An unregulated DC supply will produce a lower output voltage. The output voltage ripple will decrease in line with the usually reduced load current. In a cathode-ray tube television, the reduced output voltage will make the screen image smaller, dimmer and fuzzier.
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
A "severe" solar storm could make the northern lights visible in the U.S. farther south than usual while also posing the potential to disrupt modern technology, according to the National Oceanic ...
Vehicle lights provided the only illumination during the 2009 Ecuador electricity crisis.. A power outage, also called a powercut, a power out, a power failure, a power blackout, a power loss, a blackout or a power drought — is the loss of the electrical power network supply to an end user.
This is the most commonly used surge waveform for most applications, often referred to as a "1.2/50-8/20 μs" surge. Alternatively, for outdoor telecommunication networks that experience a higher surge level, the standard also defines a more energetic generator with a 10/700 μs voltage waveform and a 5/320 μs current waveform.
The best time to see the northern lights is between 10 p.m. and 2 a.m. local time.
Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...
In Canada, a severe thunderstorm is defined as having wind gusts of greater than 90 km/h (56 mph), hail with a diameter of greater than two centimetres (0.79 in), rainfall rates of greater than 50 millimetres (2.0 in) in one hour or greater than 75 millimetres (3.0 in) in three hours, or tornadoes.
