EA Technology Barrier Spacer UHF Sensor
The EA Technology Barrier Spacer UHF Sensor is a cutting-edge solution designed to enhance partial discharge (PD) detection in GIS switchgear. Developed to work seamlessly with the UltraTEV Plus², this sensor improves the accuracy of condition monitoring for gas insulated switchgear, ensuring safer, stronger, and more reliable high-voltage networks.
Partial discharge is one of the earliest indicators of insulation weakness in high-voltage equipment. Left undetected, PD can lead to costly failures and unplanned outages. By integrating the Barrier Spacer UHF Sensor into your monitoring regime, you gain a complete, portable, and highly sensitive detection tool for proactive asset management.
Why Choose the EA Technology Barrier Spacer UHF Sensor?

The compact and lightweight design makes it easy to move between GIS bays. This is particularly useful for routine PD surveys across large substations, saving both time and effort. - Sector-specific applications
The sensor is widely used in electricity transmission and generation sectors where EHV/HV gas insulated switchgear dominates. Its design ensures robust performance in demanding environments. - Fully integrated detection suite
When combined with EA Technology’s HFCTs (High-Frequency Current Transformers), Contact Probes, and built-in UHF sensors, the Barrier Spacer UHF Sensor delivers a full suite of PD detection tailored for GIS assets. - Advanced technology
Independently tested against rigorous industry standards, this sensor provides superior sensitivity. It reliably detects both surface activity and floating particles within gas insulated switchgear, giving engineers confidence in the results. - Seamless integration with UltraTEV Plus²
Data collected by the sensor is automatically transferred via Managed Surveys to a cloud-based platform, providing simple access, storage, and reporting for long-term condition monitoring.
Applications of the Barrier Spacer UHF Sensor
- Installs directly on cable ground straps for PD testing
- Suitable for periodic inspections and continuous monitoring
- Detects and locates PD activity within both cables and GIS switchgear
- Provides on-device sound and data recording for evidence and traceability
By combining portability, precision, and powerful analytics, the EA Technology Barrier Spacer UHF Sensor ensures that operators can detect issues before they escalate, reducing the risk of costly failures.
Understanding GIS Switchgear
GIS switchgear (Gas-Insulated Switchgear) is widely used in modern power systems because of its compact design, reliability, and ability to operate in harsh environments. Unlike traditional air-insulated switchgear, gas insulated switchgear uses sulphur hexafluoride (SF₆) gas as an insulating medium. This allows the equipment to remain compact, making it ideal for urban substations and areas with limited space.
The benefits of GIS include:
- High reliability and low maintenance
- Reduced footprint compared to air-insulated alternatives
- Enhanced safety due to sealed construction
- Long service life with minimal environmental influence
However, GIS is not immune to insulation deterioration. Detecting PD activity early is essential, which is why advanced tools like the EA Technology Barrier Spacer UHF Sensor are critical in maintaining operational safety and extending equipment life.
❓ Frequently Asked Questions (FAQ)
Q1: What is partial discharge (PD) and why is it important?
A. Partial discharge is a small electrical spark that occurs inside insulation defects. Over time, it can grow and cause major equipment failures. Detecting PD early helps avoid costly repairs and outages.
Q2: Can the Barrier Spacer UHF Sensor be used with other equipment?
A. Yes. It integrates seamlessly with EA Technology’s UltraTEV Plus², HFCTs, and Contact Probes to form a comprehensive PD detection suite.
Q3: Is the sensor suitable for permanent monitoring?
A. Yes. While it is ideal for periodic surveys, it can also support future continuous monitoring solutions without causing downtime.
Q4: What industries benefit most from this sensor?
A. The sensor is particularly suited for power transmission, distribution, and generation sectors where gas insulated switchgear is commonly installed.
The Takeaway
The EA Technology Barrier Spacer UHF Sensor is more than just an accessory; it is an essential tool for modern high-voltage asset management. By enhancing PD detection in GIS switchgear, it helps operators improve safety, reduce risk, and optimise the performance of critical infrastructure.
For reliable, field-proven monitoring of gas insulated switchgear, the Barrier Spacer UHF Sensor from EA Technology sets the industry standard.
