This is an advanced instrument capable of identifying a wide range of cable faults. The Megger TDR1000/3 uses a technique called Pulse Echo (also known as Time Domain Reflectometry or TDR). A pulse is launched into a cable from one end. This can be on either a pair of conductors, or a conductor and the screen. The cable’s construction will determine its characteristic impedance and the velocity a pulse travels down the cable.

The pulse velocity is normally described as a fraction of the speed of light and is called the Velocity Factor. By measuring the time between the transmitted pulse and the reception of the reflected pulse, and multiplying this by the speed of light and the velocity factor, the actual distance to the reflection point can be established.

The Megger TDR1000/3 can be used on any cable consisting of at least two separate conductive elements, one of which may be the armouring or screen of the cable. It has internal matching networks to allow testing of 25Ω, 50Ω, 75Ω and 100Ω cables. (These typically correspond to power, coaxial data and data/telecoms cable).

The TDR 1000/3 has a minimum resolution of 0.1 m and a 5 km maximum range depending on velocity factor selected and cable type. Four output impedances are available (25, 50, 75, and 100 Ω) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.
