AGC – the true meaning of multi mains
The updated AGC Automatic Gen-set Controller handles an astonishing 56 breakers and is immune to a failing master controller due to the integrated multi-master principle. Combined with an exhaustive list of other new features, it will simply enable you to do things you would have never thought possible.
Up to 16 mains incoming, 16 mains breakers, 16 tie breakers, 8 bus tie breakers, 16 generators and 16 generator breakers; if this fits the description of your application, you might want to continue reading.
All 56 breakers can be synchronised and communication between the controllers will be fully redundant – all by choice and without extra cost. Moreover, the AGC offers selectable mains priority and parallel operation.

he Summarize Measurement and Protection Unit (SMPR-1) has been designed to measure the line and ground RMS currents and supply RMS voltages under normal conditions or under disturbances. The voltage and current signals are sensed throughout potential transformers (PT) and current transformers (CT) from each line. This information is internally processed by the microprocessor, to take the current protection actions defined under ANSI, IAC or IEC standard. Additionally the operational conditions of the breaker or disconnector are also signalized. The different functions provided by the SMPR-1 may be classified into the following groups:
Applications:
* Primary and backup protection for power plants, utility and industrial distribution systems.
* Protection of transformers, overhead lines, cables and generators.
* Permits the opening of the switch/disconnector within the limits of its capacity, those identifying the excess (e.g. straight short-circuits), leaving the circuit interruption to the back-up fuses.
