RE: Re[2]: Looking for advice on datacenter electrical/generator
Assuming the genset was running under load, how often would the oil filter need to be changed? Are there any other issues that would need to be addressed in a sustained power outage? As far as genset maintenance that is.

I thought it was the exact opposite. Diesel fuel has much better lubricity than LPG/CNG/gasoline.
diesels need frequent oil filter changes because they load the oil up with soot. the oil itself can last a long time. richard -- Richard Welty rwelty@averillpark.net Averill Park Networking 518-573-7592 Unix, Linux, IP Network Engineering, Security

i suggest you get that info from an engineer for the outfit that supplies your generator. my familiarity with diesel maintenence is with transportation applications, and i'm not even going to attempt to guess at how to map milage intervals to the generator application (i bet locomotive guidelines might be relevant, as modern diesel locomotives are really generator sets anyway.) if you do try and go with extended runs between oil changes, at intervals take samples and have professional analysis done. this is standard practice for large truck fleets and other transportation and industrial applications. you can run a long time on the oil, but you need the analysis to correctly recognize when the jig is up. richard -- Richard Welty rwelty@averillpark.net Averill Park Networking 518-573-7592 Unix, Linux, IP Network Engineering, Security

Agreed. They will have a spec. A genset of any size is more like a $$E3 cisco than an $500 Gateway; you should have access to real tech support and detailed advice as needed. ...

This will also vary with the engine oil capacity. In other words, if they built it with 3x the normal oil capacity, it can go longer between turndowns. But if you are really thinking continuous service, you better plan on 2 or 3 gensets and a rotation. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
