Seminar Overview

Underground transmission and distribution cables systems have lately experienced a renewed interest by the network service providers, industry and developers. Underground power cable systems are now being implemented as the preferred medium to transmit energy over reasonably long distances, specifically with the huge increase in renewables such as solar and wind farms at medium voltage levels.

This seminar covers review of the basics and later engages in the review of designs that provide lowest cost and
highest reliability systems, methodologies of uprating existing cable systems with a look at design to identify and
correct any issues that may lead to pre-mature failures.

A brief review of the various methodology used in designing and installation of such as the Neher and M.H. McGrath methodology, have now been refined by the IEC with and its development of IEC 60287 and related ampacity     standards. Other Australian Standards such as AS/NZS 3008 – HV Cables, and AS/NZS 5033 – for PV Array DC Cabling are referred in this seminar.

This seminar covers the basic technical concepts related to underground power cable systems including:

  •  Overview of cable types, components, construction and accessories
  •  Soils and backfill characteristics, thermal and soil resistivity influence
  •  Underground cable system design including:
  •  – cable and trench configurations
  •  – soils and backfill and its effects on ampacity
  • System constraints on cable ratings
  • –  multiple cable loading
  • –  temperature
  • –  Installation configuration and influence of laying conditions on ampacity
  • –  operation and maintenance
  • –  sheath bonding effects
  • –  increasing efficiencies
  • Installation methodologies
  • Condition monitoring and testing procedures

What You Will Learn?

Attendees will gain an understanding of :

Principles of cable design and accessories, methods and information on:
– planning, design and installation of underground cable circuits.

– cable system types, available design tools, cable accessories and configurations.

– system constraints on cable ratings

– all aspects of underground transmission systems, from the initial planning through design optimization  to final operation and maintenance.

– overview of cable testing and monitoring

Important considerations and requirements leading to the calculation of ampacities (or ratings) of underground power cable systems.

About the Seminar Leader

Our seminar leader is currently a Technical Principal at SMEC (Snowy Mountains Engineering Corporation). He is a recognised specialist in Substation Design, Insulation Co-ordination and Earthing of Power Systems, both in Australia and internationally. He 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, He has personally investigated and managed the risks associated 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. He 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. He 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. He 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).
