Metrohm DC LLI1500V

The Metrohm High Voltage DC Live Line Indicator (LLI-1500) 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 LLI1500 gives both visual (high intensity flashing red LED’s) and audible (70dB) alarm should a conductor under test indicate as live. FEATURES Designed for use on overhead conductors of light rail systems. Determines whether a conductor is de-energised. Clear visual and audible indication. Designed to be mounted on insulated operating rods. Metrohm LLI1500 Specifications Voltage Ranges 1500 V DC. Std Thresholds 500 V DC (can be adjusted for particular requirements).
