LLT-11kV Kit

Live Line Testers

The Live Line Testers (LLTs) have been specifically designed to perform measurements for both live voltage testing and phasing on overhead lines, in substations and within switchgear compartments.

Each Live Line Tester kit comprises of 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
  • 2 overhead line adaptors
  • Proving Unit with batteries
  • Polymer Cleaning Kit
  • Instruction manual

*Individual items can be supplied separately

Designed to comply with the requirements of IEC1243 part 2, Live Line Testers use long established techniques for high voltage measurement. All readings are displayed on an analogue meter – the housing of which can be rotated through 240 degrees to ensure a perfect viewing position.

Live Line Testers are made from high quality fibreglass rods and polycarbonate mouldings. Equipment is suitable for both indoor and outdoor use, including wet conditions. This instrument has been designed to operate within the temperature range: -25˚C to + 50˚C.

Individual kits are available for system voltages of 3.3kV, 6.6kV, 11kv, 13.8kV and 33kV (50/60Hz). A battery operated proving unit allows the equipment to be tested before and after measurements have been made and can also be used to check full scale deflection on the meter.

Adaptors are available to allow Bowthorpe Rods to be connected for testing of raised conductors and a Repeater Station can be supplied to replicate meter readings at ground level. Space is reserved in the carry case for such accessories.

This product and all its variants are available in the United Kingdom through our partners, AcutestAlpha ElectronicsCuthbertson LairdNorwich Instrument Services, and PASS Ltd. Alternatively, you can contact us direct by phone or request a quotation through our website.
