Abstract: 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.

The 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.

Over 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.

OMICRON Canada Protection Symposium

Tuesday, August 9th, 2016

The OMICRON Canada Protection Symposium (CPS) 2016 will take place at Hilton Toronto/Markham Suites Conference Centre on September 7-8, 2016 in the Greater Toronto Area.

Day & Time: September 7-8, 2016

Location: Hilton Toronto/Markham Suites Conference Centre & Spa
Markham Ballroom

Interesting presentations on protection, control and automation shall be presented by 15 Industry Experts. Two of the presenters are IEEE Fellows—Wanda Reder who is Chief Strategy Officer of S&C Electric and past President of IEEE PES, and Alex Apostolov who is Editor in Chief of PAC World Magazine and an industry expert on Protection, Automation, and Control. The symposium also aims to provide a platform so participants can share their knowledge and experiences on the latest developments and trends of the power industry. One of the highlights of the conference will be a tour of GE Energy’s Grid IQTM Global Innovation Center in Markham.
