What are the fault finding techniques?
What are the six key steps to approach electrical fault finding?
- 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.
How do you find the fault in an electrical circuit?
7 Steps to Electrical Fault Finding
- Turn all circuit breakers off.
- Turn the main safety switch on.
- Turn each circuit breaker back on.
- Identify the faulty circuit.
- Turn all switches off again.
- Turn the electricity back on.
- Call a fault finding electrician.

What is fault finding Electrical?
Electrical Fault Finding An initial inspection of fittings and fixtures will be carried out to check for loose connections signs of burning or dampness. If no obvious faults are detected we will proceed to carrying out an in-depth electrical fault finding test using calibrated electrical fault finding test equipment.
What is 6 point fault finding?
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. Repair the fault, 6. Retest the system.
What are the types of electrical 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. Line to ground fault (L-G) is most common fault and 65-70 percent of faults are of this type.
What is electrical fault finding?
Fault finding means the testing of the operation of electrical equipment to determine if that electrical equipment is safe and working correctly as defined in the Victorian Electricity Safety (Registration and Licensing) Regulations 2010.
What is a fault in electrical systems?
An event occurring on an electric system such as a short circuit, a broken wire, or an intermittent connection.
