EA Technology UltraTev Plus2 – Advanced Partial Discharge Monitor

Protecting high-voltage networks has never been more important. The EA Technology UltraTev Plus2 is a next-generation partial discharge monitor designed to give engineers and asset managers clear insight into the condition of their equipment. Portable, rugged and easy to use, this powerful tool helps identify issues before they develop into costly or dangerous failures.

Why Choose the EA Technology UltraTev Plus2?

The UltraTev Plus2 is a hand-held instrument that combines tried-and-tested partial discharge detection methods with modern digital analytics. Unlike older PD test tools, it can differentiate genuine PD activity from background noise or electrical interference. This means results are more reliable, allowing better decisions to be made on maintenance, repair, and replacement.

For network operators, early detection of PD helps avoid outages, reduce repair costs, and extend the life of critical assets such as switchgear, transformers, and cables. Case studies show the UltraTev Plus2 preventing serious failures at solar farms, ports, and major industrial printing sites.

Key Features of the UltraTev Plus2

• Dual Measurement Modes – Provides both ultrasonic and TEV (Transient Earth Voltage) readings to classify and interpret PD activity.
• Advanced Analytics – Includes waveform capture, histograms, and phase-resolved displays for accurate analysis of PD sources.
• Cable PD Detection – Uses Radio Frequency Current Transformers (RFCT) to assess PD in cables and accessories.
• Connectivity – Results can be transferred instantly via Wi-Fi, USB, or SD card, and linked with asset management systems.
• Smart Survey Mode – Guides the user step-by-step, recording substation and asset data on screen.
• User Friendly – Features a backlit colour touchscreen and keypad designed for gloved use, with multi-language options.
• Rugged and Portable – Built for tough working environments with a long-life Li-Ion battery.
• NFC Integration – Attach smart tags to assets to store results locally for quick comparisons on repeat inspections.

Kit Options

The EA Technology UltraTev Plus2 is available in different kit configurations to suit varying needs:

• Kit 1 – Switchgear Package
  Standard configuration for metal-clad switchgear assessments. Includes headset, chargers, SD card, and protective carry case.
• Kit 2 – Switchgear and Cable Testing
  Adds an RFCT sensor, ultrasonic contact probe, and flexible sensor for quick, non-intrusive cable condition assessment.
• Kit 3 – Comprehensive Asset Package
  Includes the UltraDish™ accessory for detecting PD in overhead assets, ideal for utilities and industrial sites with outdoor substations.
• Additional Accessories
  Options include the Locator Probe, UHF Receiver and Directional Antenna, NFC tags, and environmental sensors, offering complete flexibility for PD monitoring.

Business Benefits

The EA Technology UltraTev Plus2 delivers measurable benefits:

• Detect and locate PD issues before failure occurs.
• Optimise maintenance cycles and extend asset life.
• Increase site productivity by capturing condition data quickly and consistently.
• Reduce downtime by comparing survey results over time to track asset health.
• Minimise training requirements thanks to the intuitive touchscreen interface.
• Prevent catastrophic failures and safeguard business continuity.

Real-world results show that this partial discharge monitor has saved businesses from extended outages and costly equipment replacement. For example, at the Port of Felixstowe, the device helped identify PD in ageing RMUs, avoiding disruption to 44% of the UK’s container trade.

The UltraTEV^® Plus² has been designed to make asset inspections easy. The instrument helps the operator understand what the results mean by interpreting the data and displays clear information and instructions.

Case Studies in Action

• Solar Energy – At a large UK solar farm, the UltraTev Plus2 identified cable termination issues that could have caused flashover and major income loss. View Case Study
• Heavy Industry – Trinity Mirror Print used the UltraTev Plus2 to locate and confirm PD within high-voltage cabinets. This prevented failure of a critical current transformer, avoiding weeks of costly downtime. View Case Study
• Ports and Transport – At Felixstowe, ultrasonic detection pinpointed poor cable terminations and insufficient air gaps, helping maintain operational reliability. View Case Study

❓ Frequently Asked Questions (FAQ)

Q1: What is a partial discharge monitor?

A. A partial discharge monitor is an instrument that detects small electrical sparks occurring within insulation systems. These sparks, if left unchecked, can develop into dangerous failures.

Q2: Who should use the UltraTev Plus2?

A. It is ideal for utility companies, industrial sites, renewable energy operators, and anyone responsible for maintaining high-voltage assets.

Q3: How does the UltraTev Plus2 save money?

A. By identifying problems early, it prevents unplanned outages, reduces repair costs, and avoids replacing equipment before it is truly necessary.

Q4: Do I need specialist training to use it?

A. No. The UltraTev Plus2 is designed with intuitive menus and survey guides, meaning minimal training is required.

Q5: Can it be integrated into asset management systems?

A. Yes. Data can be exported via Wi-Fi, USB, or SD card and stored in corporate systems for long-term tracking.

The Takeaway

The EA Technology UltraTev Plus2 is more than just a partial discharge monitor – it is a complete solution for assessing, managing, and safeguarding high-voltage networks. With advanced analytics, flexible accessories, and real-world proven reliability, it provides a smarter, safer, and more cost-effective way to monitor critical electrical assets.
