SUMMARY:Damped AC Partial Discharge Testing for Medium Voltage Underground Cables
DESCRIPTION:Friday April 28\, 2017 at 10:00 a.m. Philipp Legler will be presenting “Damped AC Partial Discharge Testing for Medium Voltage Underground Cables”. \nDay & Time: Friday April 28\, 2017\n10:00 a.m. – 12:00 p.m. \nSpeaker: Philipp Legler \nLocation: Megger\, 550 Alden Rd\nMarkham\, ON L3R 3L5\, Canada \nContact: Ali Naderian \nOrganizers: IEEE DEIS Toronto Chapter Event \nAbstract: Partial discharge (PD) measurements are increasingly used as a reliable and non-destructive diagnostic method for detecting weak spots in the insulation of underground cables. Partial discharge measurements are also routinely used in laboratories for testing cable reels prior to commissioning and in the field to verify installation quality. \nThe most important factor to consider when choosing a test frequency is that the partial discharge characteristics at the new frequency must be like those at 50/60 Hz\, otherwise the results cannot be reliably interpreted. This is especially true when measuring partial discharge inception voltage (PDIV)\, the voltage at which partial discharge first occurs. \nOver the past 10 years\, the damped alternating current (DAC) technique has been established as a very effective method for partial discharge testing. This method is one of the voltage shapes listed for PD testing in IEEE 400.3: “Guide for Partial Discharge Testing of Shielded Power Cable Systems in a Field Environment”. In this presentation\, the concept of DAC PD test will be discussed and some practical examples will be presented.
