ELECTRIC LINEMAN PROTECTIONUSING KEYPADAND GSM BASEDCIRCUIT BREAKER

Abstract

Now a days we see fatal electrical accidents to theelectric line man are increasing during the electric line repair due to the lack of communication and co-ordination between the maintenance staff .In order to avoid such accidents, the breaker can be so designed such that only authorized person can operate it witha password. The system is fully controlled by the 8 bit microcontroller of At megafamily. The password is stored in an EEPROM, embedded inthe microcontroller andcan be entered through a keypad or a GSM modulewith a registered a mobile only. A relay is used to open or close circuit breaker, which is indicated by a lamp. Any wrong attempt to open the breaker (by entering thewrong password) will not be entertained.
