Maintenance and maintenance of relay protection devices
Facilities need to perform installation tests, implement preventive maintenance programs, and perform comprehensive commissioning tests to verify the integrity of both existing protective relay systems and new protection systems. Although failure of a protective relay system may have severe local or regional impacts, most protective relay systems are not required to operate to prove they are in working order. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. ABB has developed a preventive maintenance concept for the well-established SPACOM, RE500 and Relion series relays. These relays have been in the market for more than 20 years.

Multi-wavelength light source calibration in Jordan
In this paper, we demonstrate an approach that allows for reliably and rapidly (at timescales below 30 ms) varying the synthetic wavelength arbitrarily across multiple orders of magnitude which are prerequisites for dynamically reconfigurable multi-wavelength interferometry. Multi-wavelength optical information processing systems are commonly utilized in optical neural networks and broadband signal processing. However, their effectiveness is often compromised by frequency-selective responses caused by fabrication, transmission, and environmental factors. We provide electrical, physical, and mechanical calibration for a wide variety of systems, subsystems, test. Single-wavelength interferometry achieves high resolution for smooth surfaces but struggles with rough, industrially relevant ones due to limited unambiguous measuring range and speckle effects. For those customers who wish to do their own.
