Partial Discharge Slide

The UltraTEV Plus+™ is the leading instrument for assessing and comparing substation asset condition; providing a low cost, easy to operate system with immense flexibility.

The unit is able to detect partial discharge via TEV and ultrasonic measurement techniques to provide the user with the optimum information on the health of their electrical equipment. The capability of the UltraTEV Plus+™ has been increased with the integration into Viewsafe and the production of the Partial Discharge Maintenance Slide. By designing a Maintenance Slide that allows the ultrasonic acoustic sensor a direct line into the electrical cabinet under inspection, the UltraTEV Plus+™ ultrasonic readings are found to be up to 10x more accurate than current measurement techniques provide.

Safety regulations mean that at present on-line ultrasonic detection must take place outside of the electrical cabinet. This leads to the distortion of obtained readings via noise interference in the surrounding area; thus potentially resulting in the unsuccessful detection of faults. Viewsafe provides the perfect solution to this problem with the Partial Discharge Maintenance Slide.

The lightweight, ergonomically designed hand set features a menu-driven, backlit colour LCD screen that provides a range of information, including numerical values for TEV and ultrasonic readings. This allows operators to compare readings between assets as well as compare single asset readings over time. The UltraTEV Plus+™ also includes a headphone socket for audible readings of ultrasonic activity to enable operators to hear PD activity directly as they undertake their asset condition surveys.

The UltraTEV Plus+™ PD Detector is essential for:
• Identifying and investigating asset faults • Ensuring personal safety around MV/HV assets
• Comparing PD activity between assets
• Comparing PD activity in single assets over time • Gathering data for asset condition registers
