How to check the Power World Alternator working condition ?
1. Too low voltage of the genset under a load
A. Check if the rotary speed of the genset is normal.
B. Check if the UFRO set of AVR is correct.
C. As per the test of excitation separation, check AVR.
D. Damage of rotary diode.
2.Too low voltage at free running of the genset
A. Check if the rotary speed of the genset is too low.
B. Check if l -- 2 connection of AVR or outside connected manual micro adjustment is perfect.
3.Too High of Output Voltage
A. Check if the rotary speed of the genset is too high.
B. Check if the load of the genset is of capacitive load (leading power factor).
4. Unstable Output of Voltage of the Genset
A. Check if the rotary speed is stable.
B. Check if the setup of stability is correct.
5. During running of the genset, no voltage outputs
A. Check the connection ofK1 -- K2 from AVR is correct and reliable.
B. Check the rotary speed of the diesel genset.
C. Check the residual magnetism voltage, charge magnetism if necessary.
D. As per the test of excitation separation, check alternator and AVR.
