Integrated hotspot temperature real-time monitoring system for power transformer

Overview

A leading Transmission & Distribution (T&D) company in India had installed hotspot temperature monitoring systems from multiple OEMs across their power transformers. However, these systems operated independently, making it difficult for technicians to access real-time data from the field in a single, centralized platform. Manual recording of hotspot temperatures from remote field systems often caused delays and inaccuracies, particularly during peak summers and heavy monsoons. These gaps in temperature logs increased the risk of transformer failure, operational disruption, and financial losses. To address these challenges, the T&D company turned to digital maintenance solutions and adopted Rugged Monitoring’s enterprise-level APM platform, RM EYE.

The Challenge

The lack of real-time monitoring and historical trend analysis has left the T&D company unable to detect emerging thermal issues before they escalate.

Manual Data Collection

Hotspot temperatures were tracked manually, leading to missed or inaccurate readings.
Lack of Real-Time Data

Absence of a real-time monitoring platform limits visibility and hinders timely decision-making.
Frequent Equipment Failures

Recurrent Overheating caused unexpected downtime, leading to costly outages and reducing transformer life.
Safety Risks

Excessive heat increases the risk of fires or explosions, endangering personnel and affecting regulatory compliance.
Inefficient Maintenance

Reactive or time-based maintenance resulted in higher costs and lower operational efficiency.

The Rugged Monitoring Solution

Rugged Monitoring implemented its enterprise-level APM, RM EYE, a multi-site, multi-asset platform, delivering centralized, real-time monitoring through a non-intrusive, scalable architecture.

Unified Hotspot Temperature Monitoring

A centralized visibility for operators from both regional & national command centres to monitor all 4 power transformers in real-time.
