  1. A time-sequenced presentation of the history of the national grid Stuart Nicholson Tony Silke Richard Donaldson A presentation to the Engineering Heritage Workshop, Wellington August 2004

  2. What is the national grid? • Transmission of electric power • from large power stations • to line companies, and • to large industrial users. • Includes the HVDC link.

  3. Who are we? • Electricity Transmission Heritage of NZ Inc • Collecting and making available resources for study of the historical development of the New Zealand electricity transmission system • Membership mainly drawn to date from Transpower staff, contractors, and consultants • Strong sponsorship from Transpower executive • Gathering also from non-transmission sources

  4. How to tell the story? • Depicting grid development • The grid has grown from 1915 to today and is continuing to develop • We have collected data going back to the beginnings • A visual display of this growth • Use Power Point to give one slide per year?

  5. Source material • Network drawings & maps from Transpower record system • Records of all circuit-breakers and power transformers • Histories (see references)

  6. Network drawing sample c. 1925

  7. Network on NZ map from 1940s

  8. Network drawing sample

  9. A first mock up to demonstrate the concept

  10. OAM HWB Otago joined to Canterbury 1935

  11. BWR AHA COL GOR HWB Southland joined to Otago & Westland joined to Canterbury. Diesel ex-LYT at DOB DOB ALD 1938

  12. EDG ARI DOB AHA MST UHT BOP joined to NI Grid & WC Generation joined to SI Grid Assume UHT not yet connected to KHD 1939

  13. KTA MPE PEN PAK ARI KTA joined at 50 kV to Wairua Falls generation near MPE. Reinforcement of supply to Auckland from ARI 1940

  20. Things we learnt • Finding accurate information is essential • Attracting attention to the display • Social commentary • Relate development to the era • Show relationship of development to history

  21. On display at the Linemen’s reunion 22-24 November 2002

  22. Learnings from this version • Not eye-catching • Slow moving • Minimal commentary • Minimal relating to NZ historical events and social developments • Not suitable for a public venue

  23. Transpower interest in its use • For training • The move to Transpower House • Public appeal – www. • Offer to develop with professional assistance

  24. Origin Design input • Using Flash instead of PowerPoint • Interactive • www compatibility • Plasma display in foyer of Transpower House • PC file also provided • Style

  25. Run some of D:\Grid Preso Flash\normal.exe

  26. Drivers for ETH • Database record • Social comment • Offering value to Transpower • Our patron • Funding • Name/status/recognition for ETH

  27. Application elsewhere • National highway • Railways • Telecom network • Ports & coastal shipping • Water supply on a regional basis

  28. Characteristics of the display • Visual • Time-sequenced • Map-based • Auto or manual operation • Source files can be more detailed • Can be put on the web (www)

  29. Who benefits? • Transpower as a corporate citizen • ETH output • Engineering research tool/database • Reunions – stimulus to memory • Highlights gaps in knowledge!

  30. References • Transpower drawing records system • Transpower equipment record files • NZED equipment database conceived, prepared, and maintained by Ron Jane on the “Vogel Computer” • White Diamonds • (Power board history) • Power Politics & People

  31. Acknowledgements • Transpower • Hayley Grace • The Linemen’s Reunion • Origin Design
