resistive loads are best for testing ..they dont introduce phase changes

you may test ac devices almost the same as dc

inductive loads bring in lots of other factors that give confusing results

How do you define the synchronous generator capability limiters?

SYNCHRONOUS GENERATOR CAPABILITY LIMITTsynchronous generator capability limiters are as follows 1.MVA or armature current limit of generator: this depends on the cooling system of generator so that temperature rise in generator is limited to safe value.depending on cooling system effectiveness and temperature limit for the insulation used in generator, MVA limit is decided.2.MW limit: this is determined by the power output capacity of prime mover to which generator is connected.3.rotor angle limit: this is related to stability of generator which is synchronised to the grid.ideally this could be 90 degree, but in practice this is limited to70 degree so as to have better stability margin in transient and dynamic condition.the generator falls out of synchronism in trasient condition if rotor angle is close to 90 degree.4. rotor current limit: the field winding placed on rotor has got limited current carrying capacity, beyond which it may burn .so this limit is used.all these limitters make capability curve of g generator within which the generators operates safelyr. k.niranjanemail id: rkniranjan@yahoo.com


How can I find out which generator is better?

This site, http://www.electricgeneratorsdirect.com/stories/351-Serious-Electric-Generators-Worth-Bragging-About.html, contains some great electric power generators.


Will a 7500watt generator start a 2hp 15amp electric planer?

Use this formula W = A x V . Assuming that the saw is using 120 volts. 15 x 120 = 1800. Start up current on a motor will draw up to 300 % instantaneously so a 2000 watt generator might just do it. It would lug at the start but then catch up and run the saw. On motor from generator uses higher wattage is better.

Is ac better than dc for resistive heating?

no, heating is identical


Is a gas generator better than a gas turbine power generator?

A gas turbine power generator and a gas generator are quite similar, but they have their differences. For example, they are for things such as aircrafts which use them for mechanical energy. They are relatively safe to use, and it is better than a gas generator.


True or false Deductive reasoning is much better than inductive reasoning?

FALSE


Are propane powered generators better than any other type of generators?

I think propane generator are better than any other type of generator because Propane and natural gas can save you time, money and aggravation that's why i think propane generator is better than the other generator.


Which is better alpha testing or beta testing?

alpha. it's a more private testing.


How is random drug testing better then mandatory drug testing?

Random drug testing is better because it does not allow people the opportunity to prepare for the test.


What is a generic function?

Function generator can better be called as signal generator.It produces different types of signal like sine, saw tooth, triangular, pulse wave forms etc... can be produced.For testing any circuits which input must be a wave form like oscillator circuits function generator is used.


What is the goal of testing?

the goal of testing is to answer the unanswered questions of our universe and to have a better understanding of the concept we are testing.


Is it better to have a generator or electric supply for operating a snow cone stand?

It is better if you could use an electrical supply. The noise of the generator, interruption of power when the generator stops from lack of fuel and unstable voltages from loads being picked up and dropped are some of the drawbacks of using a generator.


Is an electric power generator safer than a natural gas powered generator?

You can purchase an electric power generator, but it won't do you much good if the electric goes out. A kerosene or deisel generator would be a better choice.
