MORE than 150 people have been evacuated after an explosion at a NSW power station.

A large transformer exploded at Vales Point Power Station at Mannering Park near Newcastle about 10.25am (AEDT), authorities said.

Another transformer was under threat, NSW Fire Brigades spokesman Phil Turnball said.

"We're standing by waiting until the energy company can shut down the power until we can go in," Mr Turnball said.

"We can't get close to it."

He said fire fighters were cleaning up oil leaking from the power station.

There were no reports of any injuries.

'Come clean' about power station - Opposition
November 08, 2006 03:25pm
Article from: AAP

THE NSW opposition has questioned whether dividend demands on Delta Energy have led to maintenance shortcuts at Vales Point power station, where a major explosion and fire occurred today.

Opposition Energy spokeswoman Peta Seaton said the Government took $790 million in electricity dividends last year and would take $744 million this year from Delta Energy and other power utilities.

She called for a response from Energy Minister Joe Tripodi following today's fire at the Central
Coast power plant, which was evacuated while the blaze was brought under control.

"Joe Tripodi must come clean about any effect this will have on energy supply security in NSW and whether sufficient money was available after dividend payments to do necessary maintenance and protect staff safety,'' Ms Seaton said.

"Now is the time for Labor to come clean about what effect this explosion and evacuation will have on likely summer blackouts for NSW families and businesses.''

A report by Transgrid in May this year predicted reliability issues in meeting the continued increases in NSW summer peak demand, Ms Seaton said.

"This fire risks putting a hole in 10 per cent of NSW's power supply, increasing the risk of blackouts,'' she said.

Ms Seaton said Vales Point contributed about 10 per cent of NSW's power capacity.

Comment is being sought from Mr Tripodi.

Thank you, Alan.

Here in "The States" we have a group of folks called the "Amish." They eschew modern life, getting by without electricity, telephones, TV, or the internet.

I do wish that every Chicken-Little 'sky is falling' hysterically critical report (no power, not enough power, too much power, unsafe power, etc.) were balanced by a shot of an Amish farmer saying "Vat ees zee problem?"

Why did it blow up ?

Possibilities which could have caused it.

1. Sustained continuous overload, and not monitoring oil temperatures and winding temperatures.
2. Buch holz alarms, faulty which is rare but could be because of lack of maintenance.
3. No oil samples taken over a longer period of time. ( In NZ it is practise to take oil samples twice a year ).
4. Oil pump not working, should raise an alarm to network control.
5. Forced air ventilators not working.

It is interesting that these events just happen. If equipment is monitored and maintained a transformer will give early warnings that there are problems ahead.

just my $0.02 worth to this topic

Only because of this trend of every building having to be air conditioned. People seem to be too precious these days to deal with anything over 25 degrees.

PS sorry about the double post...they're experimenting with internet censorship at work now "for reasons of staff accountability" and strange things are happening
