How many of you were around to see or lived in an area where the power utility supplied 25,40 or 50 cycle power before the conversion to 60 cycle? And when did the conversion take place?

If you need these frequencies now and the use is 3 phase, a VFD will do nicely at relatively low cost. It takes single or 3 phase, converts it to DC and then makes 3 phase at almost any frequency desired. Mine will produce from .1Hz to 400Hz (cycles) in increments of .1Hz. A 50Hz motor will run Ok on 60Hz, but will run about 20% faster.

During the early days of the Mercury Manned Spaceflight Project, they wanted some flipping digital 24 hr clocks for some control rooms. Purchasing agent with more money than brains insisted on and paid for 12 hr digital clocks that the motor was specifically and unquestionablely designed for 24 cycle 110 v power. If'n plugged into 60 cps, sure made time fly until motor burned out..... .Dell

if memory serves me the City of New Orleans still uses 10 HZ. power to pump water from the canals over the leeves into the river. They are very old units dating back to the turn of the last century or so.If they are not still in use they were taken out in the last 5-10 years.

We still generate 25 cycle for the railroad here in S.E. PA
There are also several Frequency Converters (60 hz to 25hz)on the system up and down the east coast. A few are still rotating type, the newer ones are static, SCR type.

There was some 25 cycle around Rochester NY till 53, I believe, in Churchville. A few years ago you could still see the pennstock entry in Black Creek.
Rochester NY had an area in the city core with DC until 62. The power company finally bought rectifiers for DC customers to end that service.
Company I worked for as a kid used to buy large 25 cycle motors and reconnect them to run on 6o cycle for resale.

The Rankine station (1500 feet upstream of the Horseshoe Falls) is still operating 2 of its 11 generators producing 25 cycle which is shipped to Buffalo. The future of this achitectually beautiful building (Standford White 1905) is in doubt as the water lease expires in 2009 and at approx 129 feet head is not very efficient compared to 300feet at the Sir Adam Beck stations.

I am trying to confirm that the Huntley steam station in Buffalo stopped generating 25 cycle about a year or two ago or is going to do so shortly. I am trying to find out who still uses 25 cycle in the Buffalo area. Must be old companies with ancient equipment. Anybody have any ideas??

Most 25 cycle production in the Niagara Falls ended with the collapse of Schoellkopf #3B and C in '56 and decommisioning of #3A and Adams #1 and 2 with the opening of Robert Moses in '61.

PS Any one have details on Schoellfopf #1 (1881 using Brush dynamo and 12 or 16 Brush Arc Lights). I only have a list of the initial customers. What about #2? It operated from 1896 to 1914 and one of its first customers was PRC (now Alcoa)?

Here in the United Kingdom, the system is 50Hz.

I brought over a big Canon office copier that is 60Hz only... if anyone can advise how I might convert, I'd be most grateful. The machine cost over $2,000 about 8 years ago, and I'd hate to throw it out. It will start up (I have a transformer to convert the 115volts to 220volts) but it will not operate, so is useless unless I can convert to 50Hz.
Many thanks for any assistance. Kind regards to all who read this. Fentoids... [email protected]
