i do now know what the substation voltages are, but one of the two transformers is completely burnt, and i guess they isolated the substation in order to fight the fire
In the old days, the AVR (excitation controller) was supplied loose by the generator manufacturer for others to mount in the switchboard.
This was because the old components (valves transistors) were not capable of accepting the vibration of a generating set.
Technology has progressed, and...
Dual fuel diesel engines used to be common on UK and other sewage works.
Started on diesel then added gas, reducing the diesel flow to about 10% of COP fuel flow. This diesel was the pilot fuel to ignite the gas / diesel mixture. In simple terms the gas was bled into the engine air inlet, so no...
Did the turbine go into idle, just ran near synchronous speed expecting a re-synchronisation?
is there a clutch between turbine and generator, so the turbine was not connected to generator?
First thoughts:
1. the view shown is an isometric, often used to show general details, not specifics. For these you need to to see the traditional Orthographic Views (google it.)
2. I suspect that the letters are not from Engish, but looking at the generator, i suspect they mean:

"It's my impression that railroads in England must fence their right of way."
Only since the 1845 Railways Act! Prior to that they may have been unfenced (before my time...)
I think that this applies to 'land designated as a railway' since any land that has been a railway has to be...
Most traditional prime movers (steam turbine, hydro turbine, diesel engine, gas engine etc) are essentially 'flat rated' against changes of combustion inlet temperature.
Gas turbines are not and can produce more power as inlet temperature drops. To match power in the traditional way, you have...
The generator set needs commissioning.
60 kw is very small to have the controls and engineering required to operate mains parallel.
Do you have to have permission from your electrical utility to do this?
The costs and hassle of this usually dissuade small generators from paralleling unless...
Surely what is being discussed is similar, if not identical to 'breaker fail philosophy'?
Breakers can fail to operate for a host of logic failures.
Protection relay systems can fail to operate for similar reasons.
We had a mines gas powered small power station in UK midlands, it comprised 3...
