Case Studies

A coastal utility procured their first metal enclosed capacitor bank from Controllix Corporation. The customer was accustomed to using open rack style capacitor banks, but a fully welded metal enclosure protects equipment during weather related events such as hurricanes. The metal enclosed design is also ideal for keeping wildlife away [...]

A mid-west utility approached Controllix with a request to replace their existing outdoor metal enclosed 34.5kV, 1200A fixed breaker used for the daily switching of a remotely located Controllix 10.8MVAR capacitor bank. A capacitor switch with a pre-insertion resistor to limit the inrush current was chosen in place of the [...]

A midwest foundry commissioned Controllix for multiple metal enclosed harmonic filter equipment. Each project involved a single stage harmonic Filter with 5th and 11th harmonic tuning frequencies. The 11th harmonic filter also included a high pass resistor.  The successful installation of the harmonic filters reduced the foundry’s energy costs and filtered harmful harmonics [...]

A large midwestern utility sent an October quote request to Controllix requiring a total of 76 large (6000 and 9000kvar) metal enclosed capacitor banks at 13.8kv. There were 11 equipment designs to accommodate various substation limitations. All 76 units needed to be on site at 36 different substations by the [...]

  A major New England utility installs capacitor banks at various substations to provide voltage support during normal and contingency operating conditions. In certain conditions at the particular substation, the voltage levels were unacceptable and it was determined that two (2) 46kV, 3600KVAR capacitor banks were required. Due to local permitting [...]
