Fault tree analysis (FTA) is a top-down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event

The analysis of these types of faults is often simplified by using methods such as symmetrical components. Common types of asymmetric fault, and their causes: line-to-line fault - a short circuit between lines, caused by ionization of air, or when lines come into physical contact, for example due to a broken insulator. In transmission line faults, roughly 5% - 10% are asymmetric line-to

Common Cause Failures (CCFs) are single faults that result in the failure of multiple components. Typical examples include impact, vibration, temperature, contaminants, miscalibration, improper maintenance, etc. There are different methods to address CCFs, both qualitative and quantitative. In this article, we discuss the β factor method and provide an example of an application of this method

Faults may lead to fire breakout that consequently results into loss of property, loss of life and destruction of a power system network. Faults also leads to cut of supply in areas beyond the fault point in a transmission and distribution network leading to power blackouts; this

Study of transformers, the faults that most commonly occur, the causes of these faults and their impact is conducted and discussed in this paper. The transformers that were studied were step-down transformers (11kv-220v) used by WAPDA in distribution sectors. Data about the transformer failure for the last 5 years was collected from PESCO for two locations of Peshawar district. The first

W hether related to motors, pumps or any other types of industrial machinery, shaft failure analysis is frequently misunderstood, often being perceived as difficult and expensive. For most machine shafts, however, analysis should be relatively straightforward. That's because the failure typically provides strong clues to the type and magnitude of forces on the shaft and the direction they

The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain. As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particle's weight and the

Common Cause Failures DEFINITION • Subset of Dependent Failures in which two or more component fault states exist at the same time, or within a short time interval, as a result of a shared cause. • The shared cause is not another component state because such cascading of component states, due to functional couplings, are already usually

Bolted line-to-line faults, Figure 1(b), are more common than three phase faults and have fault currents that are approximately 87% of the three phase bolted fault current. This type of fault is not balanced within the three phases and its fault current is seldom calculated for equipment ratings because it does not provide the maximum fault current magnitude. The line-to-line current can be

Water not only rusts iron surfaces, but it can also increase the oil's oxidation rate, leading to an acidic environment within the component. Acids can also be formed as byproducts of reactions between certain additives in the oil and water

From the short-circuit analysis point of view, three-phase fault lends itself to single-phase analysis, because the fault is balanced all three and asks for phases, presuming a balanced threephase electrical - system.

Most of these faults show characteristics that are identifiable with vibration analysis. Others may show better through oil analysis or thermography. Misalignment Misalignment is universally recognised as the leading contributor to machinery failure. For the same level of vibration it is much more serious than unbalance for its effect in reducing bearing life, largely because of the parasitic
