Telephone harmonic factor of generators

[pentatek]

Hi There

Could any one assist in replying to the following:
According to IEC 60034-1 the THF of generator must be recorded using line-to-line voltages. The measured quantites during a test were however taken from phase-to-neutral values. Can the formula still apply? Unfortunately the phase angle of the harmonics were not recorded. This way it could have been minipulated to give the correct line-to-line values. Any suggestion on the topic will be appreciated

Thanks

Suggestion: Comply with
Telephone influence factor (TIF): NEMA MG-1-22.43 standards
Telephone harmonic factor (THF): IEC 60034-1, B.9.2 requirements
Line-to-Line may have different harmonic content than Line-to-Neutral. It would be prudent to consider the worst case.
