The method consists in changing the value of R (the potentiometer) until the measured VR is equal to the measured VL. VR and VL will have the same “Value” but their “Phase” will be different. The voltage applied by the power transformer is not important and will not be part of the...
If there was active power factor correction you would get quite accurate results with just a couple of multimeters. I have a Voltech PM100 that makes the measurement a breeze. Dave recently did a teardown of a PM300 (3-Phase unit) that was interesting.I recently tried to measure the ...

Da im Drehstromsystem die drei Phasen ziemlich genau um 120 ° phasenverschoben und die Amplituden etwa gleichgross sind, kann aus der Spannungsmessung von einer Phase die der andern beiden Phasen errechnet werden. Die für die Leistungsmessung erforderliche Zuordnung von Strom und Spannung einer...
A method for measuring various measurable variables with a multimeter includes specifying one of a plurality of measurable variables to be determined through a position of a measurement range switch and/or through a selection between various input connections respectively assigned to the measurable variabl...
A method for measuring standard data sheet information for audio power amplifiers (APAs) is presented for several key parameters. These are: • THD+N versus output power • THD+N versus frequency • Gain and phase versus frequency • Integrated noise • Signal-to-noise ratio • ...
