Seminar Overview

Seminar Leader’ s Profile

Temporary overvoltages are common to power networks and systems. However, it is paramount for electrical power

engineers to reduce the number of outages and preserve the continuity of electricity service and supply. It is therefore

necessary to direct special attention towards protection of transmission lines, substations, power plant and equipment

from the major causes of overvoltages in power networks and systems such as lightning and switching overvoltages.

This seminar provides attendees with an overall understanding of issues or damages that overvoltages on the system

may cause to plant and equipment, as well as a practical appreciation of the various methodologies employed to

reduce such damages. This seminar will cover important aspects relating to insulation coordination including

principles of insulation coordination, methodologies used, identifying insulation strength, causes of overvoltages and

mitigation of hazardous overvoltages. Further, this seminar will also focus on numerical analysis, modelling and

implementing insulation coordination steps and techniques, which involves application of a set of quantitative

procedures including:

¨ Analysis and modelling of the operating voltage under normal conditions

¨ Selection of rated impulse withstand voltage of plant and equipment

¨ Calculation and modelling of temporary overvoltages, switching overvoltages and lightning overvoltages

using empirical calculations and transient software modelling

¨ Design, location, and selection of surge arrestors

¨ Mitigation methodology including shielding of overhead lines and substations

Hence, achieving the best possible technical and economical design for protection of persons and equipment

against overvoltages.

Malcolm is currently a Technical Principal at SMEC (Snowy Mountains Engineering Corpora-tion). He is a recognised specialist in Substation Design, Insulation Co-ordination and Earthing of Power Systems, both in Australia and internationally. Malcolm provides post-graduate professional development training on topics associated with power systems, with specific reference to Substation Design.

With over 40 years working experience in the electricity transmission and distribution industries. During this time , Malcolm has personally investigated and managed the risks as-sociated with substation design, insulation co-ordination, earthing, lightning protection and interference. He has been involved in design, mitigation and implementation of insulation co-ordination schemes associated with Australia ’ s electricity transmission and distribution networks. Malcolm has held various responsible positions in the Electrical Engineering discipline, consulting, design, project management, maintenance of power systems and has a special interest in studies for network connections, insulation co-ordination, power system augmentations, detail design, layout and refurbishments, covering primary, secondary and protection systems.

Malcolm has worked on projects for the power generation, transmission, distribution, traction, mining and heavy industries in a variety of commercial project and design management roles, with primary responsibility for substation design, installation and commissioning and has practical knowledge and experience working with LV, HV to EHV systems, renewables and switchgear systems, with extensive experience in electrical substation design, protection systems, HV cabling designs, transformers, NER/X ’ s , capacitor banks and reactors, PLC ’ s , frequency drives and large motor control systems.

Malcolm is a Member of the Institute of Engineers Australia, a Chartered Professional Engineer, a Registered Professional Engineer of Queensland. He holds a Master of Engineering Science (Power Supply Engineering).
