    Odd voltage reading from digital volt meter

    Sorry, but I don't have a diagram or photo of this setup. I designed a circuit that interfaces into the alternator to collapse the magnetic field of the system. It seems to have worked, just odd output results. I used a short circuit as a load to provide a high counter torque on the alternator...

    Odd voltage reading from digital volt meter

    The source per phase winding had a resistance of 0.7ohm. I tried to get a current reading with a clamp meter and it was showing zero amps. I thought the value of voltage across the load was current x resistance. I tried to measure the load voltage many times with different multimeters and they...

    Odd voltage reading from digital volt meter

    The resistance of the load is less than 0.0003 ohm. The voltage across the load is in excess of 100 volts. There is regulation for the field, it is supplied by a separate DC source.

    Odd voltage reading from digital volt meter

    I tested all the meters and the DC and AC voltage measurements are correct with the appropriate supply. The load I am using is basically a short circuit, It drops 99.95% of the power across the load. The frequency remains stable at 240Hz with no fluctuation.

    Odd voltage reading from digital volt meter

    I had the volt meter set to AC volts.

    Odd voltage reading from digital volt meter

    I have a three phase alternator and I used a digital voltage meter across the output terminal and the reading went from OL to 4000 volts to 3000 volts and quickly decreased to zero volts, then went through the range again starting from OL. It continued to do this, I thought the meter could have...

    Series lc circuit and clamp-on ammeter

    The capacitance in the circuit is 500uF, the inductance of the circuit including the wires is 810.56uH and the resonant frequency is 250Hz. I measured the inductance of the wire to be 13.5uH with a MTP MS5300 inductance meter. The clamp meter I am using is good for frequency from 50Hz to 500Hz...

    Series lc circuit and clamp-on ammeter

    When calculating the capacitance for the circuit I did include the inductance of the wire. The resonate frequency is less than a kilohertz. I measured the circuit inductance with and inductance meter and the value dropped below the inductance of a single wire. I just wanted to be sure because...

    Series lc circuit and clamp-on ammeter

    In a series LC resonant circuit the capacitor acts to cancel out the inductance of the the circuit. With no inductance in the circuit the magnetic field will collapse. So my question is, with this collapse of the magnetic field will it be be harder to measure the current in the circuit with a...

    Calculation for power factor

    I'm trying to calculate the power factor of a three phase synchronous generator torque angle = arctan^-1 (impedance) (sin torque angle/ current x voltage) 90 - torque angle - sin = XYZ power factor is cosine XYZ Is this the correct calculation to use?

    Counter torque, voltage and current

    is counter torque affected by voltage and current phase shift?

    Counter torque, voltage and current

    When an ac generator produces high current the counter torque increases, but if voltage increases would the counter torque decrease? Is counter torque related to counter EMF?

    Can Magnetic Fields Couple and Affect Each Other?

    Can a weak alternating magnetic field from one coil have an effect on another coil that has a stronger alternating magnetic field? I ask this because I want to know if magnetic fields follow the same principal as coupling two different voltages together.

    Torque angle and power factor of generator

    I need someone to clarify for me how an increase in torque angle in an ac generator increases the power factor. Does the torque from the rotor force the current in phase with the voltage on the stator.

    Question on power plant generators

    Sorry but I'm more interested in the electrical side of it and less on the actual mechanical side of the operation. I have been trying to find info in the internet but so far not successful.
