New Live Line Tester for Electrical Rail Systems
27th May 2010

The LLT live line voltage indicator has been designed to ensure safe working on third-rail electrified railway lines and systems.

The new Seaward LLT two pole voltage detector enables service engineers, maintenance personnel and technical staff to verify that conductor rails have been isolated from the power supply before maintenance or inspection work commence on rail track systems.

The new unit has been designed specifically for the safe and practical detection of voltages on electrified rail systems above a threshold level of 300V DC up to a maximum of 1100V DC. Ultrabright red LEDs and a polarising filter built into the handle section of the tester make the voltage indication clearly visible in all working environments and conditions – even in bright sunlight.

Designed and manufactured in compliance with international safety standard BS EN61243-3, the live line test unit is totally encapsulated in a shock resistant high impact rugged enclosure and is IP65 rated. The tester is also equipped with PVC hand guards and high visibility cable.

Also available from Seaward is a special battery powered proving unit for self-test proof of Live Line Tester performance before and after use. The compact and highly portable unit incorporates a neon active indicator for simple and immediate on-site verification of tester functionality – enabling line testing and any subsequent maintenance work to be undertaken safely and without hazard.

A special carrying case for the Live Line Tester and LLT Proving Unit is also available.

The introduction of the new live line tester for railway service applications expands the Seaward range of voltage indicators and safety testing equipment that includes a comprehensive range of neon and digital high voltage indictors, safe discharge units, neon and digital phasing equipment, insulator leakage detectors and current clamps.
