METHOD FOR DETERMINING A RELATIONSHIP BETWEEN TWO SINUSOIDALLY PERIODICALLY VARYING VARIABLES AND DIAGNOSIS DEVICE

In order to determine a phase ratio between two predominantly sinusoidally varying variables, respective measurement values for the two variables are expanded into complex numbers, then a ratio variable c[k] is calculated directly from these complex numbers, the average c of all ratio variables is d...

Zusammenfassung:In order to determine a phase ratio between two predominantly sinusoidally varying variables, respective measurement values for the two variables are expanded into complex numbers, then a ratio variable c[k] is calculated directly from these complex numbers, the average c of all ratio variables is determined, and then a statement about the ratio between the two variables can be made on the basis of this average. The invention is particularly suitable when the loss factor for a medium or high-voltage cable is to be determined.
