The HVD-T-2 3-36 KV System Phase Detector is an innovative non-contact detection device designed for high-voltage switchgear applications. This advanced unit provides continuous three-phase voltage display, ensuring the safety of power systems by accurately detecting voltage loss without direct connection to live components. It senses electric field signals to reflect the charging status of high-voltage systems and incorporates a reliable locking mechanism to prevent accidental operation.

Compliant with IEC 61243-5 and IEC 62271-213 standards, this phase detector is essential for indoor high-voltage equipment, minimizing the risk of accidental entry into live environments. Its features include a flashing display, sound alarms, self-check capabilities, and a forced locking circuit, making it ideal for various applications in 7.2kV to 40.5kV electrical networks. The HVD-T-2 is typically installed on line grounding switches and busbar voltage change grounding switches to prevent incorrect operation of charged grounding switches.
