What are the steps to fault finding?
What are the steps to fault finding?
Here are six key points to consider:
- Collect the Evidence. All the evidence collected must be relevant to the problem at hand.
- Analyse the Evidence.
- Locate the Fault.
- Determination and Removal of the Cause.
- Rectification of the Fault.
- Check the System.
What are the five steps to fault finding?
- Step 1 – Observe. Most faults provide obvious clues as to their cause.
- Step 2 – Define Problem Area.
- Step 3 – Identify Possible Causes.
- Step 4 – Determine Most Probable Cause.
- Step 5 – Test and Repair.
How do you find the fault in an electrical circuit?
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 the 6 point fault finding technique?
finding method The six point fault finding technique has six steps: 1. Test the system, i.e. make measurements or collect other evidence, 2. Analyse the reading, 3. Locate fault based on analysis, 4.
What is the first step to take when there is an electrical fault?
When you have an electrical breakdown at home the first thing to do is to check that the switches on the circuit breaker panel are all raised, including the general switch and the differential. If everything is correct, the next step is to lower the centre switch and wait five to ten seconds before raising it again.
What is emergent problem sequence?
Emergent problem sequence is related to identifying if anything has changed recently. getting the fault found as quickly as possible. dealing with an emergency. identifying a fault that as occurred before.
What are the 4 electrical faults?
Types of Faults in Electrical Power Systems
- Open Circuit Faults. Causes. Effects.
- Short Circuit Faults. Causes. Effects.
- Symmetrical and Unsymmetrical Faults. Symmetrical Faults. Unsymmetrical Faults.
What are the three classifications of electrical problems?
Unsymmetrical faults There are mainly three types namely line to ground (L-G), line to line (L-L) and double line to ground (LL-G) faults.
When troubleshooting which measurement should you make first?
You should always test the meter before using it to troubleshoot.
- For a voltmeter, test the meter on a known voltage source before using. Your meter should read the correct voltage.
- For an ohmmeter, touch the meter leads together. The display should read 0 ohms, or very close to 0.
