ALTERNATING CURRENT DEVICES FOR OBTAINING A 90° PHASE SHIFT

摘要: An alternating current device for establishing adjustable currents having a 90° phase shift by which the in and quadrature components of an applied AC voltage may be measured. The includes variable mutual inductor resistor series with primary winding secondary thereof. are measured across these resistors. Precise calibration to compensate error errors due fluctuations frequency obviated providing capacitor parallel resistor. In addition, shunt connected reduce value inductance required induce given
