How do you synchronizing panel works?
Paralleling generatorsThe following is for three phase manual paralleling of two generators. Today's control systems will sense and do this operation automatically but the general process is the same. There are a couple of factors that have to be met when paralleling generators. The process of paralleling generators is called synchronization. What this means is that both generators have to be in phase with each other and running at the same speed. The generator that is running is called the lead generator and the one that you are trying to parallel is called the lag generator. There are two types of instrumentation used in synchronising, one is a light bank and the other a bit more sophisticated is a synchroscope meter. The synchroscope indicates whether the lag generator is faster, slower or in phase with the bus. The lag generator is brought up to speed just under the RPM of the lead generator. The synchroscope will be revolving very slowly in a clockwise rotation at this point. When the hand on the synchroscope reaches the 11 o'clock position the switch is thrown to bring the generator on to the bus tying the two generators together.
Why does the synchroscope need to be rotating clockwise if it is turning slowly counterclockwise won't that work the same?
because the incoming generator has be connected as a source and not a load to the grid. if the frequency of the incoming generator is lower than the grid frequency then ... it will behave as a motor drawing power from the grid and generator will trip in reverse power protection.

When was Hunedoara steel works created?
Hunedoara steel works was created in 1884.
How does pneumatic air gun work?
it works with compressed air
What direction must the synchroscope be travelling when the breaker is closed?
clockwise
How do you synchronized generator 1 to which is running to generator 2?
First, you must make sure that your Generator is in phase and with the same frequency.. When your Generators is the same as what I've mentioned above. Then you are ready to synchronize your Gen. Turn on the synchroscope pointing on the incoming Generator. Observe the pointer or arrow in the synchroscope, it must be turning in fast direction..adjust the speed of turn of the pointer by adjusting the governor knob..lastly close the circuit breaker(ACB), when the pointer points on 00 degree of the synchroscope, adjust the load sharing using the governor knob..

What is synchroscope in diesel generator?
a synchroscopeis a device that indicates the degree to which two systems (generators or power networks) are synchronized with each other.ayaz ahmad4th engineer
Why you close generator breaker when synchroscope needle position is between 11 and 12?
so that the incoming generator will not act as load but rather a source that can synch in less time
Steps of synchronizing steam turbine generator?
1. Turn Electronic Governor Switch on. 2. Open casing drain valves 3. Check bearing oil levels 4. Reset Over-speed Trip 5. Put bearing cooling water on 6. Crack exhaust (outlet steam header) and adjust drain valves accordingly 7. When warm crack inlet steam valve allowing turbine to run at 10rpm 8. Check bearing oil rings 9. Look for carbine seal run offs 10. When turbine is warm fully open inlet steam valve and allow governor to take control to 2200rpm 11. Use speed knob to raise speed to 3600rpm 12. Turn Field Excitation Switch on 13. Check incoming and grid voltages and match turbine generator excitation to grids voltage using the field excitation rheostat. 14. Use speed knob to reach 60hz 15. Turn on synchronization switch to the synchroscope 16. Adjust turbine speed to adjust the phase angle/frequency to a steady slow clockwise rotation on the synchroscope. 17. Close generator breaker at the 5min to 12'oclock position on the synchroscope. 18.Turn of the synchronization switch to the synchroscope. The turbine is now synchronized to the 60Hz power grid.
What are the criteria for synchronization of a generator with the grid?
Voltages matchIn phaseGenerator should be spinning slightly faster than the synchronous speed of the gridThe second and third criteria are typically measured by a Synchroscope - see http://en.wikipedia.org/wiki/SynchroscopeFor more information on Power Generation, please visit http://www.powergeneration.edu.au

How do you write 'works' in French?
"works" as in "(road)works" is "travaux" (masc.) "works" as in "she works" (the verb) is "travaille".
