17e harmonic from a 6000hp synchronous motor
17e harmonic from a 6000hp synchronous motor
(OP)
We have a 18 poles, 3 phases and 153 slots synchronous motor, generating 1.6% THD with 1.3% corresponding to 17th (seventeenth) harmonic on its 4160 volts supply and 2.1% harmonic current of the 420.6 amp. 60 Hz supply.
Could you please reply with your comments ?
PS : This harmonic does not come from the supply.

RE: 17e harmonic from a 6000hp synchronous motor
IEEE Std 519 §10-11 seem to indicate that the cited values are below action levels for distortion limits. They are likely of no significant consequence.
Have you observed any suspect operation of related systems that might lead to concern?
