Tektronix MSO58 Printable Help

Power Quality measurement algorithm. The Power Quality measurement calculates the Frequency and RMS values of the
voltage and current, Crest Factors of the voltage and current, True Power (TrPwr), Reactive Power (RePwr), Apparent Power
(ApPwr), Power Factor (PF), and Phase Angle (θ) of the AC signal.
■
RMS Voltage: The application calculates the RMS voltage using the following equation:
Where:
V
RMS
is the RMS voltage in Volts.
N is the number of samples.
n is the data point.
v(n) is the absolute value of the voltage at the particular data point.
NOTE. The voltage RMS is for all the time domain cycles in the acquisition.
■
RMS Current: The application calculates the RMS current using the following equation:
Where:
I
RMs
is the RMS current in Amps.
N is the number of samples.
n is the data point.
i(n) is the absolute value of the current at the particular data point.
■
Apparent Power (ApPwr): It is the product of the RMS voltage and current (mathematically, the absolute value of the
vector sum of the true and reactive power), measured in Volt-Amperes or VA. The application calculates the Apparent
Power (ApPwr) using the following equation:
Where:
ApPwr is the Apparent Power, Volt-Amperes (VA).
V
RMS
is the root mean square of the voltage.
I
RMS
is the root mean square of the current.
