers require regular maintenance, including inspections of insulation,
cooling systems, and electrical connections, to ensure performance and extend
their lifespan.
