The HVD-Q-2 LED Display Live Line Switchgear Indicator is an advanced non-contact high-voltage live detection device designed to enhance safety in power systems. Utilizing an integrated three-phase continuous display, this innovative instrument accurately tests voltage loss in medium-voltage switchgear without direct connection to high-voltage live components. It senses electric field signals, reflecting the charging status of high-voltage equipment with a reliable locking function.

Compliant with IEC 61243-5 and IEC 62271-213 standards, the HVD-Q-2 is ideal for indoor high-voltage electrical equipment, preventing accidental access to live areas and electrical misoperations. Key features include flashing display alerts, sound alarms, self-check capabilities, and a forced locking circuit that works in conjunction with electromagnetic locks and microcomputer anti-misoperation functions. The device is widely applicable in 7.2kV to 40.5kV electrical equipment, ensuring safety during operations like grounding switch management.
