Dr. Gulski, an IEEE Fellow, received his M.Sc. in information technology from Dresden Univ. of Technology, a Ph.D. from Delft Univ. of Technology and a Doctor Habilitatus from Warsaw Univ. of Technology. A former Professor at Poznan Univ. of Technology and most recently at Lodz Univ. of Technology, he is CEO of an organization of independent companies providing knowledge to power utilities. He has served as Chairman of 4 Cigré Working Groups and is presently Chairman IEEE Working Group PE/IC/F05W/400.4 P400.4, Chairman of IEEE PES ICC Sub G TNL and Swiss member of Cigré WG B1.38. He is author/co-author of 380 publications and 3 books on HV Diagnostics and Asset Management.
Problems with accessories and/or installation can influence the quality of a newly installed power cable circuit. While manufacturer standards recommends on ‘Go/No-Go’ decision based on simple overvoltage tests, even in a no-breakdown situation presence of defects cannot be excluded, meaning standards do not provide sufficient recommendations for after-laying testing. Damped AC voltage provides sensitive measurement of PD and dielectric losses over a complete cable circuit. This presentation discusses improving test procedures for after-laying testing and diagnostics of all types of on- and offshore power cables. Practical examples using damped AC voltages when testing new connections as well as in assessing condition of service aged cables will also be provided.
