5.7 IEEE 519 Conformance
The eighteen-pulse nine cell GenIV drive was factory tested at SIEMENS and was found to
meet IEEE 519 for the most stringent TDD limits. The pre-existing voltage distortion was less
than 2% and the primary current contained a K-factor of less than 2.

Note
Fifteen and twenty-four cell drives further reduce the drive input current harmonics by
increasing the input pulses to 30 and 48, respectively.
