Zillion LRS
Feeder retrofit supervisor

The LRS is a live-line supervisor designed for advanced electrical monitoring of low-voltage networks, enabling installation without service interruption or power outages. Developed for retrofit applications, it provides a fast, safe and effective way to digitalise existing installations while remaining compatible with virtually any panel configuration.

Installed on the outgoing feeders of low-voltage panels, the LRS is compatible with three-pole fuse switches and circuit breakers, regardless of manufacturer or applicable standard. This makes it a universal solution for upgrading assets already deployed in the field. As a result, the LRS has become a dedicated low-voltage live-line monitoring solution for retrofit projects and the progressive digitalisation of distribution networks.

Equipped as standard with the Advanced Monitoring Card (TSA), the LRS delivers the same measurement and monitoring capabilities as other Zillion solutions, ensuring consistent data accuracy and a unified approach to network analysis. The information collected is seamlessly integrated into the Zillion ecosystem, supporting network operation, diagnostics and the ongoing evolution of the grid.

Value proposition of Zillion LRS - Feeder retrofit supervisor

Live installation without power outages.
Enables installation and commissioning without disconnecting the electrical supply, reducing operational impact and simplifying deployment across active low-voltage networks.
Comprehensive feeder and phase monitoring.
Thanks to the integration of the Advanced Monitoring Card (TSA), the LRS provides accurate voltage and current measurement at both feeder and phase level, delivering the same monitoring performance and data consistency as the rest of the Zillion ecosystem.
Universal and compatible retrofit solution.
Designed to adapt to virtually any low-voltage panel configuration, including fuse switches and circuit breakers, without requiring prior modifications or detailed site assessments.
Order, safety and speed in the field.
Its compact design and feeder-based wiring layout eliminate loose cables on the floor of the secondary station, improving safety and reducing installation times.

Primary Use Case

Real-time monitoring and diagnostics for existing low-voltage networks where continuity of supply is critical. The LRS is particularly suited to retrofit projects, asset digitalisation programmes and the progressive automation of low-voltage networks. It enables existing panels to be upgraded with advanced monitoring capabilities without service interruption and with minimal field intervention. In this context, the LRS acts as a dedicated live-line monitoring solution, supporting the phased digitalisation and modernisation of low-voltage distribution networks.

What Does the LRS Monitor?

Electrical parameters at feeder and phase level across low-voltage networks.

Load evolution and operating conditions of the network.

Key electrical indicators for network operation and diagnostics.

Abnormal conditions that may lead to network incidents, failures or operational losses.

Voltage measurement connection options.

LRS – Voltage Measurement Using Insulation Piercing Connectors

This version measures voltage through insulation piercing connectors, which create a small controlled penetration through the cable insulation to make contact with the conductor without compromising the integrity of the installation.

It provides a universal solution compatible with any fuse switch or circuit breaker configuration, making it particularly suitable for retrofit projects where fast installation and maximum versatility are required.
LRS – Voltage Measurement Using Ring Terminal Connections

Designed for panel feeders equipped with bolted terminals, this option provides a standardised and secure voltage connection through ring terminals.

Its compact design makes it particularly suitable for small enclosures and outdoor installations, while delivering the same monitoring and measurement capabilities as all other LRS configurations.
LRS – Voltage Measurement Using V-Type Terminal Connectors

This variant is designed for panel feeders equipped with V-type terminals, providing a flexible and quick-connect solution for installations where space is limited.

Like all other LRS configurations, it supports live installation, feeder- and phase-level measurement, and full compatibility with existing low-voltage infrastructure.
