Overview
High-Voltage Live Display Device
This non-contact high-voltage live display device is designed for medium-voltage switchgear, offering reliable voltage loss testing to ensure power system safety. It utilizes an integrated three-phase continuous display to monitor electric fields without direct connection, preventing accidental entry into live spaces. Featuring self-check capabilities, sound alarms, and forced locking circuits, it is an essential safety component for 7.2kV to 40.5kV electrical equipment.
