The CPI plus device is a capacitive voltage indicator for permanent monitoring of voltage presence of all 3 phases in
electrical equipment. Two basic alternatives are available: A standard device with visual indication of voltage condition as
well as a version with a built-in relay to allow remote monitoring and further use of signals. The indicator contains a LRM
interface to check functionality and phase sequence. The CPI+ combines proven and reliable technology at reasonable
cost.
