Zillion LVS
Low voltage transformer supervisor

The Low Voltage Supervisor (LVS) is a three-phase monitoring device designed for distribution transformer monitoring in both indoor secondary substations and outdoor installations. It enables real-time supervision of the transformer’s critical electrical and thermal parameters, providing an accurate view of its operating condition.

In addition, the LVS measures voltage, current and power, incorporates power quality monitoring, and supports temperature measurement via PT100 sensors. Information is displayed locally through its LCD screen and can be easily integrated into supervisory systems thanks to its standard communication options. As a result, the LVS becomes a key tool for anticipating incidents, improving asset availability and optimising maintenance strategies in power distribution networks.

Finally, the LVS is compatible with any type of distribution transformer and can be installed in both indoor secondary substations and outdoor installations.

Low Voltage Transformer Supervisor Value Proposition

Visibility at the Transformer Level. Electrical measurement and power quality monitoring directly at the transformer. Includes power quality and harmonic distortion information to support the diagnosis of network and transformer conditions. This provides a real view of the asset’s condition and operational performance.

Integrated Thermal Monitoring. PT100 input for continuous transformer temperature monitoring. This makes it possible to detect overheating and degradation before they lead to failures.

Easy Integration into Existing Systems. Serial and Ethernet communications with standard protocols. In addition, the LVS can be easily integrated into existing supervisory architectures.

Remote Transformer Monitoring. Enables remote supervision of transformer condition and electrical parameters, facilitating the management of distributed assets and reducing the need for field intervention.

Primary Use Case of the Low Voltage Transformer Supervisor

The Low Voltage Supervisor (LVS) is used for the monitoring of distribution transformers in secondary substations and outdoor installations. It acts as a source of electrical, thermal and power quality data, supporting asset management as well as preventive and predictive maintenance. This improves supply reliability and the operational efficiency of the secondary substation. In addition, the LVS can be used as a monitoring point at intermediate locations within the low-voltage network, extending visibility into network behaviour beyond the secondary substation.
