Power Factor Meters
Power factor meters are intended for measurement of power factors in single or three phase networks, with balanced or unbalanced loads. The accuracy class is 2.5. They are mechanically very robust and can also be used on ships (they have CRS Approval). Power factor meters are available in two different sizes: the YQ x107 with 144x144 mm front frame and the YQ x207 with 96x96 mm front frame. They can also use different dials: the YQ 0x07 has a 90 degree dial and the YQ 2x07 has a 240 degree dial.
Dimensions of the YQ 0307 are 72x72 mm and it has 90 degree dial. The instrument operates on fast sampling method of input quantities (current and voltage) on all tree phases. Microprocessor calculates power factor (YQ) from the input data.
The YQ 0107 power factor meter has 144x144 mm front frame and 90 degree dial. It is the same as YQ 0207 (see photo), except it is bigger.
The YQ 0207 power factor meter has a 96x96 mm front frame and a 90 degree dial. It is designed for measuring power factors in three phase three-wire networks with balanced loads or in a single phase network.
Dimensions of the YQ 2307 are 72x72 mm and it has 240 degree dial. The instrument operates on fast sampling method of input quantities (current and voltage) on all tree phases.
The YQ 2107 power factor meter has a 144x144 mm front frame and a 240 degree dial. It is the same as the YQ 2207 (see photo), except it is larger.
The YQ 2207 power factor meter has a 96x96 mm front frame and a 240 degree dial. It is designed for measuring power factors in three phase three-wire networks with balanced loads or in a single phase network.
