Introducing the Checkvolt and Voltage Vision Indicators
The ChekVolt Non-Contact Enclosure Voltage Portal reduces arc flash risks and increases electrical safety by providing maintenance personnel a no-touch voltage portal on the outside of grounded metallic electrical enclosures. The ChekVolt® interface, installed on an electrical panel, allows maintenance people to use a non-contact voltage detector 'pen' to check line voltage before and after they open the main disconnect.
The ability to pre-verify electrical isolation before opening a panel puts an additional safety measure between electricians and hazardous voltage. Standard yellow nameplates help remind personnel to pre-verify every voltage point before accessing the panel interior.
Maintenance people carry non-contact voltage detector 'pens' to quickly verify the presence of voltage in a conductor. These devices beep or flash in the presence of voltage.
The ChekVolt simply extends the line voltage from the main disconnect (or other voltage source) through a wire into an encapsulated non-metallic assembly fastened to the enclosure exterior.
The ChekVolt interface installs into a 1/2" (13mm) drilled hole. All nameplates simplify field installations with drilling locator tabs. Install Qty (3) R-1A for 3-phase applications.
The VoltageVision® R-1VH / R1VL Medium Voltage Indicator increases safety for workers performing mechanical or electrical maintenance on medium voltage equipment by helping to ensure isolation of electrical energy. These indicators flash with enough illumination to allow safe viewing from outside the enclosure through an access window (IR window) on a medium voltage starter, transformer, switchgear and other power distribution equipment.
Built for long-life and reliability with solid-state LEDs and flame-rated material, the Medium Voltage Indicators are available in packages of 3 (one per phase) in two voltage categories. Capacitive coupling between the Medium Voltage Indicators and earth ground provide a means of completing the flashing circuit without a hardwired ground connection, which provides enough energy to flash the LEDs. Capacitive coupling also provide high surge immunity and electrical installation integrity. The amount of energy transferred to the Medium Voltage Indicator through capacitive coupling varies, and therefore determines its flash rate and intensity. The key factors include the line voltage, the distance between the adjoining phases, and the size and distance of the ground plane (enclosure or other). Because of this, the Medium Voltage Indicator with a flash rate optimized for applications on voltages between 2KV and 15KV are sold under the part number R-1VL. The Medium Voltage Indicator optimized for applications on voltages between 15KV and 43KV are sold under the part number R-1VH.
