The LLT-6.6kV Live Line Tester Kit is specifically designed to perform measurements for both live voltage testing and phasing on overhead lines, in substations, and within switchgear compartments. This comprehensive kit includes all the necessary components to effectively carry out these tests.

The kit comprises the following components housed within a heavy-duty carry case with secure compartments:

  • Live line tester with earth lead
  • Phasing rod with phasing lead
  • 2 extension rods
  • 2 bend end adaptors
  • Proving Unit with batteries
  • 2 overhead line adaptors
  • Polymer Cleaning Kit
  • Instruction manual

*Individual items can be supplied separately.

Designed to comply with the requirements of IEC1243 part 2, the LLT-6.6kV Live Line Tester kit utilizes long-established techniques for high voltage measurement. Moreover, all readings are displayed on an analogue meter – the housing of which can be rotated through 240 degrees to ensure a perfect viewing position.

Constructed from high-quality fiberglass rods and polycarbonate mouldings, this instrument is suitable for both indoor and outdoor use, including wet conditions. Additionally, it operates within a temperature range of -25˚C to +50˚C.

While the maximum voltage is 6.6kV, the measuring range can extend as high as 10kV, with a resistor chain of 52.5MΩ. Notably, a battery-operated proving unit allows the equipment to be tested before and after measurements have been made. It can also be used to check full-scale deflection on the meter.

To enhance flexibility, adaptors are available to allow Bowthorpe Rods to be connected for testing of raised conductors. Furthermore, a Repeater Station can be supplied to replicate meter readings at ground level. Importantly, the carry case includes reserved space for such accessories.

Our partners, including AcutestAlpha ElectronicsCuthbertson LairdNorwich Instrument Services, and PASS Ltd, offer the LLT-6.6kV kit in the United Kingdom. Additionally, if based outside Great Britain, kit can be ordered through our worldwide distribution network.
