CVI-2R Capacitive Voltage Indicator

Information

CVI-2R is a standard-compliant capacitive voltage indicator engineered exclusively for medium voltage switchgear VDIS (Voltage Detecting & Indicating System), fully complying with IEC 62271-213:2021 international standard. It adopts capacitive coupling detection principle without galvanic connection to HV circuits, matching capacitive divider bushings to capture three-phase electric field signals from 7.2kV up to 40.5kV MV networks. This 96×48mm panel-mounted indicator integrates an adjustable C2 capacitance module to calibrate voltage division ratios, paired with a triple-phase high-definition LCD screen and dedicated self-test buttons for on-site function verification. It supports universal 85–265V AC/DC auxiliary power supply and comes with dual relay dry contact outputs for interlock, alarm and remote signal transmission. This capacitive voltage indicator delivers multi-stage voltage status judgment to guarantee maintenance safety: it identifies three working states including low voltage presence (10%~45%Un), nominal voltage present (>45%Un) and overvoltage (>120%Un), with clear lightning symbol LCD prompts for each phase. The built-in self-test function allows one-click inspection of indicator integrity before maintenance, avoiding misjudgment of dead busbars. Two-channel relay contacts output real-time voltage status signals to interlock switches, local alarms or remote SCADA platforms. Widely deployed in medium voltage distribution switchgears, power generation equipment, industrial power rooms and data center power systems, it eliminates electric shock risks by reliably confirming voltage presence/absence before equipment overhaul and switching operations.
