FUNCTIONALITY
Our Transformer AMC services function as a proactive shield for your electrical infrastructure. We implement a structured maintenance regime that includes periodic site visits, diagnostic testing, and health assessments. Through Dissolved Gas Analysis (DGA) and electrical testing, we identify potential faults like insulation degradation or overheating before they escalate into major failures. Our team ensures that the transformer’s cooling systems, bushings, and protective relays are in prime condition, guaranteeing uninterrupted power supply and extending the equipment's operational life.

Frequently Asked Questions
Our AMC includes scheduled site visits, visual inspections, oil testing (BDV, DGA), electrical testing (IR, Winding Resistance), tightening of connections, and cleaning of radiators/bushings. It also covers detailed health reports and priority breakdown support.
For critical transformers, oil testing should ideally be done annually. For smaller distribution transformers, it may be done every 2-3 years. However, under our AMC, we customize the frequency based on the transformer's age, load, and criticality.
Yes, AMC clients receive priority emergency response. Our team is available 24/7 to attend to sudden breakdowns or tripping issues, ensuring minimal downtime for your operations.
Absolutely. We offer specialized inspection and rejuvenation services for older transformers. If the equipment is in salvageable condition, we can extend its life through oil reconditioning, replacement of gaskets, and necessary repairs.
This depends on the contract type. Comprehensive AMC packages often include consumables (like silica gel, gaskets) and labor, while non-comprehensive packages cover only labor and inspection, with spares charged at actuals. We offer both options.
