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.

Product Information

DATA-DRIVEN DECISION MAKING

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.

TRANSFORMER LIFE PREDICTION

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.

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 the 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.

UNITE™ ASSET MANAGEMENT DATABASE

A secure MQTT communication protocol allows the DTM to communicate with the web-based UNITE™ asset management database safely. UNITE™ provides user-friendly access to all distribution transformer performance data for convenient centralized analysis and reporting.

ASSET MANAGEMENT
UNITE™ is a sophisticated IoT database with advanced data visualization tools for Franklin Electric monitoring systems like the DTM.

ANALYSIS
UNITE™ provides user-friendly access to voltage, temperature, current Power Factor data, and more for convenient analysis and reporting. 

CONSOLIDATION
Arm service and maintenance personnel with a consolidated view of an entire network of distribution transformer health and performance data.

EASY INSTALLATION

The DTM can be applied to any distribution transformer with a secondary output of 480 volts or less, phase to neutral. This includes single-phase, split-phase, or three-phase transformers. Installation has been kept simple, with only a few connections required to the transformer secondary.

SIMPLE CONNECTIONS

Four split-core Rogowski Coils measure load current. Five voltage leads measure Phase A, Phase B, Phase C, and neutral and ground. Two magnetically mounted RTD sensors measure the top and bottom transformer temperatures.

MAGNETIC MOUNTING

Four powerful 25 lbs. magnets integrated into the mounting plate allow the DTM to be installed vertically or horizontally without any drilling or adhesives. 

SETUP & CONFIGURATION

All user interface communication, including configuration of alarms and settings, data viewing, and alarm resetting, is made via the CONVERGE™ web interface. Configuration can be done locally via Wi-Fi using a web browser or remotely through the cellular connection.

 

     

     

    TRANSFORMER STATE-OF-HEALTH

    By continuously monitoring the key indicators of a transformer’s performance, including temperature and load, the DTM provides remote access to real-time transformer health data and automated threshold alarms for condition-based maintenance planning.

    TRANSFORMER LIFE PREDICTION

    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. 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.

    POWER FACTOR MONITORING

    The DTM provides a transformer’s Power Factor, which is a trend of useful power delivered. Power Factor helps utilities to determine the most efficient distribution of power during peak times and to ensure the delivery of high-quality outbound power when their customers need it the most.

    DEPLOY ANYWHERE AT SCALE

    A built-in Cat M1/NB2 cellular modem allows the DTM to communicate via a cellular network, enabling utilities to deploy DTMs virtually anywhere and at scale (i.e. one unit to thousands of units).
