Flashing field on voltage regulator
Did you know?
WebField voltage, supplied to the exciter field via the voltage regulator, will always be greater in an overload con dition than in normal operating conditions. When only a small difference or no difference between the auxiliary voltage (pin #2) and the exciter field voltage (pin #1) is found, it could be an indication of a generator over load. WebPerform a test called “full fielding” the alternator. With the alternator field isolated from the regulator, connect a jumper from the B+ alternator output to the field terminal. This will provide full bus voltage directly to the …
WebOnce the current drops to an acceptable level, the voltage regulator takes over, and controls maximum charging voltage. Either the current regulator or the voltage regulator is in control, depending on current flow, not both at the same time. Now, where does the generator get its field current in the first place? It must be "polarized." WebApr 5, 2024 · The automatic voltage regulator (AVR), commonly known simply as voltage regulator, executes all control functions of the system, including the following: Operating breakers Sending firing pulses to …
WebApr 5, 2024 · The field flashing circuit is used in the start-up process, when the magnetic flux in the generator is too low. The field of the synchronous machine is temporarily … WebRemove exciter field leads F+ and F- from the voltage regulator. CAUTION: Failure to remove the field leads from the regulator during flashing procedures may destroy the regulator. 2. Measure the exciter field resistance from the F+ to the F- lead. You should be able to read some resistance as you are measuring a continuous winding.
WebThe regulator provides voltage to the exciter field resulting in a build-up of generator terminal voltage. This system of using residual magnetism eliminates the need for a special field flashing circuit in the regulator.After the generator has established the initial residual voltage, the regulator provides a controlled DC
