It seems that the end of the world crowd has policy makers greatly worried about coronal mass ejection events, solar flares, etc reaching out and sending civilzation back to the stone age. The fear is that induced low frequency AC or induced DC currents will destroy power transformers...
Apparently some policy folks with a vested interest "just" discovered a paper written by some graduate students from the People's Republic of China (aka the PRC).
Those pesky graduate students must have PhD's in marketing...and I hope they are getting paid for talking to the news agencies...
Ok, we are doing some "SmartGrid" work...reconductoring, switch installations, communications and control. We have federal funds to spend...
I have been asked to give my thoughts on using a wireless 802.11 network to communicate the control signals to the associated switches, etc. Not...
We are looking at using our tertiary windings to serve our 13.8 kV dsitribution system. Presently our tertiary's hardly do anything--they serve the station load and provide protection with their polarizing currents, etc.
Typically we use two 250 MVA 230/115 kV auto-transformers with the...
So, we had a lively discussion at work today regarding when we should use a fault current interrupting device (i.e. a circuit breaker) to serve a load versus something like a circuit switcher or load break switch.
Somehow we have been using the mythical figure of 100 MW of "tapped load" on a...
