4.2.3.2 Physical degradation and failure (e.g. cycling) The physical degradation of composite insulators occurs via numerous and sometimes competing mechanisms. The utility pole case study thereafter shows the diversity of environmental loads responsible for degradation of high voltage line components. Ca...
Google Share on Facebook disruptive discharge (redirected fromElectrical breakdown) Also found in:Encyclopedia,Wikipedia. disruptive discharge n (General Physics) a sudden large increase in current through an insulating medium resulting from failure of the medium to withstand an applied electric field ...
Otherwise, electric shocks or fire may occur. Non-standard and improper operations may result in fire or electric shocks. Prevent foreign matter from entering the equipment during operations. Otherwise, equipment short-circuits or damage, load power derating, power failure, or personal injury may ...
Where mechanical failure or abnormal operation of machinery or equipment might cause such explosive or ignitable mixtures to be produced, and might also provide a source of ignition through simultaneous failure of electrical equipment, through operation of protection devices, or from other causes, or ...

thus increasing the cost of time and the probability of failure. Moreover, photosensitive proteins are activated by visible light at a power density of ~300–700 mW/cm2, which may damage the nerve due to the thermal effect of the excitation light. Instead of electrode implantation, optical...
Neural computing, guided by brain-inspired computational frameworks, promises to realize various cognitive and perception-related tasks. Complementary metal–oxide–semiconductor-based computing machines use orders-of-magnitude more computational resourc
This smaller sized fraction has been closely associated with increased respiratory disease, decreased lung functioning, and even premature death, probably due to their ability to bypass the body’s trapping mechanisms, such as cilia in the lungs and nasal hair filtering. Some of the diseases linked...
One very important consideration in controls system design, both mechanisms and cables, is the prevention of jamming. This is typically one of the worst failure conditions for a control system because it often leads to a hardover surface. Hardover is a condition when, uncommanded, the flight ...
In accordance with another preferred embodiment of the invention various cardiac parameters are controlled via inherent cardiac feedback mechanisms. In one example, the heart rate is controlled by applying a non-exciting voltage to pacemaker cells of the heart, at or near the SA node of the ...
