Zillion VRS
Vertical retrofit supervision solution

The Zillion VRS – Vertical retrofit supervision solution is a comprehensive retrofit solution designed for the efficient modernisation of low-voltage panels installed in substations and pole-mounted applications. Its compact column-type cabinet design enables straightforward integration into existing installations, occupying the same footprint as a standard fuse switch.

Thanks to its Rogowski coil-based measurement system, the solution can be installed without interrupting the electrical supply, significantly reducing operational costs and intervention times. Its optimised architecture minimises wiring requirements by integrating power supply and communications into a single cable, resulting in a cleaner, safer and more organised installation.

The solution provides accurate voltage and current measurement per feeder and phase, delivering the same performance as traditional fixed monitoring systems. In addition, the Rogowski coil mounting system ensures high accuracy and reliability, even in demanding operating environments.

An ideal solution for network operators and utilities looking to digitalise and modernise existing infrastructure in a fast, safe and cost-effective way.

Value Proposition

Integrated retrofit for existing low-voltage panels. The solution integrates directly into the panel, occupying the space intended for a fuse switch. Its design reduces the required wiring and enables fast and safe installation. Depending on the configuration, it can be installed without interrupting the power supply, allowing new measurement and monitoring capabilities to be added to panels already in service.
Modular architecture adaptable to each installation. It combines sensing, measurement and communications in a single solution. Its modular architecture enables the integration of both Zillion and third-party devices, adapting to the requirements of each installation.
Integrated electrical measurement in a compact solution. It enables voltage and current measurement at feeder and phase level, with accuracy equivalent to fixed monitoring solutions. It is compatible with different sensors, including Rogowski coils, whose fixing system helps ensure measurement accuracy.
Fast installation and reduced wiring. The solution integrates directly into the panel and reduces the required wiring. Depending on the configuration, it can be installed without interrupting the power supply, adding new measurement and monitoring capabilities to panels already in service.

Primary Use Case

Integrated solution for modernising existing low-voltage panels through a compact and modular retrofit architecture. Zillion VRS integrates directly into an available fuse switch position, combining sensing, measurement and communications in a single unit. Its design enables fast installation and accurate monitoring at feeder and phase level, without structural modifications or additional enclosures and, depending on the configuration, without interrupting the power supply.
