MV/LV substation monitoring - Sentinel FRTU
Sentinel-FRTU (Feeder Remote Terminal Unit) / Centraliser of data for the remote monitoring of MV/LV transformer substations.
Main characteristics
Installed in MV/LV transformer substations, the Sentinel-FRTU centralises data and events collected in a power substation and sends this information remotely to a control IT centre therefore:
-
Monitors the main components of a MV/LV substation
- Fault passage indicators (FPI / FCI)
- Substation environment
- MV/LV transformer
- Low voltage panel board
- Collects the main LV electrical amounts
- Monitors these amounts and generates alarms or events
- Stores and timestamps these events and measures
-
Reproduces the alarms, measurements and events locally or remotely via a communication means (GSM/GPRS, Ethernet) to:
- Field agents (receiving SMS alerts)
- Operations managers (ex. on-call staff)
- A remote computer system for analysis or monitoring
Key points:
- Powered from the substation’s 230 Vac LV
- Collects data from measurement units
- Two groups of 4 digital inputs (door opening contact, water level, etc.)
- Two PT1000 inputs for monitoring temperatures
- Four communication ports
- Onboard web server
Advantages
- Easy installation, on new structures and when retrofitting
- Better perception of balance between loads and production
- Integration of optimised renewable energy
- Monitored quality of the distributed energy
- Highlighted phase imbalances
- Easy prioritisation of necessary network improvements
Uses
- Private network and public distribution network
- Any type of MV/LV substation can be monitored
