Metrohm LLT-11KVKIT High Voltage Live Line Tester

The Live Line Tester Kits (LLT) 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 housed within a heavy-duty carry case with secure compartments. Individual kits are available for system voltages of 3.3kV, 6.6kV, 11kv, 13.8kV, and 33kV (50/60Hz). Made from high-quality fiberglass rods and polycarbonate moldings the equipment is suitable for both indoor and outdoor use – including wet conditions. The equipment has been designed to operate within the temperature range: – 25˚C to + 50˚C.

Overhead Line Testing

Switchgear Testing

Designed to comply with the requirements of IEC1243 part 2, the LLT uses long-established techniques for high voltage measurement. All readings are displayed on an analog 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.
