Listeroid Engines / Re: PCV

I bet George at utterpower might not like that contraption.   I like his philosphy of KISS.  (Keep it simple stupid)  That things looks waaaay too complicated to be bolted to a Listeroid.   The "sock" sounds pretty appropriate however.

You're gonna have to fill me in on what the "screw PC" is all about unless you're talking Canadian politics - then I'm with you  ;)

Lister Based Generators / Re: Lister & Genhead are on the way

There certianly seems to be a lot of locomotive traffic here for a closed plant!  :P   LAV's are made next door to the locomotive plant.  The LAV division (part of GM Defense) was sold to General Dynamics.  As far as I know, locomotive production still goes on here as long as GM has orders for them and remains solvent.  I haven't been in the plant in years - but it sure is a neat place, but construction doesn't happen very fast.  It's neat when they haul a locomotive down to the airport to load it on a plane for europe.  A locomotive strapped down in the cargo hold of an aircraft - now that is cool!

I'm in London, Ontario, Canada.  Two hours from Detroit, two hours from Toronto, 6 from Ottawa.  Not really on any coast, right in the snow belt though.  (Of course you can see that from Mapquest if you still aren't sure where I am)

Lister Based Generators / Lister & Genhead are on the way

Hi all,
     Only my second post here, but here it goes:

I'm an owner of a company that sells Chinese engines/generators here in Canada.  We import them,  get them CSA approved, and sell them.  We sell gas engines from 1-13HP, and diesels from 3-10HP, generators to 5kW.  Anyways, in the process of negotiations for purchasing some 24-50kW 1800RPM enclosed liquid cooled gens, a supplier offered to send me a 15kW (Brushless, AVR and/or Manual voltage reg, 120/240, Volt/Amp/Hz gauge) gen head.  Of course, I accepted.

But, needing something to drive it with, and also needing an excuse to buy a Listeriod, I dug out an old email from Anand Enterprise, and ordered up a 25/2.

I cant wait to have all this stuff here, should be quite the little project.  I'm thinking about chain drive, but we'll have to see when it all gets here.  Of course, by the time I'm done it will have cost me more than the fully assembled 24kW silent unit with auto start etc etc, but just ordering something isn't much fun. 

I haven't seen anyone running such a large setup on this site, is there any reason why?  Maybe I might have the largest setup??  (And surely the only one with the CSA approval on it - *scoulds Canadians who have "forgotten" about it on thier generators*)  I'm also curious as to why every one has these ST heads, granted all of the standard arguments about brush/brushless on Utterpower, but the brushless units I've had and sold are VERY reliable. 

Thoughts/comments/ideas welcome and appreciated.

Thanks,


Steve

Hello,
       I've been an observer on this forum for a little while now, thought I could interject with some electrical knowlegde.  I work for a power utility that provides electricity for over 30% of the Canadian population.  I can guarantee that you aren't experiencing a frequency drop-out.  All protections in stations are set to open breakers at 57-59Hz or 61-63Hz on the high-end.  On a utility scale, this frequency swing is considered massive, and causes equally massive voltage swings.  These type of protections are what kicked in and causes the large blackout in the North East US/Canada in Aug'03. 

But it definatley sounds like you have some voltage/power factor issues.  Frequency is the only thing that is constant between the supply (generators) and the load, and utility generators shut down outside of frequency limits.  On the issue of documenting voltage though, it's certainly not hard.  Our utility allows for voltage as low as 113, and as high as 127 (measured at the customers main breaker)  anything staying outside these limits for more than 30 seconds could be grounds for a compliant or corrective action.  A simple multimeter will give you some basic readings, let me know what they are and we can talk about different fixes.

Steve

Just a reply for those who think that "mains" power is accurately transmitted.  My son lives in an upscale neighbourhood, with lots of homes  bringing prices with 6 or more zeros in them. He has been complaining his natural gas heater fan seems to dip in rpms occasionally.  I was sitting in his living room yesterday when the neighbour started using his power saw.  Every time the saw came on, the heater fan dipped significantly in speed.  I figure the neighbourhood is over populated with high draw devices and underpopulated with transformer capacity???  Don't know how to document this but would like to.  Maybe something to watch the cycles???
