Continuous SF₆ Monitoring for Critical Energy Infrastructure.
Neohance delivered and installed an SF₆ gas detection solution for a new 150kV substation.
Designed for continuous monitoring and early leak detection, the system supports personnel safety, equipment protection, environmental responsibility, and the reliable operation of critical power infrastructure.
Project Overview
Location: The Netherlands
Project period: 2026
Project: New 150kV substation
Solution: SF₆ gas detection and continuous monitoring
Focus: Safety, environmental compliance, and infrastructure reliability
The Challenge
Modern substations require dependable monitoring systems to support safe and reliable operations.
SF₆ is commonly used in high-voltage electrical equipment because of its strong insulating properties. However, leaks must be detected quickly to protect personnel, maintain equipment performance, reduce environmental impact, and avoid operational disruption.
The new 150kV substation therefore required a reliable detection solution capable of continuously monitoring critical areas and providing early warning of potential SF₆ leaks.
Our Scope
Neohance was responsible for delivering and installing the SF₆ gas detection solution, including:
- SF₆ gas detection equipment
- Continuous monitoring of critical areas
- Detector positioning and installation
- Alarm and monitoring infrastructure
- System configuration
- Functional testing
- Technical documentation
- Final commissioning and validation
Continuous Monitoring and Early Detection
The installed system continuously monitors the substation environment for the presence of SF₆ gas.
Early leak detection allows operators to respond quickly before gas concentrations increase or affect personnel, equipment, and operational continuity.
The solution supports:
- Personnel safety
- Equipment protection
- Operational continuity
- Environmental compliance
- Infrastructure reliability
Supporting Reliable Energy Infrastructure
As energy networks expand and modernize, reliable monitoring systems play an increasingly important role in maintaining long-term grid stability.
The SF₆ detection system supports the safe and efficient operation of the substation while helping the operator manage environmental and operational risks.
By combining continuous monitoring with early warning capabilities, the solution contributes to a more resilient and dependable power network.
Supporting Environmental Responsibility
SF₆ is a potent greenhouse gas, making the prevention and early identification of leaks particularly important.
Reliable gas detection helps operators identify potential releases, take corrective action, and support responsible management of high-voltage infrastructure.
This project demonstrates how operational safety, equipment reliability, and environmental responsibility can be addressed through a single monitoring solution.
