Distribution Transformer Monitor

The INCON® Distribution Transformer Monitor (DTM) provides continuous, meter-grade precision performance monitoring of high-value, mission critical, low voltage pad mount transformers and conventional pole top transformers. 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.

1

Transformer Life Prediction

The DTM not only tracks the loss of life in a transformer, it utilizes highly developed algorithms to forecast the 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.

2

Customized Alarms & Notifications

With the ability to connect up to UNITE®'s user interface, utilities can manage by exception with customized threshold alarms and notifications covering voltage signal delta, current signal delta, fault current, voltage sag and swell, K-factor harmonics, and winding hot spot load ratio and winding load.

3

Data-Driven Decision Making

With the ability to monitor and trend analytics on phase by phase basis, temperature, and Power Factor for an entire network of transformers, utilities are armed with powerful information regarding power distribution and equipment maintenance.

4

High Performance Hardware

A powerful industrial IoT grade processor and sophisticated polyphase energy measurement and integrated circuit provide superior on-board computation and Power Quality Monitor level fidelity.

5

Power Factor Monitoring

Real-time monitoring of power delivery efficiency, which is a trend of useful power delivered. Power Factor helps utilities determine the most efficient distribution of power during peak times to ensure the delivery of high-quality substation power when their customers need it the most.

6

Deploy Anywhere at Scale

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 option. Standard protocols include DNP3 and MODBUS, enabling utilities to deploy the DTM anywhere and at scale.
