The main advantages

Monitoring can help reduce the risk of unanticipated accidents and some catastrophic failure. This can also help reduce costly cleanup, replacement, and unplanned outage costs. The key to extending the service life of important transformers is to detect early failure of the transformer as early as possible, and it will also provide significant economic and operational benefits:

It can increase the time interval between routine maintenance, reducing maintenance and maintenance costs

Reduce non-scheduled delivery time through continuous state monitoring and early fault diagnosis

Using the online model to provide transformer status information in real time, the main replacement cost can be delayed by optimizing transformer performance and extending transformer life span
