Distribution Transformer Monitor
Distribution Transformer Monitor
The INCON™ Distribution Transformer Monitor (DTM) provides continuous, meter-grade precision performance monitoring of high-value, mission critical, high voltage pad mount transformers and conventional pole top transformers.
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 the powerful information necessary to make informed, data-driven decisions regarding power distribution and equipment maintenance.
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 to the transformer secondary.
Four split-core Rogowski Coils measure load current. Five voltage leads measure Phase A, Phase B, Phase C, as well as neutral and ground. Two magnetically mounted RTD sensors measure top and bottom transformer temperature.
Four powerful 25 lbs. magnets integrated into the mounting plate allow the DTM to be installed vertically or horizontally without any drilling or adhesives.
The DTM is powered by the transformer itself, using the Phase A and Neutral voltage leads. No external power source is required.
An MQTT / TLS Comms Protocol allows the DTM to securely communicate with the web-based UNITE™ user interface.
SETUP & CONFIGURATION
All User Interface communication including configuration of alarms and settings, and alarm resetting can be done locally via Wi-Fi using a web browser or remotely via the cellular connection.
UNITE™ provides user-friendly access to voltage, temperature, current and Power Factor data for convenient analysis and reporting.
With the UNITE™ map view, users get a consolidated view of an entire network of transformer health and performance.
