2014
IOSR Journal of Applied Physics
Preserved Fulltext
This paper presents the design and development of microprocessor based AC line voltage recorder. It can keep the record of line voltage for twelve hours at an interval of an half minute. Variac with half-wave rectifier and a Z-80 microprocessor based trainer kit is used as the sensor and interfacing the circuit respectively. It can sense the line voltage from 0-250V. The product would be handy portable and commercially viable.
