NEC design compliance, system protection and Arc Flash Hazard

IEEE Transactions on Industry Applications, 2012
The National Electric Code specifies limits on settings of transformer overcurrent protective devices that directly affect system protection. However, compliance with NEC design guidelines does not assure adequate system protection. The result can be zones of poor or non-existent protection and “Extreme Danger” Arc Flash Hazard Ratings (AFH).

Scan design at NEC

IEEE Design and Test of Computers, 1989
The authors describe scan path, NEC's implementation of the scan design approach to design for testability. Designers at NEC have found that scan path greatly contributes to the reduced testing and maintenance cost of their products. The authors discuss several implementations of scan design and compare four implementations, including two scan-path ...

Automated design of a three-dimensional fishbone antenna using parallel genetic algorithm and NEC

IEEE Antennas and Wireless Propagation Letters, 2005
A new antenna configuration, named the three-dimensional fishbone antenna (3DFA), as an improvement of the conventional fishbone antenna, is presented in this letter. It consists of dipoles that may be of nonuniform lengths with unequal spacing and are allowed to tilt in haphazard directions. To achieve a high endfire gain and good impedance match, the
