Frequency calculation for Oscillogram signals
For the program for viewing oscillogram in COMTRADE format, a function for calculating the frequency for analog signal from the oscillogram has been added.
Frequency
Signal frequency, calculation of signal frequency, simulation of electrical signals, frequency filter.
Simulation of Frequency Filter
In a previously published article, an option was presented to calculate the frequency of an electrical signal from a transition through zero. This article provides an example implementation of a frequency filter.
Calculation of the Electrical Signal Frequency
Some relay protection and automation functions require information about the frequency of the observed voltage or current. We will consider the option of calculating the frequency of the electric signal from the transition through zero.
