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 [...]
Guide for Plant Engineers
Power Factor and Harmonics Power factor is defined as real power, the power that does work, divided by apparent power, the power that must be delivered in order to get the work done. Real power is measured in kilowatts (kW) and apparent power is measured in kilovolt amps (kVA.) Power [...]
Metal Enclosed vs. Rack-Mounted Capacitor Banks
A Metal-Enclosed Bank comes fully assembled, tested, and ready for interconnection. No field assembly is required. Therefore installation costs and problems associated with mistakes during installation are very low. Maintenance costs for Metal-Enclosed Banks are low. Special equipment such as bucket trucks and hot-line tools, as well [...]
