摘要:Abstract(#br)The energy consumed by artificial lighting represents a vast amount of total energy consumption of a building. LED luminaires combine many advantages and they are considered a prominent lighting technology. The utilization of miscellaneous optimization methods i...

摘要:Abstract(#br)Commonly used compact fluorescent lamps (CFLs) with electronic gear are characterized by extremely distorted current, with total harmonic distortion (THD) usually exceeding 100%. That is why they cause a significant voltage distortion in electrical installations...

摘要:Abstract(#br)Using some simple physics and “system” considerations, the instantaneous light intensity function ψ ( t ) of a fluorescent lamp fed via a regular ballast from the 50–60 Hz line is argued to be ψ ( t ) = ψ min + b p ( t ) , where p ( t ) is the instantaneous...

摘要:The influence of solid insulating barriers to the impulse strength of air gaps has been investigated by few researchers. It is well known that thin insulating materials increase considerably the breakdown voltage, sometimes two to three times. Some researchers performed thorough ...
