Individual kits are available for system voltages of 3.3kV, 6.6kV, 11kv, 13.8kV and 33kV (50/60Hz).

The 33kV Live Line Tester Kits (LLT33kV) have been specifically designed to perform measurements for both live voltage testing and phasing on overhead lines, in substations and within switchgear compartments.

The kit includes all necessary components to effectively carry out these tests. All components are Metrohm LLT 33kv in usehoused within a heavy duty carry case with secure compartments. Made from high quality fibreglass rods and polycarbonate mouldings the equipment is suitable for both indoor and outdoor use – including wet conditions.

Designed to comply with the requirements of IEC1243 part 2, the LLT 33kV uses 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.

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.
