WC / FC analog wattmeters, varmeters, power factor meters (cos φ) and frequency meters
Country: Spain · Model: WC / FC
The analog panel wattmeters, varmeters, power factor meters and frequency meters of the WC and FC series give a clear pointer indication of power, power factor and frequency. They are installed in generator, synchronizing and marine panels, as well as in substations and industrial switchgear. The housings range in size from 48×48 to 144×144 mm.

Description
Electronic wattmeters with a built-in transducer show active power steadily in single-phase and three-phase, balanced and unbalanced networks, and induction ones are designed for long-term operation, as are varmeters for reactive power. WC series models, for example WC3V and WC5VrE, have different scales. Power factor meters measure the power factor with a CAP 0.5–1–0.5 IND (90°) or 240° scale. The reed frequency meters FC5V, FC4V, FC3V and FC2V (48×48, 72×72, 96×96 and 144×144 mm) have 7–21 reeds, ranges from 48.5–51.5 to 45–55 Hz (55–65 Hz for 60 Hz), a dual-scale 50/60 Hz version, an accuracy of 0.5 % and a consumption of 1.2–2.2 VA, and FC3V has a DNV certificate. The pointer-type FC5A–FC2A with a 90° scale have an accuracy of 0.5 % and a consumption of 10 mA. For comparing frequencies during synchronization there are the dual FC3VI, FC2VI, FC3AII and the differential FC3AD.
How to choose
The type of instrument is determined by the quantity. Active power is measured by wattmeters, reactive power by varmeters, and phase shift by power factor meters. For frequency take a reed FC_V if a clear scale is needed, or a pointer FC_A. For comparing two networks during synchronization, dual or differential frequency meters are required. Choose the cutout size, 48×48, 72×72, 96×96 or 144×144 mm, and the voltage to suit the panel.
