T&R LLT-11kV Live Line Tester Kit
The T&R LLT-11kV Live Line Kit enables safe detection and measurement of live high voltage circuits on overhead lines, substations, and switchgear systems. Engineers can confirm voltage presence and compare phases while maintaining a safe working distance with insulated fibreglass rods.
A robust analogue meter supports reliable measurement and rotates through 240 degrees to provide clear viewing from different working positions. This allows operators to monitor readings easily while carrying out testing tasks in the field.
Accurate Live Line Measurement
The T&R LLT-11kV Live Line Kit measures live voltage up to 11kV AC and supports extended measurement capability up to 15kV when used with the internal resistor chain. Consequently, technicians can verify energised circuits and confirm phase relationships on overhead conductors.
Additionally, the kit includes a battery powered proving unit which allows the tester to be checked before and after use. This ensures confidence in measurement accuracy and helps confirm full scale meter deflection during verification.
Built for Field Conditions
Durable fibreglass rods and polycarbonate mouldings allow the T&R LLT-11kV Live Line Kit to operate in demanding electrical environments. The equipment can be used indoors or outdoors and remains suitable for both dry and wet working conditions.
Furthermore, the tester operates within a wide temperature range from -25°C to +50°C. A heavy duty carry case with organised compartments keeps all components protected and ready for transport between job sites.
