  If the percentage copper loss and voltage at the consumer terminals are to remain the same in the two cases, calculate the additional percentage load that can be supplied by the AC system. Assume balanced load in the two cases and unity power factor in the case of AC. A 3 phase ring main system has 4 busbars with 11 kV fed at point A.

  When either generator is lost, the operating generator will supply power for all aircraft DC loads. Two inverters operating from DC power produce the required single-phase ac power. Two 325-amp slow-blow fuses, referred to as current limiters, are used to tie the main buses and provide fault protection.

  The laterals may be three-phase, two-phase (two phases of the three-phase feeder with a neutral), or single-phase (one phase from the single phase feeder and a neutral). The laterals are usually protected with fuses so that faulted laterals do not cause interruption at the feeder level. Standard secondary voltage levels are . 120/240 single phase
