George E asked Where would the electric current go if everyone on the power grid were to shut the master power switch off?

In other words, an isolated location has a large power generating plant that does not feed into a larger power grid but generates power for 1 million homes and businesses, where would the current go if all one million customers were to throw the master power on/off switch to off at exactly 1:00 PM on July 15, 2008? Thanks

And got the following answer:

The current would not go anywhere. It would just stop. The load - the customers - dictate the current and the power. A single generation station has control of frequency and voltage. Not much else. If you were to coordinate one million customers to simultaneously turn off power, equivalent to the power station opening its output breaker while at full load, it would then dependant on the electrical protection relay scheme of the power plant. The frequency and voltage output of the power plant would rise a lot. Some plants have trips associated with excessive frequency - somewhere between 62 and 64 Hz - and some have trips associated with excessive line voltage or excessive volts/hertz. Some of these trips have a time delay with them to allow for the automatic controls to lower the voltage and frequency before tripping the generator's output breaker. Dependant on the type of power plant many other things will happen. For a gas turbine plant the gas valve on the GT will throttle back really quickly. That's about it. For a steam plant the throttle valve for the steam turbine will throttle back really quickly, but back up steam pressure and probably lift a steam safety before the fuel can be reduced to lower the heat to the boiler. A hydro plant will just quickly reduce the flow of water to its turbines. Might shutdown the power plant, might not. To the Mormon Engineer - Which energy source that produces electricity for our consumption in the US comes from the middle east. Very frickin little you moron. Quit perpetuating your republicunt propaganda

The current protection relay operate exceptionally well with different applications that happen to be particular to power distribution and protection. The relays come with wide adjustment ranges using a scale that is easy to read either in three or four digits in accordance with the model. These current protection relay support in escalating the flexibility on the applications, lower the overall energy and upkeep fees. You will find relays that are used for basic purposes which come in reputable styles with rapid replacement possibilities. And there are actually models which might be used for industrial applications and heavier duty applications that operate on substantial loads. These merchandise are made to meet the lifetime industrial control requires on the applications.
Their most up-to-date items would be the Time counter, Timer Delay, current protection relay, Swift Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and several other individuals. The web page presents a detailed description of every single model in various categories of current protection relay couplings and sensors. These merchandise are very useful for high-risk applications. The current protection relay are also offered with attributes like multiple timing ranges and functions. The firm is presently in search of agents and dealers who can promote and sell their factory produced merchandise. They are generally on a lookout for establishing new and more reliable products depending on the demands and requirements from the industry.
