Description: Three-phase alternating current widely used in the national economy, the circuit flow of traffic on the industrial production of paramount importance. For some causes of a phase AC power, will cause major economic losses, and thus the line detection is very necessary. SCM-phase long-range three-phase alternating current alarm to 8051 as the core, non-stop for three-phase circuit testing. When a phase power line, not only can be short-range sound and light alarm, sound alarm can also be remote.
