RPV311-TM-EN-6
¹ Is not calculated for circuits of 1 element without 3-phase synthesis.
² Is not calculated for neutral circuits.
The fundamental frequency of the input signal must be within a range of ± 6 Hz of the nominal frequency of
the electrical system.
Power Measurement:
Power measurement is computed based on the values of a voltage circuit and a current circuit. The following
values are computed once per cycle:
Voltage and current measurement
S
Combined apparent power
S
1
Fundamental apparent power
P
1
Phasors ¹
Q
1
Phasors (neutral) ¹
Reactive power has a positive sign for circuits with inductive characteristics and a negative sign for circuits
with capacitive characteristics.
DC Transducers Measurement:
The RMS value of the DC channels (transducers) is calculated once per cycle.
High-speed Voltage Measurement:
There is an 8-bit opto-isolated analog-to-digital converter, independent for each channel. The acquisition is
performed with 5 MHz sampling frequency (high-speed channels), that means one acquisition each 200 ns.
