Power factor meters

The power factor meter is a magnetoelectric device with an electronic converter, housed in a standard housing. Meters of the PFQ type are designed to measure the phase angle between an alternating voltage and the corresponding alternating current, converting the signal into proportional direct current. This device cannot be used on a network supplying a non-linear load.
