The UltraTEVTM Plus2 brings together techniques and a wealth of experience and insight to make it easier than ever to avoid failures on your high voltage network.
This latest hand-held Partial Discharge (PD) instrument is easy to use, and combines additional sensing capabilities with real time advanced analytical features. The ability to distinguish true PD from noise and other interference means that you can make better decisions, save time, money and enhance safety.
User Features
Provides numerical and audible ultrasonic readings for classification of PD
Provides numerical and audible TEV readings for interpretation of PD
Use the Locator probe accessory to accurately locate multiple PD sources
Use the High Frequency Current Sensor (HFCT) to detect PD activity in cables
Phase resolved and waveform displays allow more reliable and conclusive decisions to be made based on measured PD
Wi-Fi connectivity allows survey results to be easily synchronised with asset management systems Use NFC tags attached to the assets to store and retrieve key results
Menu-driven backlit colour touchscreen and buttons (can be used when wearing gloves) giving an intuitive user experience
Capturing the results and transferring them easily:
The UltraTEV Plus2 has NFC capability to store Asset data on programmable tags. It also has the ability to transfer the results directly on to your PC via Wifi or USB / SD Card.
The survey functionality allows details of substations and assets to be entered on the screen, guiding users through the simple survey process. Screen shots can also be captured and saved.
Interpreting the condition of your electrical assets:
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.
Partial Discharge Detection and Advanced Analytics:
The UltraTEV Plus2 has the ability to measure PD in cables and cable accessories using an HFCT as well as established techniques for surface PD (Ultrasonic) detection and internal PD (TEV) detection on switchgear.
The new advanced analytics allow PD measurements to be examined more precisely in real time or after the inspection:
Phase plots: helps to differentiate between noise patterns and real PD
Waveform capture: examines amplitude of individual pulses, for PD Characteristics
Histograms: assists with identification of multiple sources of PD and noise discrimination
