Terminal voltage is the voltage between the output terminals of a generator.
The volatge regaulation be calculated by calculating the percentage difference between volatge at no load and voltage at full load
Full load amps for a three phase, 375KVA generator is 375 / (voltage in kV) / sqrt(3).
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
not you kan not start 22kw motor with 25kva generator (οχι)
self excited generator must be started without any external load attached ,an external load will continuously drain off the build up voltage and prevent the generator from reaching its proper operating voltage. also the presence of residual magnetism plays an important role And the field current resistance should be less than critic field circuit resistance
In a series generator, as load is added, output voltage increases.
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
The generator terminal voltage will increase.
Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.
A generator's terminal voltage can be raised by increasing the field current. This will result in an increased load on the generator, which will slow it down unless the governor kicks in to keep the generator at speed.

A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
When the generator is loaded, flux per pole is reduced due to armature reaction.
Generators are supposed to be started under no load conditions. The generator first starts and then runs to stabilize the voltage and then picks up the load. An automatic transfer switch makes sure that this procedure is followed. If it didn't then the voltage and current of the connected load would be at zero when the generator start. This ramping up condition is not good for equipment that expects a full voltage and current when starting and operating.

emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.
hi, when generator is running on no load,it is having its own load because of it produce some voltage drop,result electric energy is generated.
