I have an 11kv 9mw motor which has recently been visually inspected. Endwinding bracing showed signs of cracking & various pieces of packing have become loose. This machine has annual on line partial discharge testing carried out & reports submitted do not highlight problems. Before carrying out any remedial work on the stator winding I would like to confirm the stator coils are not moving in the slot & likely to cause high levels of discharge. I am told you can carry out a TVA discharge locating probe test on the machine which would highlight any discharge in the slot portion of the machine. Does anyone know where to find information on this type of test? Does anyone know if this type of test gives good results?
