This live line indicator is made for use on high voltage overhead lines and third rail systems up to 3000V DC.
When hooked onto a line and correctly earthed the LLI-3000DC is used to evaluate the voltage status of the line it is attached to. It does this by evaluating if voltage is passing through the system and if it does detect voltage the LLI-3000DC used bright red LED indicators and a 70dB audible tone to instantly alert the person using the live line tester of the presence of live voltages.
The length of the rods are designed to allow the user to easily reach an overhead line without getting too close. The rods are also compatible with various different adaptors - including the supplied star adaptor - to allow testing on different line types.
The Metrohm LLI range is also available in 750V and 3000V DC models. All models are only suitable for use on DC systems.
