Re: California public safety power shutdowns

Radu, The fire risk is from electrical transmission lines, not from end users of electrical power. The underlying problem is that the State’s rules for line separation were ill-considered, making it possible for high-enough winds to cause “line slapping” and the resultant arcing that ignite

Re: California public safety power shutdowns

Electrical arcing happens around the country. The difference is that California, through years of unwise restrictions on vegetation control, has millions of acres of dry fuel near these powerlines. In the early 1990s, a series of restrictions were placed on logging in the West to protect the

Very strange ATT would put end users on an RFC 1918 block unless they were doing NAT to the end user. If they were doing NAT, I would expect CGNAT in the 100.something or other range. On Thu, Oct 10, 2019, 11:07 AM Mehmet Akcin wrote: > Yes > > On Wed, Oct 9, 2019 at 20:46 Javier J wrote: >

Re: California public safety power shutdowns

Sean, A diesel generator sparking a fire is extremely unlikely. A diesel generator by code must have a clear, nonflammable, area around it, and a spark arrestor on the exhaust to protect against burning particles in the exhaust. Diesel generators are not even a listed cause according to the

Telemetry System Ideas

I have an alternative view. the more generators are running, the more trucks semt to refuel the tanks, the more moving parts, the more likely an accident is prone to happen somewhere. It's thr same reason you turn your vehicles engine off when you fill up at the gas station. Diesel doesn't
