The High Voltage DC Live Line Indicator (LLI-750) is a battery operated electronic unit that has been specifically designed to test DC systems - with particular relevance to Mass Transit Railway (Metro) & Tram based models.
Although usually applied to overhead catenaries they can also be used on 'third rail' installations. Proving that the system is de-energised – and can thus be safely earthed - is important to both maintenance staff and system security. The DC LLI-750 gives both visual (high intensity flashing red LED’s) and audible (70dB) alarm should a conductor under test indicate as live.
