The exciters are all of double-pole type, giving at 420 gives at 167 Jio kilovolt-ampercs at 2,000 volts, and as a poly-phase alternator 300 kilovolt-amperes at same speed and frequency in each case is 50 cycles. The general arrangementsof this machine are similar to those of the other two just mentione
