Emergency maintenance undertaken on a generator for the sugar and ethanol sector

WEG provided emergency support to a company in the sugar and ethanol sector, performing specialised maintenance services on the stator of a 43,750kVA, 13.8kV, 4-pole GE generator, a critical piece of equipment for the plant’s power generation system.

The project began with the execution of the RM Guardian service on-site in January 2026, when high partial discharge levels were detected, followed by the shipment of the equipment to WEG’s service facility. The scope included cleaning and oven-drying cycles, RM Guardian testing, double Vacuum Pressure Impregnation (VPI), application of anti-corona and anti-tracking coatings, recovery of corona-affected areas to reduce partial discharge levels, as well as electrical testing, assembly, and cable reconnection.

The machine was returned to the customer within 17 days, in an operation carried out within a compressed schedule to ensure the equipment was available before the start of the sugarcane harvest season.

This project represents an improvement in the operational reliability of the plant’s power generation system, contributing to the stability of both the production process and the facility’s cogeneration operations.

The customer maintains an ongoing relationship with WEG for maintenance services, operating four industrial facilities and approximately 13 generators and motors supported by WEG’s service portfolio. Through this project, WEG further strengthens its presence in the sugar and ethanol industry, delivering solutions that enhance the reliability, availability, and performance of assets that are critical to industrial operations.
