EA Technology UltraTEV Plus2

The UltraTEV Plus² is the latest advancement in the award winning UltraTEV™ range. This easy to use instrument incorporates additional sensing capabilities and real time advances analytical features enabling you to distinguish between true PD, noise and other interference allowing you to make better decisions while saving time and money and enhance the safety of your staff and your network.

The UltraTEV Plus²guides you through the detection and analysis of Partial Discharge

The UltraTEV Plus² has been designed to make asset inspection easy. Using expertly designed classification algorithms the UltraTEV Plus² is able to help the operator understand the results, interpreting the data and displaying clear results on-screen so engineers know immediately the condition of the asset they are inspecting.

Capture results and transfer them easily

The UltraTEV Plus² can transfer asset measurement results directly to your PC or business network via USB, cable or SD Card. Together with this, the new survey functionality allows details of the substations and assets to be entered on the screen and guides people through a simple survey process.

Benefits of the UltraTEV Plus²

Multiple sensors for comprehensive assessment

There are multiple types of PD (internal, surface, corona), different types of assets that we may wish to test that can operate at a range of voltages. To deal with these variables, the UltraTEV Plus² has the capability to use multiple measurement techniques and utilize a range of sensors to allow comprehensive testing of diverse assets and detection of PD.

Ultrasonic (airborne Built-in, Flex Probe, UltraDish and Contact) for surface PD
TEV (transient earth voltage) for internal PD
UHF Antenna for surface and internal PD
HFCT for cable PD
Environmental (ambient temperature and relative humidity)

UltraTEV Plus² Locator probe

The UltraTEV Plus2 Locator probe accessory has been designed to attach to the UltraTEV Plus2, ensuring that all your PD needs can be catered for in one instrument.
The Locator probe is used in conjunction with the UltraTEV Plus² TEV sensor to locate the source of PD activity, using time-of-flight measurements.
Advanced software enables the instrument to easily locate PD at multiple discharge sites.

UltraTEV Plus² Cable PD

PD activity in cables is measured by attaching the split-core HFCT accessory around the cable earth ground. The results are displayed on the instrument in pico Coulombs (pC) as numerical values.

UltraTEV Plus² UHF Directional Antenna

The UHF Directional Antenna accessory for the UltraTEV Plus² is uniquely effective for detecting and locating PD activity in open terminal switchyards. It is also a highly effective instrument for detecting PD problems in cable joints and sealing ends. The antenna is very compact and is specifically designed for safe use inside electrical switchyards. As the antenna is highly directional with a selectable center measurement frequency it can easily be employed as a first pass safety tool for switchyard entry. It can also be used for surveying and pinpointing individual sources as part of a full site survey.

The instrument can be tuned to avoid other interference related frequencies within the switchyard and will ignore non-destructive corona discharge activity. With its unique ability to detect internal partial discharge activity in high noise environments it complements the use of the UltraTEV Plus² and UltraDish.
