EA Technology Voltage Presence Indicating System (VPIS)
The Voltage Presence Indicating System (VPIS) from EA Technology is designed to make working with medium voltage switchgear safer, smarter, and more efficient. This system provides a clear indication of whether voltage is present or absent within the equipment, helping engineers and technicians carry out maintenance with confidence.
With the latest accessory for the UltraTEV® Plus², the VPIS does more than just indicate voltage – it transforms into a powerful Partial Discharge (PD) detection tool, making routine condition monitoring easier than ever.

What is a Voltage Presence Indicating System?
A Voltage Presence Indicating System (VPIS) is a built-in safety feature in modern switchgear. Its primary role is to show if the circuit is live or dead, protecting operators from accidental contact with energised equipment. By integrating with the UltraTEV Plus², the VPIS goes further, turning into a highly functional PD sensor that supports early fault detection and condition-based maintenance strategies.
Key Benefits of the EA Technology VPIS
1. Reliable and Consistent Measurements
The VPIS accessory establishes a direct phase relationship with the circuit. This ensures that every reading is consistent and reproducible at the same point of measurement. Over time, this allows you to build accurate trending data, which is vital for spotting early warning signs before they develop into costly equipment failures.
2. Improved Efficiency
With the VPIS accessory, PD activity is identified quickly and reliably. This reduces the amount of time spent on-site and supports back-office analysis by providing high-quality, consistent data. The result is faster, more targeted maintenance that improves network reliability while lowering operational costs.
3. Seamless Integration with Cloud Platforms
Results gathered by the VPIS accessory can be transferred directly to EA Technology’s UltraTEV Managed Surveys cloud platform. This enables secure storage, easy access, and expert analysis of your PD survey results. The fully managed solution means you can track condition data across your entire asset base in one place.
4. Simplified PD Surveys
Traditional PD surveys often require repositioning sensors to capture accurate data. With the EA Technology VPIS accessory, this process is simplified. Just plug in, measure, record, and move on. No need for complex setups – surveys become faster, safer, and more repeatable.
How it Works: Step-by-Step
- 1. Connect the UltraTEV Plus².
- 2. Plug in the VPIS accessory.
- 3. Measure, review, and record the data.
- 4. Synchronise results with the cloud for ongoing analysis.
This simple workflow enables you to complete surveys with minimal disruption, saving valuable time and resources.
