ATS-GAA series automatic loading transfer panel is the standard configure of emergent power system. The panel detects the voltage and frequency of civil electricity timely. While there is something wrong, such as high voltage, low voltage, phase missing, electricity cutting off, etc., it will signal to start the generator set automatically; then the generator set starts as soon as receiving the signal; ATS-GAA panel controls the switch to run the power when the generating of electricity is balanced;  after the civil electricity resumes balanced, ATS-GAA panel will control the switch from generating electricity to civil electricity after prolonged confirmation, resumes the civil electricity; simultaneity, it controls the generator set to shut down after cooled. To-and-fro, makes the automatic double-circuit system comes to be true.
The key technique of ATS-GAA panel is how to achieve the detection of the civil electricity's state (the control gauge), how to control the switch from the generating electricity to civil electricity.
