Reply to "Transformers, sine waves, need clarification"

Some generalizations with out getting too awful technical:

  1. You won't fry any AC locomotive regardless of wave pattern (pure sine wave or chopped sine wave).
  2. Any older transformer (pre/postwar) such as the 1033, LW, KW, ZW and such are pure sine wave transformers.
  3. Most modern transformers are chopped sine wave transformers. This includes the CW, GW, ZW-C, ZW-L, TPC and PowerMaster units.
  4. There is most power delivered with the chopped sine wave transformers which can be deemed beneficial for smoke unit performance.
  5. I recall some very early MTH ProtoSound locomotives have difficulties with chopped sine wave transformers.
