DYKA designs, manufactures and sells plastic piping systems for the sanitation, drilling and irrigation sectors. Each year during the summer shutdown, we proceed to the control of a 500kW asynchronous motor with shock waves to determine if the engine needs to be overhauled.

This year, the inspection revealed an insulation fault on the engine (insulation value divided by two in one year) which is typical of a pollution of the winding by fouling.

Our teams are immediately mobilized to remove, clean the rotor and the stator and put the asynchronous motor back on their Saint Austreberthe (62, France) factory in just a few days during the summer stop.
