What are the various fault finding techniques?
Here are six key points to consider:
- Collect the Evidence. All the evidence collected must be relevant to the problem in hand.
- Analyse the Evidence.
- Locate the Fault.
- Determination and Removal of the Cause.
- Rectification of the Fault.
- Check the System.
What is fault in device or program?
A software fault, also known as a “crash” or “abend,” is when the program directs the computer to go outside of its restricted memory boundary. A hardware fault is a failure in one of the circuits. See fault detection, fault isolation and fault management.
How do you deal with intermittent fault conditions?
Some techniques to resolve intermittent faults are: Automatic logging of relevant parameters over a long enough time for the fault to manifest can help; parameter values at the time of the fault may identify the cause so that appropriate remedial action can be taken.
What is the purpose of fault finding?
If repair is done as a business, fault finding is a main factor of calculation of costs. The time consumed for it is a very big portion of the overall time spend for the repair. A quick location of faults is therefore reducing the costs and gives so the professionalist a big advantage in competition.
How do you diagnose an electrical fault?
How to identify electrical faults
- Switch off the main power at the consumer unit/fuse box.
- Or switch off the breaker and lock it if you can.
- Attach a note to the unit to advise you are working on the circuit.
- Check the circuit is dead with a socket tester or voltage tester/meter for lighting circuits.
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 is a fault condition?
A fault condition occurs when one or more electrical conductors short to each other or to ground. A fault current is usually several times larger in magnitude than the current which normally flows through the circuit in a non-fault condition.
What is an intermittent short?
Intermittent Shorts When some force (bending, flexing, vibration, aging, etc.) causes the conductors to be isolated by an air-gap, the wires come into physical contact with each other, and a short-circuit occurs.
What is intermittent ground fault?
An intermittent or arcing ground fault can result in a buildup of voltage on the system, stressing and deteriorating insulation and resulting in voltages as much as 6 times higher than the nominal system voltage. Another benefit of a grounded system is the ease of locating a ground fault.
How important is fault finding for reliable cabling connections?
Faults can occur on all types of cable, at any age or voltage. If found early enough, such an issue can be repaired, preventing possible cable failure in the future.
How do you deal with intermittent conditions?
How do you track a ground fault?
To locate a ground fault, look for continuity to ground on each circuit. This new analog ohmmeter will show infinite ohms when the conductor is not exposed to an earth ground. If the insulation is compromised and/or the copper is directly connected to ground the ohmmeter will indicate 0 ohms.
What is the difference between fault tolerance and high availability?
The difference between fault tolerance and high availability, is this: A fault tolerant environment has no service interruption but a significantly higher cost, while a highly available environment has a minimal service interruption.
What is fault tolerance techniques?
Fault-tolerance is the process of working of a system in a proper way in spite of the occurrence of the failures in the system. hence, systems are designed in such a way that in case of error availability and failure, system does the work properly and given correct result.
