What are the PQ IssuesFacing the Water Industries?

1) Power Factor

Motors typically cause low power factor

2) Harmonics

VFDs cause harmonics

3) Motor life when controlled by VFDs

Motors can be susceptible to PWM voltage

produced by VFDs

1.) What are the benefits ofImproving Power Factor?

High Power Factor saves energy

High Power factor can reduce energy

costs (eliminate PF penalties)

High Power Factor reduces load (KVA)on existing transformers more

capacity available for new loads

2.) What are the benefits ofReducing Harmonics?

Improve facility voltage quality

Reduce TRMS current and KVAsupplied by transformer

Stop C/B tripping and fuse blowing

Protect power factor capacitors

3.) What are the benefits of convertingPWM to Sine Wave Voltage?

You can use any length of motor cable.

Motors run cooler when supplied with

sine wave voltage.

Motors last longer when supplied withsine wave voltage.
