State regulators ordered Southern California Edison to identify fire risks on its unused transmission lines like the ...
A transmission line is a far more complex piece of equipment than many people realize. In its simplest form it may be considered as just a pair of wires merely carrying ac power. Usually in these ...
Southern California Edison began charging customers for hundreds of millions of dollars of maintenance on its aging ...
One of the issues that beginning electronic engineers must grasp is the concept of impedance and impedance matching, epically with respect to transmission lines, cables, and connectors. This FAQ ...
In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF ...
The National Electric Safety Code (NESC) includes a clause sometimes referred to as the “5-mA Rule,” which states: For voltages exceeding 98 kV ac to ground, either the clearances shall be increased ...
This story was produced by Grist and co-published with Verite News. When a winter storm knocked out Texas’ power grid in 2021, the scale of the devastation it wrought was exacerbated by a singular ...
