Active Harmonic Filters (AHF) Harmonic currents are caused by non-linear loads connected to the distribution system. A load is said to be non-linear when current it draws does not have same wave shape as the supply voltage. The flow of harmonic current through the system impedances causes voltage distortion in the distribution system. Following are … Read more
Some Good Practices in Lighting Installation of energy efficient fluorescent lamps in place of “Conventional fluorescent lamps : Energy efficient lamps are based on the highly sophisticated tri-phosphor fluorescent powder technology. They offer excellent colour rendering properties in addition to the very high luminous efficacy. Installation of Compact Fluorescent Lamps (CFLs) in place of incandescent … Read more
