LQHV-550 Wireless Insulator Voltage Distribution Detection System

Live Line Insulator Condition Assessment

This EMC-certified wireless detector identifies failed insulator discs on energized lines up to 1000kV. The 100m transmission range and articulated probe enable safe testing of hard-to-reach suspension strings.
