Resonance Harmonic Filter
The Omniverter REHF filters are used to correct harmonics or resonances at higher frequencies, typically higher than 11th Harmonic.
Conventional LC circuits can shift a potential network resonance to another frequency but cannot completely eliminate the potential resonance from the electrical system. The REHF includes a highpass resistor to eliminates resonance from the electrical system.
REHF units are designed specifically for customer site conditions. They are available at Low Voltage up to 600V, MV or HV using transformer coupling.
Electrical Resonance
Electrical resonance can occur in electrical circuits at a particular frequency (resonant frequency). Resonance can result in very high levels of voltage or current and create catastrophic equipment failure.
Potential consequences of electrical resonance - equipment failure:
- Overvoltage
- Overheating
- Fire
- Equipment Damage
- Eliminate resonance
- Correction of voltage transients due to switching of utility capacitor banks at MV or HV.
- Can correct harmonics > 11th Harmonic
- Eliminates voltage notching from DC drives
- Voltage controlled, no CT’s needed
- Utilities
- Industrial processes
- Semiconductor & Pharma facilities
- Automation and robotic applications
- Hospitals and Automation
