A personal computer approach to overcurrent protective device coordination

IEEE Transactions on Power Delivery, 1988
The personal computer offers several advantages over both manual methods and shared-computer methods for overcurrent protective device coordination. The fast graphics display of a personal computer makes it possible to achieve a practical replacement for the light table. A computerized approach to overcurrent protective device coordination is presented.

Personal attenuation ratings versus derated noise reduction ratings for hearing protection devices

The Journal of the Acoustical Society of America, 2022
National and international regulatory and consensus standards setting bodies have previously proposed derating hearing protector ratings to provide a better match between ratings determined in a laboratory and the real-world measurements of attenuation for workers. The National Institute for Occupational Safety and Health has proposed a derating scheme
