Three-phase voltmeters are used for measuring the voltages between phases, or phase-phase and phase-neutral in a line. They incorporate a switch in order to select the wires between which the measurement is desired. Their frequency range is 25 to 100 Hz. They indicate the rms value of the voltage, even with high harmonics, with a minor influence on the accuracy.
