Raising the Bar for Switchgear Safety

Berlin

Tested Beyond the Standards

Our SF₆-free gas-insulated switchgear (GIS) uses dry air insulation and has been tested to perform under the toughest conditions. These tests validate both mechanical robustness and electrical safety:

  • Seismic testing: Proven mechanical stability under strong vibration and shock, ensuring reliable operation in earthquake-prone regions.
  • Internal Arc Classification (IAC) AFLR at 31.5 kA: Certified operator and equipment protection in case of internal faults, with energy safely contained and     redirected.
  • 💨 Pressure withstand testing: Each unit is tested at 1.3 × maximum operating pressure, as per IEC routine test requirements for dry-air GIS, ensuring long-term tank integrity and leak-free operation.

Built-in Safety for Every Operator

Beyond mechanical and electrical resilience, our switchgear integrates features that reduce human error and make operation safer and easier:

  • Standard and custom interlocks prevent unsafe switching sequences.
  • Fully motorized disconnector (DS) and vacuum circuit breaker (VCB) enable complete remote operation, limiting the need for personnel to come close to the switchgear, as operation can be done remotely.
  • Viewports with optional cameras provide visual confirmation of switch positions, adding another layer of operational assurance.

Smart Safety Through IoT Monitoring

Nuventura’s GIS can be equipped with IoT sensors for temperature, humidity, and tank pressure, providing continuous, real-time monitoring. These insights enable predictive maintenance, helping operators detect potential issues early and improve grid reliability.

A Safer and Cleaner Future

At Nuventura, we see the transition to SF₆-free switchgear as an opportunity to redefine safety standards. Every test, interlock, and sensor is part of our mission to deliver a cleaner, safer, and smarter grid — without compromise.

Explanation of the relay protection functions required in MV grids

Every part of an electrical grid must be protected from faults such as short circuits, overloads, or insulation breakdowns. Protection relays act as the grid’s nervous system — constantly monitoring electrical signals and commanding circuit breakers to isolate faults before they cause widespread outages or damage. This article gives an overview of the key protection functions.

AIS vs GIS — Combining the Best of Both Worlds with SF₆-Free Technology

For decades, utilities and industries have relied on two main types of medium-voltage (MV) switchgear: Air-Insulated Switchgear (AIS)and Gas-Insulated Switchgear (GIS). Each technology offers unique advantages — and trade-offs. At Nuventura, we believe the future doesn’t belong exclusively to one or the other. It lies in combining the strengths of both, enabled by our SF₆-free dry-air insulation technology.

Why Voltage Levels Matter in Medium-Voltage Grids

In medium-voltage (MV) power distribution, voltage level defines everything — from how efficiently electricity travels through the grid, to how equipment is designed, rated, and operated.

Protection Relays – The Intelligence Behind Medium-Voltage Switchgear

In every medium-voltage (MV) primary substation, protection and control systems play a crucial role in ensuring grid safety and reliability. While circuit breakers and disconnectors handle the flow of electrical power, it’s the protection relays that act as the system’s intelligence — constantly monitoring, analysing, and responding to the grid’s behaviour.

Raising the Bar for Switchgear Safety

In the medium-voltage (MV) grid, safety is non-negotiable. Every component inside a substation must protect not only the power supply, but also the people operating it. At Nuventura, we believe that moving towards SF₆-free switchgear should not just support the environment — it should also set a higher benchmark for safety.
