Harmonics in power system. In an electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system, produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated magnetic devices. Harmonic frequencies in the power grid are a frequent cause of power quality problems. Harmonics in power systems result in increased hea...

A capacitor bank is a grouping of several identical capacitors interconnected in parallel or in series with one another. These groups of capacitors are typically used to correct or counteract undesirable characteristics, such as power factor lag or phase shifts inherent in alternating current (AC) electrical power supplies. FEATURES: Power factor correction by multi step design Standard & detu...

Power Quality Solutions and Energy Savings One of the most significant changes in the Power Quality industry in the past five years is the method of selling Power Quality solutions. Originally, Power Quality solutions were sold as an insurance policy to avoid potential damage from power disturbances such as transients,voltage sags, interruptions or harmonics. Today, many Power Qu...

Benefits by installing power factor correction systems? Power factor correction systems provide much benefit: Reduced electricity utility bills Your electric utility provides working (kW) and reactive power (kVAR) to your plant in the form of apparent power (kVA). While reactive power (kVAR) doesn’t register on kW demand or kW hour meters, the utility’s transmission and distribution system must be...

Power capacitors are very beneficial in power networks. They provide reactive power required by motors, transformers, etc. This increases the transmission capacity and reduces losses thanks to higher power factors. They enable the power factor targets of the utilities to be met. Power capacitors and series reactors are also a key component in various filter solutions that reduce harmonic cont...

Energy demand is anticipated to be double by 2030. CO2 emissions should be halved to avoid global warming acceleration. Both issues place a major challenge on the generating capacity of all utilities, and on us as electricity end users. Energy efficiency becomes more than a cost issue today. It becomes part of the journey to ensure energy availability and preserve the environment in the future. Ma...
