WebSurge comparison testing 12,13 is based on the principle that coils of same motor with no winding defects, are identical having same value of R, L and C. Surge comparison test is … Weboccurrences. Surge testing will predict motor burn-out due to turn-to-turn or phase-to-phase shorting. Surge testing should be added to a regular predictive maintenance program. It should be used in conjunction with high potential or insulation resistance testing of the primary insulation as well as mechanical evaluation such as vibration analysis.
