 +**Quadrature voltage transformer** - a name proposed by W.E. Sumpner for a circuit ensuring that the current flowing through a [[moving coil]] is in [[quadrature]] with the applied voltage. [(Sumpner>[[|William Edward Sumpner, Electrical measuring instrument, 1907, Patent US863008]])]

 +Quadrature voltage transformer can be used for a construction of a voltmeter[(Sumpner)]
 +//<sup>[[|United States Patent and Trademark Office]], Public Domain</sup>//
 +A [[capacitor]] of a suitable value connected in series with a [[moving coil]] will ensure that the current flowing through the coil is a derivative of the applied voltage (for sinusoidal signals it will be in [[quadrature]]). The circuit could be used for a construction of a [[voltmeter]] as described in the original patent.[(Sumpner)]
