Good point.should probably flush out the 'white' wire thing as well. In North America the standard phase colors are Red/Black/Blue. White is reserved for the neutral and extensions of it. Just for your future reference.
well, that's even a better point, being that one can never make assumptions.Good point.
Probably should dispense with colors altogether since the usage varies from country to country. Where I live black (along with blue) is reserved for neutral, for instance.
the neutral will keep the voltages balanced.is it ok to say my voltages will not be balanced if my load is not balanced? for example if the load is customers/residents on a utility company's distribution system
Not in that example. Even though on the design side you use standard wattage calculations, the actual loads are independant and should be measured to determine actual loading.And if that is the case can i use the equations for a balanced system as an approximation to the actual load on the bank? (that is avoiding the symmetrical component calculations)
Yes to adding them, however you did indicate a transformer grouping that had different KVA ratings, and as such, the total KVA does not properly describe the configuration. If the total came to say 150KVA, but you where drawing the bulk of that on one leg, then you've greatly exceeded any one bank.And finally can i simply calculate the loads on the three single phase transformers separately and add them to get the total load the bank is doing and then just compare that total the total rated capacity of the bank to determine overloading?
