I am trying to design a set of 3 phase heating elements for a 120/208 volt system. The purpose of these is to maintain a constant load on a generator when no load is present. The load will be 30 amps.
My question is:
- Do I find the necessary resistance of individual elements by E/I (120 volts/30 amps) or is it different since the three phases are connected together?
- Will an individual heating element consume more power on 3 phase Y than it would on single phase 120volt?
- If I choose to use elements connected in delta what what would the calculation for resistance be?
- What would be the increase in power consumtion for a given set of elements switched from wye to delta?
Thank you
