ELECTROMOTORES perform an inspection to determine the presence of stator partial discharge activity, and the degree of its progress, both in the slot and end windings. The Generator maintenance history as well as test results like Power Factor and Partial Discharge, are taken into consideration for this objective evaluation.

ELECTROMOTORES Engineering Group then analyses the inspection data and results in order to arrive at recommendations on the work which the machine may require. This may include full or partial renovation of the Corona Protection System, and other improvements to the Insulation Systems.

A complete kit of materials for performing the required work is brought in from the USA and delivered to site (including Technical Sheets and MSDS).

ELECTROMOTORES assure the best technical procedures for this level of preventive maintenance, in order to effectively extend the life of the unit.
