Overview of Q96-FTZ Q72-FTZ Q96-FETC Q72-FETC Three phase power-factor meter

Three phase power factor meter is a portable electric current ratio meter structure. It is used for measuring the power factor of load in three-phase three wire balanced line with frequency of 45-65hz. For three-phase circuit cos Φ The dimension din43700 attached to the measuring converter complies with marine specifications and IEC standards. The principle and structure of converter type three-phase power factor meter are relatively simple. Using this measuring circuit is convenient for instrument serialization, standardization and miniaturization, and saves man hours and materials

Working priciple of Q96-FTZ Q72-FTZ Q96-FETC Q72-FETC Three phase power-factor meter

The three-phase power factor meter adopts the single-phase power factor meter of the electric system meter measuring mechanism. The principle is shown in the figure. Its movable part is composed of two moving coils perpendicular to each other. The moving coil 1 is connected in series with the resistor R and then connected with the power supply voltage u, and combined with the fixed coil (static coil) connected with the load current I, which is equivalent to a power meter, so that the movable part is subjected to a power uicos φ And deflection angle sine sin α Moment M1 proportional to the product of M1, M1 = k1uicos φ sin α 。 K1 is the coefficient, cos φ Is the load power factor. The moving coil 2 is connected in series with the inductor L (or capacitor C) and then connected with the power supply voltage u, and combined with the static coil, which is equivalent to a reactive power meter, so that the movable part is subjected to a corresponding reactive power uisin φ And deflection angle cosine cos α Moment M2 proportional to the product of M2, M2 = k2uisin φ; cos α 。 K2 is the coefficient.
