We're working on a hydroelectric site with a steel penstock entering the powerhouse. There's a copper grounding grid in close proximity to the penstock, bringing concerns we may need to design cathodic protection.
I've spent a bunch of time working on it and everything seems very do-able...
Hey guys,
I've been asked to obtain a ballpark price estimate in $/km and rough installation costs for...
-5kV and 15kV three phase armoured, shielded underground or overhead cable, with fibre optic down the centre
and
-25kV and 69kV three phase submarine cables.
We'd expect the lengths...
I'm a new engineer and I've just been asked if I can find out the CT ratio used when collecting power quality data with a Fluke 1750.
I can probably find the information and provide the number, but I'd rather know what it means - might save me some time in a book.
What is a CT ratio and what...
I'm studying the power quality for a client of ours. Over a 106 day period, our Fluke 1750 data recorders observed 40 voltage-triggered "impulses". An example of one of the transient event graphs is attached.
From my understanding, impulsive transients are typically caused by lightning...
Hey guys, first post. Seeing as how I'm electrical I figured it would be best to ask electricals who may have encountered this problem.
I'm working on a hydroelectric run-of-river generating facility. We've been asked to determine whether cathodic protection is required, in light of the ~1m...
