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.
