Dear IEEE Student Members. As a benefit to you, we are offering 6 students the chance to participate in a power engineering tutorial worth $200 at the POWERCON2016 conference being held at the Novotel on Wed the 28th of September. If you would like to take up this opportunity please register at: https://www.surveymonkey.com/r/Q6Y6JGB. Note that volunteers for the conference will have first choice, followed by a first come first served sequence. You must register by midday Monday.
Tutorial 1 (Full day) : Smart Condition Monitoring of Power Cables with Case Studies
Electrical utilities are facing a nerve-racking problem: the continuous increase of aged electrical plant population. The breakdown of a power cable or its accessories may prove expensive for utilities and their customers. It is therefore vital to assess the condition of power cables and apply advanced techniques to reduce the failure rate. Based on the instructor’s book “Condition Assessment of High Voltage Insulation (IET Press 2008)” and the Editorial “Smart Condition Monitoring (IEEE EIM Sept/Oct 2013)”, the course is designed to provide a thorough coverage of up-to-date technology on insulation condition monitoring and incipient fault diagnosis of power cables. Focus will also be put on modern maintenance strategies and case studies which will be beneficial for power industry.
Module 1 – Introduction
Insulation materials utilized in power cables
Cable structure and insulation design
Electric stress distribution and stress control
Module 2 – Advanced condition monitoring techniques for power cables
On-line and off-line partial discharge detection techniques
VLF and OWTS tests with PD mapping
Distributed temperature sensing
On-line remote oil pressure monitoring
DGA for oil cables
Smart condition monitoring
Module 3 – Case studies
A new test and management strategy for distribution cables which reduced the failure rate to one third.
The failure of a 66kV cable was due to the damage of a sinking earthing rod 5 years ago. Why insulation tests over this period could not detect the defect?
Failures of two 230 kV cable joints due to poor workmanship.
A new 230 kV cable terminal failed after commission for only 10 days. What is the root cause of the failure? How to prevent such failures?
The causes and mitigation techniques for hot spots in two 230 kV cable circuits.
The failures of three 230 kV cables due to a design problem – lessons learnt.
Charles SuProf. Charles Su received his MEng in 1981 and PhD in 1990 (UNSW, Australia). He was a tests and operations engineer from 71-78, an honorary research associate at the University of Western Australia in 85 and a lecturer at the University of New South Wales from 90-91. From 1992-2002, he was with Monash University working as an associate professor and the head of High Voltage and Insulation Condition Monitoring Group. In 2002, he took up the chief technologist position at a large utility. From 2007 to 2011, he was a professor and chair of Research Committee at the Petroleum Institute in UAE. He was a guest professor at Beijing Electrical Power University in 2012 and a guest professor at Wuhan University in 2013. He was also an adjunct professor at Monash University, Australia. Currently, he is with Newcastle University, UK.
Prof. Su has published two books and over 180 journal and conference papers. He received the Vice-Chancellor’s Special Commendation for Teaching Excellence at Monash University in 2001 and an IEEE Standards Award for his contributions to the Guide on Partial Discharges in Rotating Machines in 2002. His research projects were funded by Australia government and industry for more than $2m. He has provided consulting services to many utilities in the world and conducted a number of training courses for the industry in Australia, Singapore, UAE, China, Malaysia, Taiwan, Hong Kong and Indonesia. He is a Fellow of IET (former IEE) and a Senior Member of IEEE since 1991.
