Winoa Transformer Failure

Winoa’s arc furnace transformer failed without warning, triggering an emergency call to Spark Power at 3 am.

Within 30 minutes, Spark’s team had mobilized, isolated power, and coordinated with Spark Power Hamilton’s high-voltage crew and partner Aevitas to test, repair, and re-energize the transformer.

• Developed partnerships with Aevitas and coordinated with Spark Hamilton’s high-voltage branch to complete the full scope.
• Coordinated all trades effectively to ensure a seamless workflow and safe execution.
• Utilized transformer expertise to facilitate quick and safe power restoration.
• Provided ongoing support with weekly oil samples to ensure optimal long-term transformer performance.

• Power restored within hours. 30-minute crew mobilization minimized production downtime from an unplanned transformer failure.
• Safe high-voltage emergency repair at 3 am. Spark team isolated, tested, and re-energized the transformer safely under time-critical conditions.
• Seamless cross-team coordination. Spark Power Hamilton and Aevitas partnership delivered comprehensive high and low voltage coverage.
• Ongoing transformer performance monitoring. Weekly oil samples provide continued visibility into transformer health following repair.

Our Arc furnace has been operating smoothly for almost 24 hours since the Spark team completed the repairs. The collaboration between your team and the Aevitas crews, along with your electrical testing expertise, was instrumental in addressing our concerns at every stage. Your readiness to assist on short notice ensured the project was finished promptly. We greatly appreciate your outstanding service and dedication.
