Intro to fault location in low voltage networks
Fault occurrences in medium voltage networks are usually covered by redundancy in the system which, with appropriate switching, usually ensures a relatively uninterrupted continuation of the supply for the customer. A lengthy wait until the fault can be corrected only results in the increased risk of a second failure in this area, creating a customer outage that cannot be restored by switching.

Examples of fault location
In branched low voltage networks, low-resistance faults, interruptions and large changes in impedance can only be located by comparing fault-free and defective cores.

Pre-location based on impulse reflection methods
The use of T-branches in low voltage networks makes the evaluation of TDR traces considerably more difficult. Only through comparative measurements of fault-free and defective wires can possible results be achieved. The test pulses of the Teleflex are partially reflected at the T-joint with a negative algebraic sign, while test pulses that continue are simultaneously reduced in amplitude. The amount of reflection depends on the impedance in the main line and the continuing line.

Methods of fault location in low voltage networks
There are multiple ways to find a cable fault in a low voltage network, but no one method works for all situations. It’s only by knowing the pros and cons of each method that you can determine the most effective one to use in any given scenario and pinpoint the fault in as little time as possible.

BITE field calibration verification
Each Megger BITE product can measure internal cell impedance, inter-cell connection resistance and dc voltage of cells and jars. But only BITEs can be checked in the field for calibration validity to ensure quality of the data generated. This is because only Megger’s BITE instruments measure current simultaneously to potential.

UHF PD Diagnosis at high voltage cable terminations
High voltage terminations are essential components in high voltage cable systems. Great reliability is provided by high manufacturing quality and company type testing. However, onsite installations represent a considerable uncertainty for successful service of the system. UHF PD Diagnosis has proven to be a valuable and effective method for measuring high voltage assets because this online measurement is performed at frequencies which are not affected by environmental noise.
