Lli 750V - 3000V DC Live Line Indicators
The High Voltage DC Live Line Indicator Kit (LLI) is a battery operated electronic unit that has been specifi-cally designed to test DC systems, with 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 safe-ly earthed, is important to both maintenance staff and system security.
Features: • For use on DC high voltage overhead lines up to 3000V DC • Earth lead and clamp attached to long-length handle • Red LED indicators when voltage is detected • Loud 70dB alarm when voltage is detected • Audible indication: Buzzer, 3.1 kHz tone, modulated @ 2Hz • Can be used on third rail installations • Battery check function • Standard Thresholds: 250V / 500V / 1000V DC • Resistor Chain: 1.5MΩ / 3 3MΩ / 6 6MΩ • Operating time: 5 minutes nominal
