atmospheric inversion
A temperature inversion in the atmosphere in which the temperature, instead of falling, increases with height above the ground. With the colder and heavier air below, there is no tendency to form upward currents and turbulence is suppressed. Inversions are often formed in the late afternoon when the radiation emitted from the ground exceeds that received from the sinking sun. Inversions are also caused by katabatic winds, that is cold winds flowing down the hillside into a valley, and by anticyclones. In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high level dischargers, hence the case for high stacks. Furthermore, high level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing. (Source: GILP96)

Phase sequence protection
Where an incorrect phase sequence of the supply voltage can cause a hazardous situation or damage to the machine, protection shall be provided.

NOTE Conditions of use that can lead to an incorrect phase sequence include:
– a machine transferred from one supply to another;
– a mobile machine with a facility for connection to an external power supply.
[IEC 60204-1-2006]

Защита от неправильного порядка чередования фаз
Защита от неправильного порядка чередования фаз питающей сети должна быть выполнена в тех случаях, когда неправильное чередование может привести к возникновению опасной ситуации или к повреждению машины.

Примечание. Неправильный порядок чередования фаз сможет возникнуть в процессе эксплуатации в следующих случаях:
- при переключении машины с одного источника питания на другой;
- при подключении мобильной машины, оснащенной собственным средством подключения, к внешнему источнику питания.
[Перевод Интент]

When the LTM R controller is connected to an expansion module, phase reversal protection is based on voltage phase sequence before the motor starts, and on current phase sequence after the motor starts.
[Schneider Electric]

Если контроллер LTM R соединен с модулем расширения, то защита от неправильного порядка чередования фаз проверяет перед пуском электродвигателя порядок чередование фаз напряжений, а после пуска – порядок чередования фаз токов.
[Перевод Интент]

tornado
A rapidly rotating column of air developed around a very intense low-pressure centre. It is associated with a dark funnel-shaped cloud and with extremely violent winds (>300km/h) blowing in a counterclockwise spiral, but accompanied by violent downdraughts. The precise mechanisms are not fully understood but the following atmospheric conditions appear to be necessary for tornado development: a layer of warm moist air at low altitude; a layer of dry air at higher altitude with an inversion of temperature at about 1.000 m; a triggering mechanism, usually in the form of an active, intense cold front or solar heating of the ground which will create a vortex.
