Logging Function P

Logging Values

Voltage L1 or A, L2 or B, L3 or C: phase-phase or phase-neutral:

• Voltage (mean, min, and max values)

• THDV (mean, and max values)

• Flicker Pst, Plt

• Voltage events (dips, swells, interruptions)

Current L1 or A, L2 or B, L3 or C, and N:

• Current (mean, max values), THDI

Power:

• Active power P (mean, min, and max values)

• Absolute values active power |P| (mean, min, and max values)

• Apparent power S (mean, min, and max values)

• Power Factor PF, tangent

• Energy per averaging interval

Total Power:

• Total power P, |P|, S

• 3-wattmeter and 2-wattmeter method (Aron circuitry)

Application

Power logging:

• Long-term analysis of active, reactive, apparent power

• Long-term analysis of power factor, symmetry

Disturbance analysis:

• Examination of voltage dips and swells, flicker measurement

Network optimization:

• Load measurements, acceptance of new loads

• Efficiency of compensation systems
