a diode in the exciter has blown or leaking current back and forth, test diodes with a multi meter continuity test.

It sounds like the field excitation voltage has been lost. Check that the field potentiometer has not been turned down to the off position. Check at the F1 and F2 outputs of the voltage regulator for any DC voltage.

How variable speed generator works and its specification?
First you have to understand how a generator works. Basically the excitation voltage is what varies according to generator output. Usually on a power source that has a inconsistant rpm, the excitation voltage will vary similar to a govenor in order to hold the generator output constant.
How do you troubleshoot generator that fails to supply ac voltage?
You first use the schematic diagram in the equipment service manual to understand the flow of the power and signals in the generator. The first thing to check is all of the power supply voltages. If one is missing, the generator can fail in such a way as to produce no output. Then you can use an oscilloscope to trace the problem backwards, from the output connector of the generator to to the source of the signal generation.
Why a given generator frequency is dictated by the size of the magnetic flux?
A generator's frequency is dictated by the power system frequency, and the number of poles in the generator. For 60 Hz power and a generator designed with two poles, the generator must turn at 3600RMPs (60 Hz * 60 seconds / minute). The magnetic flux is what induces the current in on the output winding. Spinning a synchronous generator faster or slower is not done to control the magnetic flux. The field winding voltage is varied to control this, and in turn control the output of the generator.
In an AC power supply system what component connects the 115 200 VAC main generator output to the main power buses?
GLC
How can an ac generator be converted to DC generator?
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
What is the output of a bicycle generator?
The output of a bicycle generator is electricity, which is generated by pedaling the bicycle to power a generator that converts mechanical energy into electrical energy.
How much power does a 5.5 kw generator produce?
A 5.5 kW generator produces 5,500 watts of power. This is the maximum power output that the generator is capable of producing under optimal conditions.
What is DC generator?
because DC generator generates generally generate DC power but as it has slip rings which convert it into ac output power
What is the efficiency of a dc generator that requires 200 watts of energy to supply 160 watts of output power?
The efficiency of a DC generator can be calculated using the formula: Efficiency (%) = (Output Power / Input Power) × 100. In this case, the input power is 200 watts and the output power is 160 watts. Thus, the efficiency is (160 W / 200 W) × 100 = 80%. This means the generator operates at 80% efficiency.
How many watts is a wacker G3.7 generator?
The Wacker G3.7 generator typically has a rated power output of around 3.7 kilowatts, which is equivalent to 3700 watts.
Advantages and disadvatages of a self excited induction generator?
The main disadvantage should be obvious - when the output voltage of the generator is used to provide field current to the generator....what happens if the output voltage sags? If the output voltage becomes depressed, the output power of the generator is compromised (becomes less and less), this in turn can cause the output to become more depressed, leading to an incrementally decreasing output capability. The main advantage is cost savings.
The relationship of the strengths of the two fields in a generator determines the amount of what?
The relationship of the strengths of the two fields in a generator determines the amount of electrical output or power generated by the generator. When the magnetic fields are strong and properly aligned, it results in a higher voltage output and more efficient power generation.
How much power can a bicycle generator produce and what factors influence its output?
A bicycle generator can typically produce around 100-300 watts of power, depending on the speed at which the bike is pedaled. Factors that influence its output include the efficiency of the generator, the resistance in the system, and the speed at which the bike is pedaled.
What power generator will you require to run a 2.5hp 50 liter compressor?
To run a 2.5hp 50 liter compressor, you will need a power generator with a minimum continuous power output of 1.85 kW. It is recommended to choose a generator that can handle a slightly higher power output to account for any fluctuations in power draw when the compressor starts up.
How variable speed generator works and its specification?
First you have to understand how a generator works. Basically the excitation voltage is what varies according to generator output. Usually on a power source that has a inconsistant rpm, the excitation voltage will vary similar to a govenor in order to hold the generator output constant.
What does increasing the number of coils on a generator do?
Increasing the number of coils on a generator can increase its voltage output. More coils mean more wire loops, which can generate a stronger magnetic field and induce a higher voltage. This can be useful in increasing the power output of the generator.
Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
