Workshop 1: 8.30am - 12.30pm
From Grid to Chip: A Review of UPS Technology and Power Systems for Critical Loads

Workshop 2: 1.30pm - 5.30pm
Power Quality and Earthing: Problems & Solutions

Most microprocessor based loads in IT and Industrial applications require power quality that often exceeds that available from the grid. The cost of lost data, production, or even customers has to be offset against the cost of installing protected and secure power systems.

This workshop will introduce the audience to the UPS topologies of line-interactive and double-conversion as well as the available technologies: Static with battery or flywheel support; Rotary with battery or flywheel support; and Diesel-Rotary.

The electrical performance, accommodation requirements and reliability of the various systems will be covered in depth - as will the options of high-availability power system designs including static transfer switches.Both battery system design and diesel-generator to UPS interfaces will be examined.In conclusion the relationship between availability of critical power and Maintenance (including 'concurrent maintenance') will be covered.

This workshop commences with a review of the fundamentals of power quality and EMC and then examines the procedures for design and installation for earthing and neutral systems. Power quality, harmonics, earthing, surges & noise for electrical & electronic systems are detailed in the half day session, which is then rounded off with realistic case studies covering a wide variety of industries ranging from manufacturing and process control to telecommunications.

At the end of this workshop participants should be able to:

• Gain a working knowledge of the basics of earthing and harmonics
• Understand transient protection and harmonics
• Understand essentials of electrical and electronic systems
• Isolate and rectify simple power quality problems

Ian Bitterlin - Vice President, Active Power MIEE, BSc, PG Dip(DI)

Ian commenced his engineering career with a focus on electrical drives (Schindler & Mannesmann) in a design capacity. Since then he has worked in various leading organisations in the areas of static, rotary and diesel UPS's, static transfer switches, TVSS's and automatic transfer switches. Currently a Vice President for Active Power, who are leaders in battery free UPS technology utilising flywheel or compressed air as energy storage media. Recently he co-authored two sections of the CIBSE Electrical Guide on UPS and HV Switchgear. He has presented numerous papers and courses throughout the world on drives, UPS's and critical power applications. Ian is an entertaining and knowledgeable presenter.

Terry Cousins - Motswedi TLC Software, South Africa

Terry has a BSc in Electrical Engineering, a bachelor of commerce and master of business leadership degree. In 1988 Terry co-founded TLC Software with two colleagues. The company’s objective was to develop and sell engineering software solutions for the industrial market. Terry was involved in the design and development of TLC Software’s power quality instrument, the QSR2000, used by ESKOM (electrical utility), MTN (cellular telephone operator), ISCOR (iron and steel), Columbus Stainless Steel (steel manufacturer), Rand Water Board (water utility) and many industrial companies and municipalities. The QSR2000 is also being exported to Brazil.

Terry is on the South African Bureau of Standards committee for power quality instruments (SABS 1816:2000), which is revising the current South African national power quality standard. As a senior member of the South African Institute of Electrical Engineers Terry has authored several papers on power distribution and power quality for local and international magazines.
