why do power line transformers blow?

Power line transformers can blow due to several reasons, including overloading, which occurs when the transformer is subjected to a load exceeding its capacity. Short circuits caused by faults in the electrical system or external factors like fallen trees can also lead to transformer failure. Additionally, insulation breakdown due to age or environmental factors, such as moisture or extreme temperatures, can compromise the transformer’s integrity, resulting in a blowout. Regular maintenance can help mitigate these risks.
