Transformer Station Monitoring
High- and medium-voltage grids are already widely digitalized and monitored.
However, low-voltage grids are still largely operated without real-time insights.
One key reason is the lack of networking and digitalization in transformer stations.
The Transformer Station Monitor (TSM) from Acal BFi was developed in collaboration with Stadtwerke München as a retrofit solution for exactly this purpose.
We monitor the entire local grid station (ONS) and the low-voltage grid in compliance with §14a regulations.
The TSM captures and monitors a wide range of key parameters, including:
- Current and voltage
- Temperatures
- Short circuits and ground faults
- Motion detection, and more
All measurements are continuously checked for threshold violations, triggering alerts when necessary.
Data transmission is tailored to your specific requirements, supporting Ethernet, LoRaWAN, and mobile networks as standard communication options.
Digitalizing Local Grid Transformer Stations
To digitalize existing local grid transformer stations, they must be retrofitted with the appropriate equipment.
This allows potential grid disturbances to be detected before shutdowns occur, enabling early intervention to prevent major damage.
With the Transformer Station Monitor (TSM), we offer an out-of-the-box solution for transformer monitoring and grid surveillance.
Our TSM is specifically designed for retrofit applications.
Housed in a high-quality plastic enclosure with an IP67 rating, the unit is optimally protected against environmental influences.
Key functions of the Transformer Station Monitor:
- Assessment of the local grid transformer station to evaluate grid conditions
- Early fault detection to prevent failures
- Analysis of outage causes
- Monitoring of key parameters such as temperature, humidity, door access, and alarms
- Remote resetting of short-circuit shutdowns
By using wired or wireless networking, the TSM enables decentralized event reporting from the stations.
These insights are made available to grid operators, for example, in control centers, eliminating costly and time-consuming on-site service visits.
In summary, the TSM significantly enhances supply security and improves grid stability.
