Dispersing the clouds: gain clear insight into your bushings using advanced diagnostic methods

March 1, 2018

Bushing diagnosis can include various methods, from a simple visual inspection or a conventional power/dissipation factor measurement, to the latest high-tech broadband dielectric frequency response measurements.

This article explains the different bushing insulation types and shows which problems can occur in bushings and which diagnostic methods can be used to detect them. Each measurement has its advantages and disadvantages and some are more suitable for onsite measurements, others for quality control of new bushings. Case studies show the effectiveness of advanced dielectric measurement principles in detecting moisture and aging problems.
