e²TANGO® ATS Automation

Controllers for automatic transfer switch with auto re-transfer – e²TANGO® ATS have been developed on the base of e²TANGO® controllers and supports the same features and functions. They are available in various configurations for LV, MV and HV network. Standard version allows implementation of automation in 1 or 2-sectional switchgears.
-explicit, implicit stand-by, automatic selection (based on the configuration of switches)
-fast and slow mode
-measurement of 6 phase voltages on the bus-bars and two wire voltages on the top side of power supply transformers or power lines,
-optional measurement of currents,
-optional re-transfer to the normal power supply,
-optional automatic locking of automation after operation,
-two communication ports RS485/optical fibre, Ethernet link to cooperate with the dispatch centre or engineering link. Support for Modbus RTU, Modbus TCP, IEC870-5-103, DNP3.0, Canbus, Profibus protocols.
-event recorder for 1000 events, recording all automation-, interlocks operations and emergency states. 
 -disturbance recorder recording the measured voltages with configurable recording time after triggering the recorder.
The controller in the standard version supports the 2-section switchgear with two transformers or two supply lines, with sections connected by a bus-bar connector or 1-section switchboard with two supply lines. In the case of 2-sectional switchboard the controller performs explicit and implicit automation with optional re-transfer to the normal power supply.

In addition to standard solutions for automatic transfer switch with auto re-transfer we offer to develop special versions, tailored to individual customer needs. Dedicated systems are created in close cooperation between the R&D department and the client.
Examples of custom solutions:
-switchgear with three sections (e.g. 3 power supplies, 2 coupling)
-dedicated switching algorithms
-current measurements and analysis of power supply load.
