EA Technology UltraTEV® Plus2 Wireless Phase Reference

A phase lock is critical to understanding partial discharge in high-voltage systems, enhancing data analysis, and optimising decision-making. The EA Technology UTP2-WPR wireless phase reference accessory guarantees an accurate phase lock in any environment.

Why you need Wireless Phase Reference with UltraTEV Plus²

• Ensures the perfect phase reference every time, through multiple methods (mains power connection, e-field, Rogowski coil, and photosensor)
• Wireless connection to the UltraTEV® Plus2, up to 40 metres away
• Long-life battery, up to 16 hours

4 ways of Achieving Phase Lock

Using EA Technology's UltraTEV Plus² with Wireless Phase Reference, a phase lock can be achieved in four different ways:

• Direct power mains connection
• E-Field - An internal sensor will detect and lock on to the stray electric fields within the substation
• Rogowski coil - Detecting AC signals in any conductor
• Photo sensor - A photo sensor on the front of the instrument will lock on to nearby mains frequency lighting such as a fluorescent fitting when there is a line of sight between the sensor and the light
