Equation 32. 10-Second Frequency Calculation
Example
Number of integral cycles: 501 cycles over 10 s
Total duration of the 501 cycles: 9.998 s
10-Second Frequency = 501/9.998 = 50.1100 Hz
Distortion
The voltage during a dip is often distorted. This distortion may be important for understanding the effect of
����
the dip on the system. The BE1-11g calculates distortion using Equation 33.
