Installing a ThyssenKrupp 10K Drive system can actually help protect sensitive electronic equipment located in the building. Harmonic Distortion (HD) is the disruption of the waveform of alternating current that supplies most existing elevator drives. Excessive Harmonic Distortion can interfere with today’s sophisticated equipment. Some effects of excessive Harmonic Distortion:

• Overheating of Motors
• Lowering performance of emergency generator systems
• Increases objectionable noise
• Overheating of power factor improvement capacitors, sometimes to the point of explosion

The guidelines adopted by the Institute of Electrical and Electronic Engineers (IEEE) state that in the most restrictive cases, the Current Total Harmonic Distortion (THD) cannot exceed 5%. None of the standard drives now in place even approaches meeting that standard, except for TKE's.

Only the ThyssenKrupp 10K Drive system, which maintains substantially less than 5% THD, meets the IEEE standard.
