Summary: Controllix Corporation transitioned a coastal utility from using open rack style capacitor banks to their advanced metal-enclosed capacitor banks. This change notably improve...
Existing Equipment Retrofit
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 [...]
Transforming a New England Substation with Controllix’s Metal-Enclosed Capacitor Banks
Summary: A major New England utility facing voltage instability and stringent local permitting requirements found a reliable, space-efficient solution with Controllix Corporation's metal-enclosed capacitor banks. The design met all operational needs and local guidelines while requiring significantly less space than a conventional open-rack design. Enhanced with features like a safety [...]
Harmonics in Electric Power Systems: Effects and Prevention
Modern electrical installations supply power to a wide variety of non-linear loads, where the current drawn does not have a linear relationship with the voltage supplied. In other words, even if the supply voltage signal is a perfect sinewave when measured with an oscilloscope, the resulting current may have a [...]
North America will attribute towards the Passive Harmonic Filter Market Growth By 2025
Harmonics in an electrical system/equipment occur due to fluctuations in the current or voltage. The propagation of harmonic frequencies is one of the most important cause of power quality problem in the electrical systems. Harmonic causes torque fluctuations, misfiring in variable speed drives and heating in the system. Thus, in [...]
The high price of poor power quality
Power quality and harmonics have been a developing and growing concern as buildings have become more reliant on technology, the ever-increasing utilisation of digital control systems, and the drive towards more efficiency. In recent years, harmonics from buildings have caused issues to supply networks, and authorities now require owners of [...]
Rising Adoption of Passive Harmonic Filter in North America will Boost The Market Growth
Harmonics in an electrical system/equipment occur due to fluctuations in the current or voltage. The propagation of harmonic frequencies is one of the most important cause of power quality problem in the electrical systems. Harmonic causes torque fluctuations, misfiring in variable speed drives and heating in the system. Thus, in [...]
Low Voltage Harmonic Filtering Equipment – Automatic
Harmonic problems are becoming prevalent because more equipment producing harmonics is being applied to power systems. The need for continuous control of certain industrial processes has led to an increase in electronic equipment and motor drives, which produce high harmonics. Poor voltage waveforms, due to harmonics or transients can lead [...]
Low Voltage Capacitor Banks – Fixed
Individual power factor correction is achieved by connecting capacitors directly to the terminals of motors, transformers and other loads. In this manner the network avoids distributing the reactive power absorbed by load. Individual power factor correction capacitors reduce additional losses caused by cable and transformer coil heating, and allows for [...]
Low Voltage Capacitor Banks – Automatic
Controllix Low Voltage Capacitor Banks provide a cost-effective, user friendly, reliable solution for power factor correction. They are a more efficient alternative to individual motor capacitors, especially in large industrial facilities. Controllix units are designed to provide power factor correction with a single installation on the main plant bus [...]
Medium Voltage Capacitor Banks – Fixed
When bulk power factor improvement is needed and there are no concerns regarding high ambient temperatures or harmonics, fixed capacitor banks are ideal. Without switching or extensive monitoring features that are typically found on automatic banks, cost and lead time are kept to a minimum. This rapid response, combined with [...]
