Watt- and Var- meters, Type WQ

WQ type wattmeters and varmeters are designed to measure power in single-phase and three-phase networks with both symmetric and asymmetric load distribution over phases. The WQ type watt and varmeters include: an electronic measuring unit that converts power into direct current and an indicator - a direct current ammeter with a magnetoelectric measurement system.
