Franklin DTM-4-VZ Distribution Transformer Monitor
The Franklin Electric Critical Power INCON® DTM-4-VZ provides precision monitoring of transformer output voltage, phase loading (current), temperature, and power factor. Designed to improve power distribution and streamline equipment maintenance across an entire network of transformers, this rugged system is engineered for single-phase, split-phase, or three-phase transformers with a secondary output of 480 volts or less (phase to neutral).
Key Monitoring Capabilities & Alarms
The DTM-4-VZ offers remote access to real-time transformer health data and features automated threshold alarms for critical parameters:
- Voltage Signal Delta and Current Signal Delta
- Fault Current
- Voltage Sag and Swell
- K-Factor Harmonics
- Top and Bottom Tank Temperature (with Temperature Delta)
- Winding Hot Spot Load Ratio and Winding Load
- Winding Hot Spot Temperature
Package Contents
The system is housed in a weather-proof enclosure and includes the following hardware for immediate deployment:
- 1x Weather-Proof Transformer Monitor
- 5x Voltage Leads
- 4x Split-Core Rogowski Coils
- 2x RTD Temperature Sensors
- 1x Verizon SIM Card for wireless connectivity
System Compatibility
This monitor integrates seamlessly with the UNITE IoT asset management database (annual software subscription sold separately). The software delivers real-time diagnostics, centralized data storage for network-wide monitoring, and remote analysis via smartphones, tablets, notebooks, or workstations.
