HV UNDERGROUND POWER CABLE RATINGS CALCULATION

Delivery:  Online Seminar (Live Streamed via ZOOM)

25-26 November 2021, 10am-6pm AEST

Seminar Overview

Transmission and Distribution Cables have long been around and have been sized very conservatively in the past, with many existing installations requiring replacement, recalculation, resizing and re-location. For both an existing installation replacement/upgrade, or for a new installation, calculating the power transfer capability i.e. the cable ampacity (or rating) of a cable system is ultimately the most critical part of designing or specifying the cable sizing, construction and configuration for continued operation.

Analytical methods 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. Australian Standards AS/NZS 3008 – HV Cables, and AS/NZS 5033 – for PV Array DC Cabling are considered in this seminar.

This seminar covers the basic technical concepts related to cable ampacity including:

  • Cable Types and Components
  • Cable and trench configurations
  • Soil and backfill characteristics
  • Thermal and soil resistivity influence and testing procedures

This background is the basis for a presentation on the analytical methods for performing ampacity calculations, and important constraints to be considered, and includes worked examples that will be discussed and presented in this seminar.

  • Important considerations for calculating the ampacity (or rating) of underground cable systems
  • Principals and Methodology of Cable selection and rating

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).
