Sensitive Directional Power; Synchrocheck - GE L90 Instruction Manual

CHAPTER 6: ACTUAL VALUES
The harmonics are a percentage of the fundamental signal obtained as a ratio of harmonic amplitude to fundamental
amplitude multiplied by 100%. The total harmonic distortion (THD) is the ratio of the total harmonic content to the
fundamental:
Voltage harmonics are calculated only for Wye connected phase VTs. Ensure that the
