HIGH VOLTAGE TESTING & MEASUREMENT

SAIEE-1906-V, 2 CPD credits : Category 1

1. OVERVIEW

 

Insulation plays a vital role in high voltage systems and a good understanding of the role of the different insulation materials used in high voltage systems is essential.

The aim of this workshop is to discuss the basics of air, solid and liquid insulation in order to understand the need for testing and the limits of test voltages and currents applied to the different insulation materials. The advantages and disadvantages of testing with DC, Power Frequency and very Low Frequency AC voltages will also be discussed. A further need is to test the insulation with impulse voltages to determine its ability to withstand lightning induced surges. Evaluation of the condition of insulation is very important and diagnostic evaluation form a major part in testing of high voltage insulation. Two major components of high voltage systems are transformers and cables. Specific attention will be given during the workshop on the testing and evaluation of these two components.

PRESENTER

 

Prof J.J. (Jerry) Walker DTech

After completing his National Higher Diploma in Engineering (Electrical) in 1986 and spending almost 23 years in industry, Prof Walker joined Vaal Triangle Technikon - now known as Vaal University of Technology (VUT) as a lecturer in the Dept. of Power Engineering. In 1996 he completed his BTech degree and in 1997 started with post graduate studies, specialising in diagnostic testing of XLPE-insulated cables. In 2004 Prof Walker completed his DTech degree at VUT. Title of his Doctoral thesis: “Diagnostic Evaluation of Water Tree Aged XLPE-Insulated Cables”. In 2005 he was appointed as Associate Professor at VUT and then as Head, Institute for High Voltage Studies. He retired from VUT in 2006.

Presently Prof. Walker is:

• Director of his own company: WALMET TECHNOLOGIES (PTY) LTD

• Visiting Professor at VUT managing Research and supervising Post Graduates in Power Engineering.
