GENERATOR REPAIR & REWIND SERVICES

When it comes to long-term reliable service, industrial generators have no rival. The near constant ability to stay active despite power failures and major systematic errors is impressive.

Manufacturing plants inherently rely on the wide functionality of these generators to keep their business lively and productive. We not only repair and refurbish your Generator but to provide root cause failure analysis on why it has failed, and provide ongoing maintenance services.

Generators are equipped with an exciter rotor and stator on alternating current generators in order to produce excitation. Exciters are inspected and tested to ensure they meet the manufacturer’s identified requirements. Our exciter rewind process includes removing all the coils from the core, cleaning and inspecting the core. The new winding will be re-manufactured using an inverter rated magnet wire and the insulation exclusively classified as follows: NEMA Class “H” An insulation system (180°C temperature limit including a 40°C ambient or 140°C rise) that by experience or accepted test can be shown to have suitable thermal endurance when operating at the limiting Class H temperature specified in the temperature rise standard for the machine under consideration. The entire Insulation System, materials, and methods of application should be equal to or better than that used by the original machine manufacturer. All components of the insulation system will be compatible with each other with respect to electrical, mechanical, and thermal characteristics. Generators are rebuilt using the highest-quality wire, insulation, and varnish materials for long-lasting repairs in the most severe industrial environments.

Exciter rotors and stators are impregnated in varnish and oven baked to ruggedize the windings.

Motor & Generator Winding Analysis is an ideal method for detecting winding issues and to monitor the dielectric strength of your winding insulation. This method is a necessary aspect of any electric generator preventative maintenance. This program can be used to troubleshoot or eliminate the motor windings as the source of a failure. It can also be used as a trending tool so we can monitor the dielectric strength of your winding insulation over a period of time. With motor winding analysis, our skilled technicians can discover early-stage problems inside electrical equipment before they become more substantial. This early detection method allows us to perform the appropriate repairs during planned downtime; in addition to reducing repair costs during unscheduled shutdowns, motor winding analysis can lessen costs associated with catastrophic component failure. Motor winding analysis is a form of non-destructive testing (NDT) that can be used for motor, transformer, and generator windings.
