A one-family dwelling has six 3-kW electric wall heaters (with individual thermostats) and five room air conditioners. Two air conditioners are rated 10.5 amperes at 230 volts, and the others are rated 7.2 amperes at 115 volts. A service calculation is being performed, using the optional method . How many volt-amperes should be included (after demand factors) for the heating and air conditioning? (Assume heater kW ratings equivalent to kVA)

In the distribution transformer;In the transformer used for the distribution of electricity to the houses, 3.3 kilovolts enters and 400 volts come out. When we make the phase-neutral calculation, that is, when we divide it by √3, we get 230 volts and 220 volts coming to the sockets. Where does the remaining 10 volts go? (Can you explain with figure) is this about 30 degree phase shift?
