Additionally, the DTM now supports Ethernet connectivity with compatibility for DNP3 and MODBUS protocols, offering flexible and efficient network integration. It provides continuous, meter-grade precision performance monitoring of high-value, mission-critical, low-voltage pad mount and conventional pole mount transformers.

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.

KEY ADVANTAGES                 

Transformer State-Of-Health. The DTM provides remote access to real-time transformer health data and automated threshold alarms for condition-based maintenance planning by continuously monitoring the key indicators of a transformer's performance, including temperature and load.

Transformer Life Prediction. The DTM tracks a transformer's loss of life and employs advanced predictive algorithms to forecast the estimated remaining run time. It ensures a near-constant assessment of the transformer’s health, considering real-time conditions and applying a calculated dynamic acceleration factor to accurately predict the cumulative loss of life.

Power Factor Monitoring.  The DTM provides a transformer’s power factor, which is a trend of useful power delivery. 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.

High-Performance Hardware. A powerful industrial IOT-grade processor and sophisticated polyphase energy measurement integrated circuit provides superior onboard computation capability and Power Quality Monitor-level fidelity.

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).  

ALARMS & NOTIFICATIONS

With the CONVERGE™ web interface, utilities can be managed by exception with customised threshold alarms and notifications, such as Voltage Signal Delta, Current Signal Delta, Fault Current, Voltage Sag and Swell, K-factor harmonics, top/Bottom Tank Temperature, Temperature Delta, Winding Hot Spot Load Ratio, Winding Load, and Winding Hot Spot Temperature.

TRANSFORMER LIFE PREDICTION

By continuously monitoring the key indicators of a transformer’s performance, including temperature and load, the DTM not only tracks a transformer's loss of life 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 applied to any unmonitored time before installing the DTM. 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 safely communicate with the web-based UNITE™ asset management database. UNITE™ provides user-friendly access to all distribution transformer performance data for convenient centralised analysis and reporting.

Asset Management.  UNITE™ is a sophisticated IoT database with advanced data visualisation 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 type of 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 for the secondary transformer.

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

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

Setup & Configuration. All user interface communication, including alarm and setting configuration, 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.
