  • Typical applications range from 480v through 35 KV
  • Harmonics can cause the following:
    • Abnormal Heating of Equipment
    • Transformer overheating. Transformer failure or life reduction.
    • Excessive capacitor fuse failures. Capacitor problems.
    • Equipment operation problems or damage.
    • Interference to communications.
    • Excessive voltage distortion. Possible relay and metering problems.
  • Harmonic filters can typically be designed to reduce harmonics by detuning the system to reduce harmonic amplification.
  • Properly sized harmonic filters will also usually change the power factor to somewhere in the range of .95 to .99 as well for substantial power bill savings.
  • We manufacture our own iron core or air core reactors custom tuned to the customer’s specific needs.
