Gilbert Electrical Systems has been analyzing, engineering, designing and manufacturing harmonic filter assemblies since 1983. The need to provide solutions to power factor and harmonic problems has been long recognized. Utilities and industrials have had to address harmonics and the associated problems they create for many years. Harmonics create many problems on customer systems:

  • Abnormal equipment heating
  • Premature transformer failure
  • Reduced equipment life
  • Excessive capacitor fuse failures
  • Capacitor problems
  • Communications interference
  • Excessive voltage
  • Transformer overheating
  • Potential relay and metering problems
  • General equipment problems or damage

GES has a core competency in this area. Our engineering and study group possesses the technical expertise to analyze a customer’s needs and provide a well engineered package of harmonic filter/capacitor banks from 480V to 35 kV that satisfies their system objectives.
