What is a fault condition?
A fault condition occurs when one or more electrical conductors short to each other or to ground.
The fault types are phase to ground, double phase to ground, three phase to ground, phase to phase and three phase..
What is a good example of fault tolerance?
A twin-engine airplane is a fault tolerant system – if one engine fails, the other one kicks in, allowing the plane to continue flying. Conversely, a car with a spare tire is highly available. A flat tire will cause the car to stop, but downtime is minimal because the tire can be easily replaced.
What can cause an earth fault?
An ‘Earth fault’ (also known as a ground fault, isolation fault or leakage current) is a form of short-circuit fault where the active electricity path is accidentally connected to the ground through a fault in the electrical system.
How do you find a short circuit fault?
The first thing you’ll need to do to find a short circuit is to look for physical signs. This may include visible burns or metal on wires, burning smells, or flickering lights. Once you’ve identified a potential short, use your multimeter to confirm the voltage by setting it to resistance or continuity setting.
How do you detect faults?
The most common technique for detecting faults is the time-frequency analysis technique. For a rotating machine, the rotational speed of the machine (often known as the RPM), is not a constant, especially not during the start-up and shutdown stages of the machine.
What is the difference between fault and defect?
A Defect is a variance between expected and actual results. An Error that the tester finds is known as Defect. … The defect is also known as Fault.
