EA Technology Wireless Phase Reference
- Perfect for phase resolved partial discharge analysis / phase resolved partial discharge pattern analysis
The EA Technology Wireless Phase Reference is a vital accessory designed for use with the UltraTEV® Plus² instrument. It enables engineers to carry out fast, reliable, and accurate partial discharge (PD) analysis across high voltage systems. By providing a stable and accurate phase lock, it ensures that PD data can be distinguished from background noise, making condition assessment far more precise.
Partial Discharge is one of the most common early indicators of deterioration in high voltage insulation. Left untreated, PD can develop into dangerous faults, unexpected outages, and costly downtime. The Wireless Phase Reference provides engineers with a straightforward way to capture clean, phase-locked data, ensuring potential risks are identified before they become serious issues.
Why choose the EA Technology Wireless Phase Reference?
A Phase Reference is critical when analysing PD in substations, cables, or switchgear. Without a phase lock, the data may appear as random interference. With a phase lock, engineers can clearly see and interpret PD activity, helping them make informed maintenance decisions.
The EA Technology Wireless Phase Reference has been engineered to deliver dependable results in any environment. It ensures the perfect phase lock through multiple sensing methods, making it versatile for different site conditions.
Key Features and Benefits:
- Multiple phase lock options – Achieve reliable phase reference via:
- Mains power connection
- E-field detection
- Rogowski coil sensing
- Photosensor (locks to fluorescent lighting)
- Wireless operation – Connects seamlessly to the UltraTEV® Plus² from up to 40 metres away, giving engineers greater flexibility on site.
- Long battery life – Up to 16 hours of continuous use, making it ideal for extended site surveys.
- Improved safety and efficiency – Helps engineers identify PD accurately without misinterpreting background noise, reducing unnecessary maintenance and avoiding costly outages.
- Compact and portable – Lightweight, easy to carry, and built for tough substation environments.
How it improves PD surveys
Using the EA Technology Wireless Phase Reference transforms PD testing:
Without phase lock: Data looks inconsistent and can be mistaken for electrical noise.
With phase lock: True PD activity is revealed, enabling engineers to pinpoint potential insulation faults quickly.
This not only increases diagnostic accuracy but also gives asset managers confidence in making evidence-based decisions to extend equipment life and prevent failures.
Applications:
The Wireless Phase Reference is suitable for use across a wide range of high voltage assets, including:
- Metal-clad switchgear
- Cables and cable terminations
- Transformers
- Overhead line equipment
By integrating the unit with the UltraTEV® Plus², users gain a complete toolkit for detecting, measuring, and understanding PD activity.
↑ Data without Phase Lock: Looks just like noise!
↑ Data with Phase Lock: PD can be easily identified
