Less than 150 women are Engineering Learning Factory (p. 34). It is a great example fellows of Engineers Australia, demonstrating the low of the new manufacturing paradigm that Australia needs numbers achieving senior positions. Unsupportive work to maintain jobs growth in this sector. I am also proud to place cultures still result in half of women engineers introduce an article by Todd Rowling (p. 32), a graduate leaving the profession by age 30 and the number of the summer school, who has completed an engineering remaining continues to fall in every decade thereafter, degree and works for Ausgrid. These articles demonstrate especially if women have children. While there is a focus the promise and the possibilities of what can be achieved to get girls interested in engineering, there is also a need if the engineering profession makes the best use of our for effective programs to genuinely support women to diversity advantage.

Power System Incident Report Trip of 8811 Calvale – Tarong 275Kv Line
POWER SYSTEM INCIDENT REPORT TRIP OF 8811 CALVALE – TARONG 275KV LINE, TARONG UNIT 2 AND COLUMBOOLA 132KV CB 73562 ON 05 NOVEMBER 2009 PREPARED BY: ESOPP DOCUMENT NO: 1.0 VERSION NO: 1.0 FINAL 1. INTRODUCTION At approximately 17:49hrs on Thursday 5th of November 2009, severe thunderstorms were experienced in the vicinity of Calvale – Tarong 275kV lines (Bureau of Meteorology - BOM issued a Severe Thunderstorm Warning) and one of the Calvale – Tarong lines - 8811 experienced a single phase trip and auto-reclose. The No.2 generating unit at Tarong Power Station (TPS) tripped from 350MW of load at around the same time. At approximately 17:50hrs, one of the 132kV feeders from T194 Columboola substation (Ergon Energy) to Condamine power station also tripped but there was no generation at Condamine power station at the time1. This report has been prepared under clause 4.8.15 of the National Electricity Rules to assess the adequacy of the provision and response of facilities and services and the appropriateness of actions taken to restore or maintain power system security. Information for this report has been provided by Powerlink, Tarong Energy, Ergon Energy and QGC Sales Pty. Ltd. Additional information has been obtained from AEMO’s Energy Management System and Market Management System. All references to time in this report refer to Market time (Australian Eastern Standard Time). 2. SUMMARY OF EVENTS At approximately 17:49hrs on Thursday 5th of November, severe thunderstorms were experienced in the vicinity of Calvale – Tarong 275kV lines. A market notice was issued at 13:47 hrs, reclassifying loss of 8810 & 8811 Calvale – Tarong double circuit 275kV lines as a credible contingency from 1345 hrs onwards.
