thermal limit
thermal limit
[′thər·məl ′lim·ət] (electricity)
A limit on the power carried by an electric power system that results from the heating effects of the power carried by the devices.

Although the lethal thermal limit often decreases with extended exposures, possibly biasing this comparison toward finding lower larval tolerances, two lines of evidence suggest that this cannot account entirely for this result.
At this point, there is a cellular transition from aerobic to anaerobic metabolism; therefore, the critical thermal limit becomes a match when the aerobic scope is close to zero.
In addition, the combination of planetary and helical-bevel gear units translates into an optimum power/weight ratio, in addition to an improved thermal limit rating by means of a shared oil chamber.
The 40V, 2.1A low dropout linear regulator (LDO) includes current monitoring with externally settable current limit and temperature monitoring with external control of thermal limit temperature.
This means that, in practice, designs can no longer be made based on an assumed power thermal limit; instead, thermal design has to be based on how the product will be used, and power has to be throttled back if the product becomes too hot when used at the limits of its application.
ii) No element has violated its thermal limit during any contingency.
Nevertheless, if the range of the fluctuation became very great, egg development should be inhibited if daytime temperatures rose to the upper thermal limit or nighttime temperatures decreased to the lower thermal limit of development.
For comparison among species, a thermal limit was taken at which more than 70% of the embryos reached successfully the end-point of the experiments (see above), as a more restrictive parameter than the commonly used 50% of survival of embryos [1, 9, 20].
This same product also has an upper temperature thermal limit of +125 deg C, which ensures that internal surfaces of pipework, tanks and vessels can be safely subject to steam or high temperature chemical cleaning without detriment to the insulation materials.
NRC regulations set a fuel thermal limit of 2,200 degrees Fahrenheit for "peak cladding temperature" under predicted loss-of-coolant accident conditions.
A seal's thermal limit can, however, be extended to meet almost any pump system requirements by upgrading the seal material to a thermopolymer or PTFE.
In other words, the desired power flow in the interconnection is greater than the thermal limit. Power of overload is usually calculated for the initial operating state:
