As well as describing the main features of the ATS, this White Paper gives particular attention to the automatic commutation concept applied in low voltage plant engineering configurations.
The analyised configurations include:
- a transformer for the main line and a generator for the emergency line
- a transformer for the main line and another transformer for the emergency line
- use of a bus tie to exclude non priority loads (with ATS022 only)
- use of a bus tie to manage two independent supply lines (with ATS022 only).
Moreover, an application example is given to explain and add some more information about the connections between the components involved by transfer switching (auxiliary contacts, motor operating mechanism, etc.) and the ATS unit. To guarantee proper switching, further indications regarding time delay settings are given.
The White Paper "ATS021-ATS022 Automatic transfer switching" (code 1SDC007408G0201) in English version is now available here on Voltimum as a Flipbook.
