Abstract :
A LARGE FREQUENCY CHANGER was installed in 1934 at the Safe Harbor Power Station to supply 25-cycle power to the Pennsylvania Railroad. It consists of a 24-pole 3-phase 60-cycle synchronous motor rated at 29,000 kva at 90 per cent power factor solidly coupled to a 10-pole single-phase 25-cycle generator rated 31,250 kva at 80 per cent power factor.
