T&R LLT-11kV Live Line Tester Kit
The T&R LLT-11kV Live Line Tester Kit is designed for live voltage testing and phasing on overhead lines, in substations and within switchgear compartments. It detects and measures live AC voltage on circuits up to 11kV while insulated fibreglass rods allow the operator to work at a safe distance from energised conductors. The kit also supports phase comparison between overhead conductors, making it suitable for routine high-voltage field testing.
Clear readings are provided by an analogue meter housed in a unit that can rotate through 240 degrees. This adjustable viewing position helps operators monitor the meter when working from different angles or positions. For measurements beyond the primary 11kV range, the T&R LLT-11kV Live Line Tester Kit can extend its measurement capability up to 15kV when used with the internal 75 MΩ resistor chain.
Built for demanding field conditions, the tester uses fibreglass rods with polycarbonate mouldings and is suitable for indoor and outdoor use, including wet conditions. It operates from -25°C to +50°C and is supplied in a heavy-duty carry case with secure compartments for transport and storage. A battery-powered proving unit enables functional checks before and after measurements and can also be used to confirm full-scale meter deflection.
