Software Functions
Password 1st level 2nd level Measurement scrolling System: Numeric code of max. 3 digits; 2 protection levels of the programming data Password "0", no protection Password from 1 to 255, all data are protected Active power (kW), reactive power (kVAr), power factor (cos ), current (A), average phase-phase voltage (V) total and partial active energy (kWh), total and partial reactive energy (kVArh) Partial energy meters: the counters of kWh and kVArh are automatically reset when the energy reaches the value (14999*CT). Example: the CT is a 100A/5A so the ratio is 20, consequently the maximum counted energy is 299980 kWh or kVArh. Active power (kW), reactive power (kVAr), power factor (cos ), current (A), phase-neutral voltage (V) For CT up to 5000 A 0.1 to 999.9 0 to 100% of the input electrical scale 1 to 64 On the display and on the variable being transmitted by the serial communication port.

PI/QI (installation power) One phase system:
PI = UI * II * cos QI = UI * II * sin
Pn /Qn (rated power of the instrument): One phase system:
Pn = Qn = Un * In * CT(ratio)
Three phase, 3-wire system:
PI = 3 * UI * II * cos QI = 3 * UI * II * sin
Three phase, 3-wire system:
Pn = Qn = 3 * Un * In * CT(ratio)
Three phase, 4-wire system:
PI = 3 * UI * II * cos QI = 3 * UI * II * sin
Three phase, 4-wire system:
Pn = Qn = 3 * Un * In * CT(ratio)
where: UI = the real star voltage of the electrical system being measured. I = the maximum phase current of the electrical system being measured. Cos = the average cos of the electrical system being measured.
where: Un = the rated input voltage of WM2-96. In = the rated input current of WM2-96. CT (ratio) = the value of the current transformer ratio.
In both examples the accuracy of the measurement is 1% f.s. when considering the changing of the measured voltage from 0.9 Un to 1 Un and the measured current from 0.1 In to 0.9 In with a cos of 0.85 (sin 0.52).
