Well, a new year is upon us. Mayans? Nah!
Things that have happened since the last post (not in any particular order):
23rd December 2011 a Magnitude 6 earthquake occurred in the Christchurch area, initiating a swarm of quakes offshore, prompting tsunami concerns and the GNS to report the aftershocks could go on for decades. Being only 3km from the epicentre, our house received further damage, as well as thousands more. The quake was extremely violent and knocked my wife off her feet even though she was bracing herself in a doorway. Scary stuff.
Red Zones have been announced around Canterbury, in which property owners have been offered 2007 Rateable Value prices for their properties by CERA (Canterbury Earthquake Recovery Authority), a New Zealand Government Department established due to the quakes with Roger Sutton as CEO. Our own property was declared blue/green zone, which means we could rebuild, but with a stronger foundation and after a geotech report on our property's viability in future earthquakes has been compiled by a geologist. Mainzeal, our insurance companies' main contractor is apparently 'waiting for the earthquakes to stop', before commencing rebuilding.

I have given two presentations on my experiences during my Academic Study Leave (ASL), one to a joint CPIT/Canterbury Electrical Association, and one to the Canterbury Electrical Association's AGM.
I was generously invited to co-write an academic paper on 'The impact of the Christchurch earthquakes on the electrical power system infrastructure' by Professor Neville Watson from Canterbury University for the New Zealand Society for Earthquake Engineers quarterly journal. This paper was accepted for publication in December.
Professor Watson also introduced me to Professor Venayagamoorthy from The Missouri University of Science and Technology, who is a worldwide leading authority on 'Smart power networks'. I gave both Professors a tour of our Sullivan Ave campus. CPIT and I have given both Professors authority to use my ASL photos in their very valuable work. In December, Professor Watson gave me a tour of the Canterbury University Electrical Engineering department, which was fantastic!

I applied to have my ASL work classed as research at CPIT under the title 'Learning Cable Jointing and Line Mechanic work during the Canterbury earthquakes', asking the question; "What are the educational benefits of collecting and analyzing multimedia evidence of workplace skills to inform the development of new courses?". As part of this I have submitted an abstract with a view to presenting at the New Zealand Vocational Education and Training (VET) Research Forum in Wellington in April.
I attended the 2011 ESITO annual Lines Competition and Awards dinner at Mystery Creek in Hamilton with my Manager, Stephen Price.

My wife and I visited Geonet in Lower Hutt in November where we were given a fantastic tour by Sara, author of the 'Shaken not Stirred' blog.

I completed the Diploma in Tertiary Learning and Teaching 604 course 'Applied Learning Project', based on my ASL experience and written conclusions. Thanks Selena!
My wife and I attended a Connetics 'thank you dinner' at the RNZAF Air Force Museum in Christchurch we were generously invited to. It was a fantastic night dining amongst the fantastic aircraft in superb company for a superb company!

I gained promotion from 'Academic Staff Member' to 'Senior Academic Staff Member' at CPIT although one of my colleagues, who I thought would get promoted ahead of myself did not, which I was very confused and disappointed about.
So a lot of water has passed under the bridge. Poor Christchurch (and Canterbury) have been nailed again by yet another major earthquake with yet more damage, but thanks to power network reinforcing, there were few outages. The Rawhiti Substation, which replaced the sunken New Brighton substation is open now. The power reliability has been good. Not perfect, but good, which is good(?) considering the current environment.

CPIT for the rest of 2011 was 'flat stick'. Due to contractual negotiations being difficult, one of the CPIT unions engaged random strike action, which made life difficult, as all staff and students were stressed (as well as the rest of Canterbury) and emotion was high.
I have so far received no 'green light' to start development of Cable Jointing or Line Mechanic courses, however, I have been doing work on this in my own time. CPIT are in the process of employing two more staff into our department, which will hopefully help to ease the load. Unfortunately no Cable Jointers or Line Mechanics have applied for these jobs, as they seem reluctant to apply for jobs in the academic profession, as they have also done for the last 6 years, which is a shame.
In 2012 I am continuing to teach CTC (Canterbury Tertiary College) and 'Youth Guarantees' students. My Manager tells me it will be an unbelievably busy year. We have our normal courses, CTC, Youth Guarantees, and also special Maori and Pacific Island electrical students to teach this year.
My Manager also instructed me to take all my leave now, as time off during the year will not be allowed, so I'm having a big holiday now, but with no more until December 2012, which is a shame, as my wife Emma can't take any as leave her work is so busy at the moment.
I hope everybody who reads this has a prosperous 2012, and fingers crossed for Canterbury that the quakes stop and the rebuild hopefully begins soon. It has to sometime!
Finally, here's a tribute video to the Christchurch power workers I made:

Work log: Monday 21st March: Worked at North Parade, Shirley to repair a low voltage XLPE attached to a bridge for a private right-of-way that had been severely bent (but still operating ok, amazingly!) by the riverbanks 'slumping' in the earthquake 22nd Feburary. Slumping bending the low voltage XLPE Steve showing off the bent section Tuesday 22nd: QEII Drive near Marshlands Rd roundabout, XLPE-XLPE 11kV joint, network consolidation. Wednesday 23rd: Philpotts Rd near QEII Drive, XLPE 11kV termination into kiosk for network consolidation. Tightening 11kV terminations in kiosk Thursday 24th: Philpotts Rd again, more kiosk terminations and XLPE-PILCA joint. Finished kiosk terminations Friday 25th: Pages Road near bridge, PILCA-XLPE-PILCA faulty 11kV cable replacement. These rings are the modern alternative to lead wiping. Liquefaction causes the building to sink, pulling overhead connections off. Riverbank 'slumping', causing th...
Christchurch has had 3 major, 10 moderate, and around 7000 minor earthquakes and aftershocks at this point in time. The following is a personal account of the damage based on my personal experiences and the different side-effects of earthquakes. I need to stress at this point in time, I am NO geologist, seismologist, or network analyst. So some of this information may not be accurate, it's simply based on my logic as an Electrical Tutor! I apologize in advance if I say anything incorrect, and feel free to post anonymous comments (this has been done, already, thank you!) and correct me. In my opinion there have been four major side-effects of a quake (in Christchurch's case): Ground shaking Liquefaction Lateral spread L andslides/building collapse/rockfalls. Christchurch did not experience tsunami related to our own quakes at any stage. I will cover each category for some systems in the Christchurch distribution network that...
Well, I've finished with lines in the interim until later this month. In the meantime I'm going to be spending some time in 'Subs' and the 'Test room' Departments. Work log: Monday 2 May: SUBS; Brookside and Hororata Substations; repair design fault with approved manufacturer's rewire. Brookside substation Switchgear at Brookside substation Hororata Substation. The windows broken in the 4 September 2010 quake have been covered with wood. Tuesday 3 May: Wire control unit in workshop. Wednesday 4 May: Greendale Substation; Move and permanently wire communications unit. Greendale substation.. yes, it's practically on the fault line. Control units inside the substation Evidence of the explosion that occurred at the back of a circuit breaker during the M7.1 earthquake. Substation yard gates... do they line up?!! Thursday 5 May: TEST ROOM; Isolate and earth faulty 11kV cables, Opawa Rd bridge and near AMI stadium. Also rec...
