Open circuits are more common in low voltage cables than at medium or high voltage. Open circuits are usually the result of failed connectors, or broken and/or corroded conductors. The reason that open circuit failures are rare in higher voltage systems is that arcing will occur in the conduction path, leading to overheating, failure of the insulation and a short circuit.

Strain GaugeStrain Gage measures the strain (amount of contraction as well as expansion caused by external forces) on any object. The strain gaugewas invented in 1938 by Edward E. Simmons and Arthur C. Ruge. Any basic strain gauge consists of an insulating flexible backing that supports a metallic foil pattern. The gauge is attached to the object under stress using an adhesive.
