HGL HarmonicGuard Low Capacitance

Our HarmonicGuard Low Capacitance filter (HGL) adds to our line of options for passive filters. The HGL was designed to be compatible with 5%THD performance.

The introduction of the HGL addresses concerns of excess capacitance in generators. Excess capacitance can cause problems such as:

  • Causing leading Power Factor
  • Creating over-excitation in a generator
  • Controling both power factor and harmonics together

The Low Capacitance filter reduces the amount of reactive power and enables lower power, lower cost generators to be used.
