protection used in transformers:
buccholz device,earth fault protection,over current,over voltage,merz price,etc
breather:
wen transformer heats up oil(immersed)also heats resulting volume increase in oil.wen cool volume decreases resulting intake of air.to prevent moisture in air from entering inside silica gel is used.wen silica gel changes color simply dry it(in sun like clothes).somethin similar to human body breathing without moisture content

in laymans terms gaddi ka reserve tank.oil garam hoke volume badhta hai to extra conservative mein ghusta hai
