A difficult to predict electrical failure is the continuity failure. Pressure junctions are common problem sources for continuity failures. Available tools to search for pressure junction problems include low resistance testing, temperature monitoring using physical contact between sensor and heated part, pyrometer temperature monitoring, infrared photography and visual inspection. While each method...
The IEEE standard 1584-2002 is the recognized standard regarding the calculation of incident energy output from an alternating-current three-phase arcing fault. While that standard does not provide incident energy calculations for the much more common single-phase-to-ground fault, it explains that the expectation is that such a ground fault will either self-extinguish or else will escalate into a...
Ground water flow systems in the rugged central Wasatch Range, Utah were, investigated by solute and isotopic methods. Six types of ground water systems were identified on the basis of rock type and structure. The systems are broadly grouped into four categories: (1) granitic systems; (2) non-granitic systems: (a) unconsolidated alluvial systems, (b) consolidated sedimentary rock systems, and (c)...
