Harmonics Harmonics Up to 20th The 3286-20 provides the following 2 types of power factor measurement. If the waveform includes harmonic distortion, there will be a difference between the two measurement values, and the method must be selected accordingly. ●Power factor derived by phase discrimination (cos ø): 1ø Power Factor meter and 3ø Power Factor meter mode From the phase information for the fundamental frequency component, cos ø is calculated. This is suitable for assessing the quality of a power supply. ●Power factor (effective value power factor) derived from effective power ÷ apparent power: 1ø Power meter mode This is calculated from the power value including harmonic components (effective power ÷ apparent power). This is suitable for evaluating the performance of standalone load equipment and similar cases. * It is not possible to calculate the effective power factor of a three-phase line. 2 Packed into a Handheld Unit Helpful battery capacity check Whenever the unit is powered on, and while the record function is operating, the battery capacity can be checked to avoid battery exhaustion during measurement. ❏ Simple checking of three-phase lines ❏ For harmonic suppression 3ø Power Factor meter mode Load Source Power factor (cos ø) Harmonic measurement function Harmonics effective value/ total harmonic distortion Harmonics effective value/ harmonic percentage Phase angle (ø) Reactivity (sin ø) Harmonic coefficients Total harmonic distortion Ex.

Accurate measurement is not possible on a three-phase line if it is not balanced, for example when controlled by an inverter or thyristor. Cord length: approx 2m Since there is no integration function, it is not possible to measure total energy consumed (Wh). ❏ Check power supply fluctuations Max. and min. value displays Using the record function, it is possible to check the amplitude of fluctuations.
