New phase lock accessory
EA TECHNOLOGY, specialist in asset management solutions for owners and operators of electrical assets, has launched a new accessory for its UltraTEV Plus² instrument for partial discharge (PD) detection.

The company says the new Wireless Phase Reference (WPR) unit makes PD data analysis easier and more accurate by helping to ensure a high-quality phase lock.
The compact and robust WPR unit connects to the UltraTEV Plus² via Wi-Fi. It offers a reliable and versatile method for providing a phase lock to match the frequency of the test instrument to the 50 or 60Hz frequency of the HV network. This allows PD events to be plotted on a phase resolved partial discharge (PRPD) display, to allow patterns to be interpreted on the first attempt at surveying, ensuring effective time management of staff.
A high quality phase lock is essential to be able to differentiate between PD and noise, as well as to enable discharges on different phases to be detected.
