Neutral Point of Heater Bank

FornhamSpark
Hi,

I have an application to control a bank of resistive heating elements (52Kw) in a Star configuration from a Eurotherm Power Management unit to control heat output.

Is it standard practice to connect the Neutral Point to Neutral ?

    Well why don't you try the demonstration I did using banks of lamps connected in star on a three phase supply. Use 5+ in each bank and then simulate the fault by removing one lamp at a time from the same bank - note the change in brightness.  However, have a care, you may cause real failures in the remaining lamps in that bank. ?


    Regards
