Bucharest, September 2011, International Conference on Condition Monitoring, Diagnosis and Maintenance (CMDM 2011):
Liron Frenkel, founder and CEO of Metrycom presented the results of the research carried out together with Alexander Levinzon, Dr.Daniel Kottick, and Dr. Roman Kuijnik of the Israel Electric Corporation on Online Wireless PD Monitoring System for Detection of Contamination over High Voltage Power Overhead Transmission Lines.

Contaminated insulators in polluted areas may lead to flashovers and outages if they are not cleaned periodically. Resulting power sags and power interruptions can cause considerable loss of capital to the industry and penalties to electric utilities, as there are numerous industries that depend upon the availability of an uninterrupted power supply. This paper presents an online wireless PD sensing system for predicting flashovers over insulator strings of high voltage transmission lines using an online wireless sensor network, and provides preliminary results from tests, which are now conducted by IEC (Israel Electric Corporation).
