Harmonics-transformer derating

Proceedings of Industrial and Commercial Power Systems Conference, 2002
Power transformers supplying nonsinusoidal load current often need to be derated. The ANSI/IEEE C57.110-1986 standard provides a method by which derating may be performed. However, derating only provides an estimate of remaining transformer capacity, since subsequent load may significantly change the relative harmonic current values.

Cable crossings-derating considerations. I. Derivation of derating equations

IEEE Transactions on Power Delivery, 1999
Dangerously high interference temperatures can occur at points where cables cross external heat sources even when the crossing occurs at 90/spl deg/. For perpendicular and oblique crossings, these interference temperatures are usually ignored for distribution circuits, whereas for transmission cables, corrective actions in physical installation ...

Intelligent derating for reliability

Proceedings IEEE International Symposium on Intelligent Control 1988, 2003
An approach to design for reliability based on the formulation of derating criteria, the determination of levels of criticality for derating analysis, and production rule derating is presented. The approach utilizes Prolog procedures to generate a user-definable hierarchy of parts classifications whose working parameters follow user-definable ...

Cable crossings-derating considerations. II. Example of derivation of derating curves

IEEE Transactions on Power Delivery, 1999
For pt.I see ibid., vol.14, no.3, p.705-14 (1999). Cables crossing other heat sources either perpendicularly or at oblique angles will experience a rise in conductor temperature which should result in ampacity derating. In the first part of the paper a mathematical model for calculation of derating factors was presented.
