Electronic Ballasts - Lightline Electronics

... Until relatively recently many electronic ballasts were made without power factor correction circuits. Because of its heavily capacitive front end components, an electronic ballast puts current and voltage out of phase with one another. As a result, it typically has a power factor of 0.6 or less, me ...

... current begins to rise due to the finite resistance R in the circuit. Note that at these early times, the inductor simply acts like a piece of wire with a very small resistance, which we can neglect. The initial condition on the current is therefore I(0)=0, which means that the voltage drop across t ...

Surge protector



A surge protector (or surge suppressor) is an appliance/device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or by shorting to ground any unwanted voltages above a safe threshold. This article primarily discusses specifications and components relevant to the type of protector that diverts (shorts) a voltage spike to ground; however, there is some coverage of other methods.The terms surge protection device (SPD), or transient voltage surge suppressor (TVSS), are used to describe electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems, for the purpose of protecting against electrical surges and spikes, including those caused by lightning. Scaled-down versions of these devices are sometimes installed in residential service entrance electrical panels, to protect equipment in a household from similar hazards.Many power strips have basic surge protection built in; these are typically clearly labeled as such. However, power strips that do not provide surge protection are sometimes erroneously referred to as ""surge protectors"".
