Fortunately, two analytical techniques are now available that can significantly increase the effectiveness of the fault localization process.

Based on the data analysis, fault localization by SSM should isolate the short in the die, bond wires or package substrate.

Obtaining the SSM data from scanning advanced wire-bond packages is only half the task; fault localization is still necessary.

There exist fault localization methods to find the bug location as these model checking tools return a long counter example trace and it is hard to find the exact faulty location.

Impedance changes at the fault location make measuring more difficult.

In this situation the virtual earth point will move to the shunt fault location.

In very simple wiring systems, the fault location is often found through inspection of the wires.

The measures necessary for determining fault locations can be subdivided into individual steps.

These methods of cable fault location quickly became established in Western Europe as well.

Fault location is done by listening for the sound of the discharge at the fault.

The resulting current map can then be compared to a circuit diagram to determine the fault location.

Cable testing is therefore usually performed first in cable fault location.

The resulting potential rise can cause hazardous voltage, many hundreds of yards (metres) away from the actual fault location.

While this test contributes to damage at the cable site, it is practical because the faulted location would have to be re-insulated when found in any case.

'Fault location and repair takes much longer with underground cables, and this could result in customers being without supply for longer periods.'

In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.

The spread spectrum time domain reflectometry has the advantage of precisely locating the fault location within thousands of miles of aviation wiring.

"Spread Spectrum Sensors for Critical Fault Location on Live Wire Networks".

Cable fault location is the process of locating periodic faults, such as insulation faults in underground cables, and is an application of electrical measurement systems.

During the first years of operation Kelman developed a number of award winning products, including a low voltage autorecloser, a circuit breaker analyser and fault location equipment.

Since a number of experts in the field of pulse technology were available, the decision was made to focus on cable testing equipment and implement ideas for a fault location device.

Time domain reflectometry, specifically spread spectrum time domain reflectometry is used for aviation wiring for both preventative maintenance and intermittent fault location.

In July 2012 Megger acquired SebaKMT specialising in power cable fault location and testing, and pipe leakage detection.

Megger also won in earlier editions, for instance in 2007 these were: multifunction tester MFT 1553 and portable cable fault location PFL40.

If only reflection magnitudes are desired, however, and exact fault locations are not required, VSWR bridges perform a similar but lesser function for RF cables.

The second fault location technique will be taken somewhat out of turn, as it was used to characterize this failure after the SQUID analysis, as an evaluation sample for an equipment vendor.

In simple wiring systems visual inspection can lead to finding the fault location, but in complex wiring systems, for instance aircraft wiring, devices such as a time-domain reflectometer are helpful, even on live wires.

Fault location techniques can be broadly divided into terminal methods, which use voltages and currents measured at the ends of the cable, and tracer methods, which require inspection along the length of the cable.

Marconi simulation Ltd have installed the equipment to enable reactor staff to experience fault recognition and rectification in situations that would not normally happen in everyday operations.
