Thermal, Electrical, Ambient (or environmental) and Mechanical (TEAM) stresses act on various components of a Rotating Machine, either singly or in combinations (thermo-mechanical, electro-thermal, electro-mechanical, etc), with varying intensities, depending on design, manufacturing, operating, maintenance and storage conditions, ultimately weakening (ageing, defect formation) the structure of the Rotating Machine component (winding, insulation, bearing, shaft, etc) and ultimately resulting in failure. Based on various international surveys and studies it has been concluded that winding insulation is found to be the one of the maximum potential areas of failures in Rotating Machines.
PROGNOSYS provides Diagnostic Testing services for Generators,Transformers,Motors,Switch gears,etc., includes following techniques listed below, which will assess the condition of Machine Insulation System in total.
