It provides a clear visual warning and helps reduce the risk of electric shock, misoperation, and equipment damage in daily electrical work.<\/p><hr data-start=\"559\" data-end=\"562\" \/><h2 data-start=\"564\" data-end=\"604\">How Does it Work?<\/h2><p data-start=\"605\" data-end=\"1024\">A live line indicator works by using <strong data-start=\"642\" data-end=\"683\">capacitive voltage sensing technology<\/strong>. One side of the sensor connects to the high-voltage conductor, while the other is grounded. The voltage signal is transferred through an <strong data-start=\"822\" data-end=\"860\">epoxy-resin encapsulated capacitor<\/strong>, and the energized status is shown through <strong data-start=\"904\" data-end=\"934\">three-phase LED indicators<\/strong>.<br data-start=\"935\" data-end=\"938\" \/>For cable bushings, a <strong data-start=\"960\" data-end=\"988\">24pF dedicated
