Microprocessor-based protective relays
IEEE Industry Applications Magazine, 2009This article describes the benefits of microprocessor (muP) relay performance and its capabilities beyond previous protective relaying technologies. This article also discusses a multiple quality-measurement approach to observing, measuring, and then calculating muP relay reliability and unavailability.

Lightning protection for microprocessor based electronic systems
Industrial Applications Society, 36th Annual Petroleum and Chemical Industry Conference, 1989The authors address the issues of lightning threats, suppressor components, and guidelines for selection and placement of protectors for microprocessor-based electronic systems. It is noted that more than 75% of all field failures of microprocessor-based electronic systems are caused by electrical overstress. The fundamental ingredients of an effective

A Microprocessor Protection Architecture against Hardware Trojans in Memories
2020 15th Design & Technology of Integrated Systems in Nanoscale Era (DTIS), 2020Software exploitable Hardware Trojan Horses (HWTs) have been currently inserted in commercial CPUs and, very recently, in memories. Such attacks may allow malicious users to run their own software or to gain unauthorized privileges over the system. Therefore, HWTs are nowadays considered a serious threat both from academy and industry.

Microprocessor Implementation of Breaker-Fail Protection
IFAC Proceedings Volumes, 1980Abstract This paper describes the implementation of a digital technique for breaker-fail protection, using rate of rise of current at zero crossings as an indicator of current magnitude. Results obtained on a PDP 11/10 computer for single and multiple circuit breaker failure (with and without C.T. saturation) are given.

Reliability of a Microprocessor-Based Protection Switching System
Bell System Technical Journal, 1978High-capacity transmission systems usually include one or more hot spares for protection. When a regular transmission channel fails, its signal is rapidly transferred to the spare channel under the control of protection switching circuits so that there is little signal degradation or interruption.

A 16b microprocessor with on chip memory protection
1983 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1983A 16b microprocessor, containing on-chip memory management and protection, which executes up to 1.5-million instructions per second,will be discussed. The chip (334×340 mils2) with 120K transistors uses an 8MHz clock and provides a 242.5ns data access time at the pins of the chip.
