Transformer Life Prediction

Mar 13, 2024

The INCON® Distribution Transformer Monitor (DTM) provides continuous, meter-grade precision performance monitoring of high-value, mission critical, low voltage pad mount and conventional pole mount transformers. By continuously monitoring the key indicators of a transformer’s performance, including temperature and load, the DTM not only tracks the loss of life in a transformer but also employs advanced predictive algorithms to forecast the estimated remaining run time.

HOW DOES IT WORK?

CONTINUOUS MONITORING

The DTM continuously assesses transformer loading and thermal conditions to calculate the accumulated loss of life in real-time, updating at approximately two second intervals.

ACCELERATION FACTOR

After each interval, the DTM updates the accumulated loss of life. This considers exact interval duration and adjusts with an acceleration factor based on the loading and thermal conditions.

LIFETIME ESTIMATE

The average acceleration factor is then applied to any unmonitored time before the DTM was installed. This provides a thorough estimate of the total loss of life and can be used in predictive maintenance planning.

DATA COMMUNICATION

Choose from a built-in Cat M1/NB2 cellular modem that allows the DTM to communicate via Verizon® and compatible private LTE networks, or an Ethernet connection capable of DNP3 and MODBUS protocols to communicate life prediction data.

The DTM ensures a near-constant assessment of the transformer’s health, considering real-time conditions and applying a calculated dynamic acceleration factor to predict the cumulative loss of life accurately.

The INCON™ DTM is a cutting-edge monitoring system that leverages advanced technologies, including wireless sensors and cloud-based analytics, to provide real-time monitoring and analysis of transformer performance. It allows utilities to detect potential issues before they escalate into major problems, improving the reliability of their electrical grids and reducing maintenance costs.

With the ability to monitor and trend transformer output voltage, loading (current) by phase, temperature, and Power Factor for an entire network of transformers, utilities are armed with powerful information regarding power distribution and equipment maintenance.
