Eliminate Electrical Failure

Electrical Failure

Abstract: An Electrical Arc Furnace near a hyperactive railway traction line was facing electrical failure from an unusual power quality harmonic distortion problem. The Gigantic 22kA copper bus bar used to overheat visibly red-hot, vibrate audibly loud loosening nuts and bolts and wear out affected plates.

Comprehensive Power Quality Analysis

Power Quality Analysis

Abstract: Large continuous process plants are increasingly resorting to use of non linear loads (NLL) such as DC drives, variable speed AC drives, UPS, increased electronic controls etc. to improve performance and productivity of their plants. The plant engineers are increasingly facing unfamiliar problems related to power quality (PQ) mainly problem of distortion of fundamental wave shape and associated effects.
