Power Meters
Power meters are electronic meters intended for measuring active or reactive power in single or three phase networks, with balanced or unbalanced loads. The accuracy class is 1.5, but on request we are also able to produce class 1 meters. They are mechanically very robust and can also be used on ships (they have CRS Approval). The scale value depends on primary values of current and voltage. The power meters are in two different sizes: EQ x107 with 144x144 mm front frame and EQ x207 with 96x96 mm front frame. They can use also different dials: the EQ 0x07 has a 90 degree dial and the EQ 2x07 has a 240 degree dial.
Dimensions of the EQ 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 three phases.
The EQ 0107 power meter has a 144x144 mm front frame and a 90 degree dial. It is the same as the EQ 0207 (see photo), except it is larger.
The EQ 0207 power meter has a 96x96 mm front frame and a 90 degree dial. The instrument operates on the Time Division Multiplication (TDM) method.
Dimensions of the EQ 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 three phases.
Power meter EQ 2107 has 144x144 mm front frame and 240 degree dial. It is the same as EQ 2207 (on photo), except it is bigger.
The EQ 2207 power meter has a 96x96 mm front frame and a 240 degree dial. The instrument operates on the Time Division Multiplication (TDM) method.
