    Refurbishment of HV Electrical Machines  -  Debunked

    We all know that some of our new motors and generators seem to develop major problems after only about 5 -10 yrs requiring Major Remedial Repairs and even Winding Replacement.

    It seems that market and end user cost pressures have led to significant reductions in machine margins (or no margins at all), adding considerable increases in Mechanical, Electrical and Thermal duties and stresses.

    Generational designer change have in turn, led to blind trust in computer design without “Feel and Intuition” so that some Hard Learned Lessons of the Past had been forgotten and Old Problems get reinvented.

    What you'll experience first hand

    During this site visit, Tony O'Brien and his team from Australian Winders will take us through how failing HV machines' operating life can be extended by replacing and refurbishing equipment also get a better understanding of the various processes and tests involved in the refurbishment process and will include:
