Clamp harmonic power meter

UT243 is a digital three-phase clamp power/harmonic meter integrating digital ammeter, power measurement and harmonic measurement. It is composed of four channels of voltage, current, power and harmonic and a micro-chip microcomputer system.

The energy part (harmonic) in the power supply system other than the power frequency (50Hz) is generated by the distortion of the fundamental current when the sinusoidal voltage is applied to the nonlinear load (such as UPS power supply, switching power supply, converter, rectifier, inverter, etc.). If the harmonic wave is too large, it will cause high-frequency interference to the electrical equipment, which may cause damage or even burn down the equipment.

The U1243 instrument has the function of measuring three-phase total power, total harmonic distortion rate and single harmonic component. It is applicable to the measurement and maintenance of various regulated power equipment and power supply lines, as well as the evaluation of power quality, three-phase power measurement and harmonic analysis users.
