Detection  of AC mains voltage without contact

 

 

                              

Security is prime concern in our day-to-day life. Everyone wants to be as much as secure as to be possible. Thus, to be secure from short circuit or any other electrical disputes, Failure in mains AC supply must be detected.

The Contactless AC mains voltage detector is a circuit which is based on a decade counter. It can detect the voltage without the need to remove the insulation from the conducting wires.

This report discusses about the process to make the contactless ac mains voltage detctor, its working principle, the pros and cons of this system and its areas of application.

All the topics have been illustrated with clear diagram and simple language is used throughout the report to facilitate easy understanding of the concept.
