Mayor of a mathematical city promised that electrical energy will be free for their future citizen, because they will consume no energy for electrical power generation!!
In static excitation system (with brush)of large power plant generators
excitation voltage is supplied by 3-ph excitation transformer with typical vector group YD5 or DY5.
An industrial power system includes one gas turbine generator (6KV, 12 MW), a step up transformer (6/20 KV, Dyn11, 20 MVA) and relevant distribution system.
Hi,
i am working in a motion capture project one of its parts is a sensor
i need a formula of the voltage generated in the coil due to moving in electromagnetic Field from an inducer
When a generator is operating in parallel with another same size generator, what will be the effect of changing governor set points and field currents?
In power generation plant with several ungrounded generators and grounding only one generator, how can unearthed generator affecte from network earth faults?
Energy savings with lower frequency
We are consuming 50,000 Wh per day with 50 Hz 435 V , But when we reduce the frequency to 49 Hz , conumption will reduce to 2000 Wh
We have a generator feeding into an incomer, along a distance of about 15m. during ac pressure tests it was fine, all the phases and neutral were tied down to earth, and each one was tested individually.
It is well known that, if an Alternator is connected with Grid its (alternator) voltage can not be change and it follows the grid voltage but i've seen that when its excitation changes its voltage also changes, why?
