An arc flash, also called a flashover, is a sudden electrical explosion or discharge that happens when electric current travels through the air from one conductor to another. When an arc flash occurs, the results can be extremely violent, and if a person is in close proximity to the flash,...
Thanks to improving technology, power outages have become less frequent and don’t last long. While there is very little that a homeowner can do to prevent a power outage, there is much that they can do to be prepared in the event one occurs. ...
solvents, firmly installed, effectively blocking the fall of bird droppings and other foreign objects. According to the specifications of the tower, different sizes of baffles can be customized to prevent the risk of flashover breakdown caused by bird activities and ensure the safe operation of the ...
The temperature of the firing end of the spark plug must be maintained at a level high enough to prevent fouling, but low enough to prevent pre-ignition. Spark plug manufacturers refer to this as “thermal performance.” Thermal performance, or heat range of the spark plug, has nothing to ...
An application circuit configuration must guarantee that the maximum safety ratings will never be ex- ceeded during the single fault condition to prevent damage to the optocoupler or its insulation. These ratings are not normal oper- ating ratings, but values that should not be exceeded. The ...
faulty SSR turn-on. Although this false ignition does not damage the SSR as a voltage spike induced by di/dt does, it is obviously still a problem. To prevent this occurrence, an RC snubber circuit is also added to suppress the sudden rise in the voltage seen by the TRIAC (Figure ...
Similar to internal short-circuits, the appearance of gas in the gas-tight chamber of the capacitor creates overpressure which may lead to the opening of the case and leakage of the dielectric. 4. Capacitor component short-circuit A capacitor component short-circuit is due to the flashover of ...
