it monitors the transformer’s vital parameters online from any location in real-time. It will diagnose & amp; send alerts/notifications which you will receive on a Laptop or Phone whenever there is any abnormality sensed in the transformer. This allows maintenance to be scheduled and corrective action to be taken before the failure actually happens. The risk of failure is reduced using alarm rules and detection of deviation from a reference value or threshold (e.g., oil and winding temperature).
