Transformer Monitoring System
The iDEV Transformer Monitoring System (TMS) is an intelligent asset monitoring solution designed to provide continuous visibility into transformer health and operating conditions. By combining non-invasive sensors, edge computing, secure communications, and cloud analytics, the platform enables utilities to detect developing faults early, reduce unexpected failures, and optimize maintenance activities through real-time insights.
Keeping Critical Assets Healthy
Distribution transformers are among the most valuable assets in a power distribution network. Conventional maintenance practices often rely on periodic inspections, making it difficult to detect developing faults before they result in failures.
Unexpected transformer outages lead to service interruptions, increased maintenance costs, reduced equipment life, and customer dissatisfaction.
How TMS Solves This
The iDEV Transformer Monitoring System enables utilities to continuously monitor transformer operating conditions, allowing maintenance teams to identify abnormalities early and take corrective action before failures occur.
Real-Time Transformer Monitoring
Continuously monitors critical transformer operating parameters to provide complete asset visibility and early fault detection.
Non-Invasive Deployment
Designed for rapid installation using non-invasive sensing technologies, minimizing downtime and eliminating the need for major transformer modifications.
Intelligent Alerts & Notifications
Generates configurable alerts whenever operating parameters exceed predefined thresholds, enabling faster response to abnormal conditions.
Cloud-Based Asset Monitoring
Securely transmits field data to the cloud, providing centralized dashboards, reports, and historical trends for utility operators.
Predictive Analytics
Uses historical operating trends and intelligent analytics to identify developing faults and support predictive maintenance strategies.
Secure Communication
Supports reliable LTE/4G communication with encrypted data transmission and secure device authentication.
