What are the signs of a faulty AVR in a generator?
1 - Unstable generator engine speed.
2 - Current overload.
3 - Power surge.
4 - Short circuit.
5 - Age.
What causes an AVR to fail?
It was concluded that the cause of AVR damage was due to the generator driving motor which experienced a decrease in performance so that when subjected to electric load the engine rotation experienced instability which caused voltage fluctuations where this caused the AVR to work abnormally resulting in AVR damage.

Description:
Automatic Voltage Regulator AVRSpecification:
Sensing input:
- Voltage: 277 VAC ± 10% for 1-phase,
415 VAC line-to-line ± 10% for 3-phase,
2-line sensing. The AVR senses the true
average of the line-to-line waveform. Use
the resistor (SMD) network for trouble-free
Sensing and control of sensed voltage/regulation.
Input power:
- Voltage: 277 VAC rms ± 10%
- Frequency: 50/60 Hz
Output power:
-Voltage: 95 VDC for 240 VAC Input
-Current:
4 A DC
6 A for 30 sec. (when allowed by the field resistance)
Operating temperature: -20ºC to +70ºC
Storage temperature: -40ºC to +80ºC
Voltage setting: min ± 10% of rated voltage.
Stability setting: can be adjusted to obtain
a correct transient response in a steady state.
Under frequency roll-off setting: available
Below 46 Hz for 50 Hz and below 56 Hz for 60 Hz.
Voltage build-up: 2 Volts (L-N)
Voltage regulation: ± 1% at the AVR
terminals with a THC <5%.
Thermal drift: ± 1% for 30ºC change in temperature.
Response time: less than 50 ms.
Closed loop response: typically 0.5 sec to recover 98% of the defined voltage for a field forcing ratio of 1:2.
Sensing loss protection: the voltage
should disappear when the sensing circuit is open.
Overexcitation protection: 10 VDC to 85 VDC.
Set point: 60 VDC
Protection fuse: 4 A, 240 VAC.
Potentiometer sealing: except for the
V-trim potentiometer, all potentiometers are sealed.
Frequency roll-off indicator: LED provided (UF).
Sensing loss indicator: LED provided (SL).
Overexcitation indicator: LED provided (OE).
Protection on the devices: suitable R-C
snubber to be provided for the device used
to protect against voltage surges.
Potting/Encapsulation details: the
components on the AVR should be
completely encapsulated with suitable PU
resin compound to absorb transients/
vibrations during operation.
Alternator excitation details: (typical)
-Full load:
Excitation voltage: 40 to 50 V
Excitation current: 2.5 to 4.0 A
