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.
