A heater capacity is 3.0 KW on 415V . if supply voltage is
380Volt . what is heater capacity on 380volt . and how
calculate and give formulas . Prakash veer singh

Answer Posted / rajendra

given Volatage = 415 volts, capacity on given voltage= 3kw
solution:-

while 415volts ac supplied than capacity of heater is 3kw
therfore 1volt supplied than capacity of heater will 3kw/415
so on380 volat supplied than capacity will be
3ooo*380/415=2.746kw
the anser will be 2.746 kw heater capacity on 380volts

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
