Discover how Smart Nosy by SEA MARCONI is revolutionizing the approach to resin transformer maintenance, offering continuous monitoring and cutting-edge diagnostic services to optimize performance and prevent failures.
Resin transformers are essential components in many electrical distribution systems, valued for their safety and reliability. However, compared to oil-filled transformers, they generally have a higher failure rate and lack tools for diagnosing their health status. SEA MARCONI has developed an innovative solution, Smart Nosy, which is radically changing the maintenance approach for these critical assets.
The Importance of Maintenance in Resin Transformers
Contrary to popular belief, resin transformers are not entirely “maintenance-free”. Regular and well-planned maintenance is essential to:
- prevent unexpected failures;
- extend the service life of the transformer;
- ensure the safety of the installation.
The absence of an insulating fluid such as oil does not eliminate the need for periodic checks. In fact, it requires a specific and targeted approach.
Best Practices in Resin Transformer Maintenance
Regular Visual Inspections
Visual inspections are the first step in a good maintenance strategy. During these inspections, it is important to check:
- the integrity of the resin;
- the cleanliness of the windings;
- the cleanliness of the transformer enclosure;
- any cracks or signs of overheating;
- the presence of vibrations or abnormal noises;
- the proper tightening of bolts.
Temperature Monitoring
Temperature control is crucial for resin transformers. Excessive temperatures can degrade the insulation and significantly reduce the transformer’s service life. It is advisable to:
- install temperature sensors in strategic points according to industry regulations;
- regularly monitor the readings;
- set alarms for above/below threshold temperatures.
Cleaning and Ventilation
Unlike oil-filled transformers, resin transformers heavily depend on the ventilation of the enclosure. Therefore:
- ensure the proper functioning of forced ventilation systems, if present;
- ensure that the surrounding environment is free of dust, debris, leaks, and mold.
Innovative Solutions: The Era of Smart Monitoring
The advent of IoT technologies and advanced monitoring systems is revolutionizing the approach to resin transformer maintenance. In particular, the system Smart Nosy, developed and patented by SEA MARCONI, represents a significant leap forward. Smart Nosy is equipped with a sort of electronic nose that detects any abnormal behavior of the transformer.
Smart Nosy offers:
– Automatic, continuous, and non-invasive monitoring
– Periodic monitoring with targeted laboratory analysis
– Timely notifications in case of threshold exceedances
– A web platform for recording maintenance interventions (logbook)
– Early detection of anomalies (functional pathologies)
– Risk reduction
This innovative approach allows you to monitor the transformer’s vital parameters and detect potential issues early on, increasing reliability and reducing operational costs.
Implementing an Effective Maintenance Strategy
To implement an effective maintenance strategy for resin transformers, it is recommended to:
- Develop a detailed maintenance plan
- Properly train technical personnel
- Use advanced monitoring tools like Smart Nosy
- Record all maintenance activities (Smart Nosy web platform)
- Regularly update the maintenance plan based on collected data
Conclusion
Maintenance aimed at extending the service life of resin transformers is now possible. Innovative products like Smart Nosy by Sea Marconi allow 24/7 monitoring of resin transformers, sending notifications in case of anomalies.
Smart Nosy monitors in real-time the transformer’s vital parameters and, through its patented innovation, “sniffs” the odor emitted by the resin to detect any abnormal behavior before it leads to a sudden failure.
