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 [...]
Medium Voltage Capacitor Banks: Multi-Step
Controllix Medium Voltage Multi-Step Capacitor Banks provide accurate control of power factor from light load conditions through heavy load conditions. Banks feature a standardized design that is easily equipped with additional stages for future load growth. Banks come fully assembled and ready for interconnection. Equipment is fully compliant with the [...]
Controllix Fortifies a Coastal Utility with Metal Enclosed Capacitor Banks
Summary: Controllix Corporation transitioned a coastal utility from using open rack style capacitor banks to their advanced metal-enclosed capacitor banks. This change notably improved the utility's resilience against weather-related events such as hurricanes and reduced wildlife interference. The metal-enclosed design also incorporated key interlocking features, enhancing safety measures for maintenance [...]
Controllix Delivers Cost-Efficient and Energy-Smart Solutions to a Midwest Utility
Summary: A Midwest utility faced the need to replace an outdated 34.5kV, 1200A fixed breaker used daily for switching a remotely located 10.8MVAR capacitor bank. Controllix Corporation offered an innovative solution: a capacitor switch with a pre-insertion resistor to limit inrush current. The switch not only met the utility's operational [...]
How Controllix’s Metal-Enclosed Harmonic Filters Transformed a Midwest Foundry
Summary: Controllix Corporation was commissioned by a Midwest foundry to provide multiple metal-enclosed harmonic filter equipment, tailored with 5th and 11th harmonic tuning frequencies. A high-pass resistor was also included in the 11th harmonic filter. The successful deployment of these custom filters led to a reduction in the foundry's energy [...]
Controllix Rapidly Outfits 36 Substations with 76 Custom Capacitor Banks
Summary: Controllix Corporation faced a monumental task when a large Midwestern utility required 76 large metal-enclosed capacitor banks across 36 substations, all within a five-month timeframe. Customizing 11 different equipment designs to meet substation specifications, Controllix met the challenge head-on. Through meticulous coordination across multiple departments, the company not only [...]
Controlling System Voltage
Without capacitors, the voltage drop across a system is calculated as: […]
Seismic Certification of Capacitor Equipment
Controllix metal-enclosed capacitor banks are designed for withstanding the most violent of natural phenomena, including earthquakes and wind storms. Specifically, Controllix equipment is certified for Zone 4 seismic compliance. The results of studies (available upon request) indicate that Controllix assemblies are qualified to withstand the effects of gravity dead load and [...]
Air Core vs. Iron Core Reactors
Introduction At the medium voltage level, 2.4kV through 34.5kV, harmonic filters are often designed, specified, and manufactured with either Iron-core or Air-core reactors. The preference for one reactor over the other may be from experience, familiarity, misconception, or some good technical reason. This document should help in presenting the major [...]
