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

The Metrohm Live Line Tester Kits (LLT3.3) have been specifically designed to perform measurements for both live voltage testing and phasing on overhead lines, in substations and within switchgear compartments. A Live Line Tester Metrohm LLT assemby for use on switchgear.is a device that draws current from the source under test. This current flows through a resistive chain to earth via an earth lead. The current flow is monitored and displayed on a moving coil meter which is graduated in kV.

When checking phase relationships a Phasing Rod is used in conjunction with a Live Line Tester. Currents from two sources are combined and displayed on the meter on the Tester. In-phase voltages will read twice the phase to earth voltage and out-of-phase voltages will read the phase to earth voltage only.

Near the contact end of the Tester and Phasing Rods there is a red band which is the limit mark. By definition this mark indicates the physical limit to which these items may be inserted between live components or may touch them.

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. Made from high quality fibreglass rods and polycarbonate mouldings the equipment is suitable for both indoor and outdoor use – including wet conditions.

SAFETY RULES:

Only personnel who are fully trained in the use of Live Line Testers should use this equipment.
Ensure the tester and accessories are clean, free from cracks or deep scores, and are properly secured together.
Make certain that the Tester is properly rated for the voltage of the system under test.
Test the operation of the assembled Tester complete with accessories before and after each test.
Do not allow a live high voltage conductor to come in contact with the detector at point below the limit mark.
The Tester must never be used without a handle or without insulating rods incorporating a handle.
Safe working distances must always be observed.
Always connect the earth lead clip to a secure earthing point before performing a test.
