Can we connect them in starconfiguration also ? If we can then what would be the effect on heating & on load & hence on power consumption ?
what's the output power of these 12 heaters in delta configuration ? as heaters are the pure resistive loads
Yes you can , then Power (delta) = 3 x Power (star) , Look post #7.....
Delta : Resistor voltage = 380V ; R = 70.6 Ohms then P one resistor is 2045 W >> Ptot = 12x2045W = 24.54kW
Star : Resistor voltage = 220V ; R = 70.6 Ohms then P one resistor is 686 W >> Ptot = 12x686W = 8.23kW
when temperature exceeds the set value (SV) the heating stops & blower (3 phase motor) starts to run ?
viewing the terminal box of the motor
