In the electrical plants, where a high reliability is required from the power supply

source because the operation cycle cannot be interrupted and the risk of a

lack of power supply is unacceptable, an emergency line supply is indispensable

to avoid the loss of large quantities of data, damages to working processes,

plant stops etc.

For these reasons, transfer switch devices are used mainly for:

• power supply of hotels and airports;

• surgical rooms and primary services in hospitals;

• power supply of UPS groups;

• databanks, telecommunication systems, PC rooms;

• power supply of industrial lines for continuous processes.

ATS010 is the solution offered by ABB: it is an automatic transfer switch system

with micro-processor based technology which allows switching of the supply

from the normal line (N-Line) to the emergency line (E-Line) in case any of the

following anomalies occurs on the main network:

• overvoltages and voltage dips;

• lack of one of the phases;

• asymmetries in the phase cycle;

• frequency values out of the setting range.

Then, when the network standard parameters are recovered, the system

switches again the power supply to the main network (N-Line).

ATS010 is used in systems with two distinct supply lines connected to the

same busbar system and functioning independently (“island condition”): the

first one is used as normal supply line, the second is used for emergency power

supply from a generator system. It is also possible to provide the system with a

device to disconnect the non-priority loads when the network is supplied from

the E-Line.
