T&R Edgcumbe - Model LLT-3.3kV - Live Line Tester Kit for Overhead Line Voltage Testing
The LLT-3.3kV Live Line Tester Kit by Edgcumbe is engineered for precise measurements in live voltage testing and phasing applications primarily on overhead lines, substations, and switchgear compartments. The kit is composed of robust materials including fiberglass rods and polycarbonate mouldings, making it apt for both indoor and outdoor scenarios, even under wet conditions. It operates efficiently in temperatures ranging from -25°C to +50°C, with a measurement capacity extending up to 5kV. This device complies with IEC1243 part 2 standards and utilizes proven measurement techniques, displaying readings on a rotatable analogue meter. It includes a battery-operated proving unit for pre-and post-measurement verification and offers adaptors for Bowthorpe Rod connections. A Repeater Station can replicate readings at ground level, and the carry case provides space for additional accessories. Available in the UK and internationally, it ensures reliable performance with its detailed construction and comprehensive components.
The LLT-3.3kV 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-3.3kV 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 3.3kV, the measuring range can extend as high as 5kV, with a resistor chain of 22.5MΩ. 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.
