Another term we adopted to describe some of our problems was "glitch". Literally, a glitch is a spike or change in voltage in an electrical circuit which takes place when the circuit suddenly has a new load put on it. You have probably noticed a dimming of lights in your home when you turn a switch or start the dryer or the television set.
Campaign group Electrical Safety First says flickering lights and sulphuric smells in the home mean it is time to call an electrician
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.
Electric power quality is the degree to which the voltage, frequency, and waveform of a power supply system conform to established specifications. Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady AC frequency close to the rated value, and smooth voltage curve waveform (which resembles a sine wave).
Similar to fluorescent lights, HMIs present problems with color temperature when used for film or video lighting applications.Unlike incandescent-lighting units, which are blackbody radiators limited to a theoretical maximum of 3680 K (the melting point of tungsten), HMI lamps, like all gas discharge lighting, emit the emission spectral lines of its constituent elements, specifically chosen so ...
WEST LONG BRANCH - Lights flickering on and off, seemingly at random. The sound of organ music echoing. Unexplained cold spells and visions. Eerie experiences in the elevators, where tragedy ...
Before and after photos of the deadly wildfires in the Los Angeles area have sent tens of thousands scrambling for safety and decimated neighborhoods.
Flicker noise is a type of electronic noise with a 1/f power spectral density. It is therefore often referred to as 1/ f noise or pink noise , though these terms have wider definitions. It occurs in almost all electronic devices and can show up with a variety of other effects, such as impurities in a conductive channel, generation and ...
