SAIEE ECC | Earthing & Lightning Protection Workshop


SAIEE-1962-V, 2 CPD credits : Category 1


Earthing (Grounding) plays a major role in all electrical power systems because of the particular influence of

earthing on the performance, protection, security and reliability of supply.

Electric utilities in different countries apply particular earthing methods depending on the particular nature and requirements of their distribution systems. For proper operation and maintenance of electric power substations it is important to understand and maintain correct earthing system in the utility substation and in industrial electrical networks

The course is intended to provide theoretical and practical knowledge that enables the participants to have an in-depth understanding of the applications, overall theory and essential issues relevant to system and equipment earthing.

Delegates will gain a detailed appreciation of the following:

• Principles, design, testing and maintenance of earthing systems and equipment

• Hazards and safety precautions associated with earthing

• Electrical safety requirements and procedures

• Lightning and the role of earthing in Lightning Protection

• Earthing and noise in electronic circuits

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.
