Harmonics are distorted electrical waveforms that introduce inefficiencies into your electrical system. They produce wasteful heat and can cause plant issues and fees from your local power company.
Harmonic frequencies flow into the electrical system as a result of nonlinear electronic switching devices, such as variable frequency drives (VFDs), computer power supplies and energy-efficient lighting. Similarly, companies with heavy motor, VFD and lighting loads need to be aware of the problems that harmonics can cause.
These problems include:
- Increased electrical usage
- Increased wear and tear on motors/equipment
- Higher maintenance costs
- Power quality problems upstream and downstream
- Utility penalties for introducing problems to the power grid
