I have some nuisance tripping of distribution line fuse links feeding a pad mount transformer. I suspect the fuse is not appropriate for the transformer. The transformer is rated at 45 kW, primary voltage is 4800, secondary is 480. The load is a 40hp motor with a soft start/stop so the inrush...
This forum has been very helpful. For reference, Im planning on stepping up 480 3 ph to 4800 for 4500 ft and then back down to 240 for submersible 35 hp pumps. Additionally I want to pull house power at the terminus. Someone mentioned TRANSIENTS.
This got me worried that the house will be...
In discussions with the county engineer, he suggested that I could design my line myself and stamp it. P.E.ME ...as long as the calcs were reasonable. I may be over my head here but his big issue seemed to be the the voltage loss in ACSR 2 over a 9000 foot run at 4160 3 phase. The load is 26...
Im having a tough time finding a source for power poles. 40ft. Internet search doesnt turn up much for a "power pole" querie. Im in So CAl. I have located some used poles but am concerned about grading them. Is there a standard for grading so I dont buy pig in a poke?

As an ME Im a little out of my field but I have a 3000 foot overhead run to make from where Edison wants to put the meter in (4 wire/277/480) to my well. I was thinking of using a std residential type xformer to step up the 277/480 to 4800 or another voltage for the run and then step it down at...
It has been suggest in this forum that I use 4800 or 4160 voltage for a 1.5 mile service extension. I'm am planning on installing a wind turbine (induction motor/generator) at the site to reduce my energy costs. California will allow zero net type of generation buy back. My question: is the...
Im planning on putting in a private electic line to my farm and retain ownership of the line. It appears that one possible way edison will connect is to meter at the beginning of my line at 480 VAC. The distance from there to my pumps is 1.2 miles so I was planning on xforming up to 4800V for...
