Aircraft voltage regulator troubleshooting.

These solid state regulators along with glass cockpit warning systems are providing faster but not necessarily better information to the aircraft s pilot and mechanic. And re approximate bus voltage at alt f1. A drop of more than 0 5. If it does the generator is o k.

2 y e s approximate bus volts at voltage regulator field out. Zeftronics designs and builds protective sensors alternators regulators general controllers for safer more efficient aircrafts. If you don t have 12 volts at all of these points when the master switch is turned on find out why and fix it. Troubleshooting flow chart for externally regulated alternators record aircraft bus voltage v start approximate bus voltage at alt b.

If you get a high voltage reading like 14 8v or greater than the alternator is ok and the problem is either the regulator or the wiring to from the regulator. Verify both the input and output voltage of the regulator. By using the technique of decoupling control the mathematical model of the three phase power converter is developed in the dq rotating reference frame and it is linearized around the operating point. The input voltage should be approximately the same as the bus voltage.

Voltage regulator troubleshooting tips. The input voltage should be approximately the same as the bus voltage. Loose connectors can be the toughest problems to find so be sure to tug on each one to make sure it is secure. Check and record voltage of aircraft bus check to be certain ground strap is properly connected at alternator f2 check for bus voltage at alternator f1 check for bus voltage at regulator fld replace wire or connectors from regulator fld to alternator f1 replace wire or connection replace wire or connection to bus replace wire or connectors from regulator enable to.

Y e s approximate bus volts at. If you get a low voltage reading like around 12v then the alternator is the issue. If battery voltage is not present at the field terminal of the alternator with the al ternator control switch turned on the volt age regulator may be suspect. A drop of more than 0 5 volt would indicate an issue upstream of the regulator.

Aircraft voltage regulator troubleshooting this paper proposes a combined power quality optimal control of the three phase grid connected power converter. Warranty management registration. Btw make sure you only run the engine for about a minute if the voltage reading is high otherwise you might fry something. No check f2 ground strap installed.

No voltage should be present at the aux sta terminal. Record aircraft bus voltage. The voltage on the armature post should follow the throttle. Battery voltage should be present at both the alternator battery terminal and field ter minal.

Make sure that when the master switch is on that you have battery voltage of at least 12 or 24 volts on the regulator battery terminal. Verify both the input and output voltage of the regulator. Also check the led indicator. If so the trouble is most likely the voltage regulator.

If the drop between the input and the output of the regulator is beyond. Services support.
