Second HV network survey completed for 180 terminations.
Second HV network survey completed for 180 terminations
Prysmian has recently completed a second comprehensive HV network survey for Hydro-Québec in Canada using Prysmian Group’s exclusive Pry-Cam Portable. Hydro-Québec – government-owned public utility that oversees generation, transmission and distribution of electricity for all of Quebec –, has chosen to partner with Prysmian Group for this new survey (the second), involving on-line partial discharge measurements of 180 HV terminations.
Pry-Cam Portable is a small, high-performance PD acquisition system, specifically designed for on-line measurements. It includes a patented wireless electromagnetic sensor for PD signals detection and phase synchronisation, a digital acquisition system and a WIFI interface.
Pry-Cam Portable is accurate and easy to use: by simply pointing it at the electrical component to test, it is immediately able to stream PD data to a PC or tablet wirelessly. Thanks to the exclusive Pry-Cam technology Prysmian Group can provide a reliable and accurate diagnosis within few minutes.
Hydro-Québec has used Pry-Cam Portable to promote, support and implement the concept of Predictive Maintenance within their organisation. According to Roberto Candela, CEO of Prysmian Electronics, “The results were so satisfying that the Canadian company presented the HV networks survey and its results as a successful case study to the Transmission Underground Cables Interest Group (TUCIG) at the CEATI (Center for Energy Advancement through Technological Innovation) conference, which took place in March 2014. It was a pleasure for us to be mentioned in this context by such an important customer and we trust this solution will soon be recognised in the entire North American market as the best solution for PD measurements.”
During the conference, Hydro-Québec underlined the necessity of having an accurate, flexible and fast PD instrument for on-line measurements during normal operation. When comparing Pry-Cam Portable with the other instruments tested, they stressed the false positives often obtained with the latter. “Pry-Cam Portable was always able to measure very small partial discharges without the false positives produced by competitors’ devices” ended Candela.
