hi, so i know at the distribution level transformers are used to step down the voltage to be supplied to the residential/commerial customers. I was just wondering though. what actually feeds the transformers and where are these feeds coming from?also, could anyone briefly explain what is inside an actual transformer such as (primary elbows, secondary, bus bars, etc)thanks in advance!!
Hi pal! A transformer is a device which converts electrical energy. just remember that. now we know energy is E VI.t right? Now a transformer has two ends. one is the primary winding and the other is the secondary winding. winding means wound wires ;ole am inductance wire. the two of them are connected by a metallic core through which magnetic flux flows linking the two windings. Since energy is constant Voltage of primary x Current in primary Voltage in secondary x Current is secondary Now, since the number of turns of the 2 winding are different, thus the flux linkages are different i.e. N x phi so induced emf by faraday's law is different. so if secondary number of turns is suppose 10 and primary is 1000 then if voltage in primary is 1000V secondary is 10V this is how it steps down. so the transformer is FED by a high or low voltage source via busbars. this is as briefly as i can explain without boring ya!! :)
