Sample questions
01What is the first step in systematic fault finding?
- AReplace the most likely faulty component immediately
- BGather information about the symptoms and history
- CIsolate and dismantle the affected equipment
- DCarry out an insulation resistance test
Why: Start by gathering information: what happened, when, any changes made, symptoms observed, to understand the problem.
02What is the logical six-point fault finding approach?
- AInspect, test, record, report, repair, re-test
- BGather info, analyse, identify possible causes, test hypothesis, rectify, verify
- CIsolate, prove dead, dismantle, replace, reassemble, energise
- DIdentify, evaluate, control, record, review, communicate
Why: Six-point approach: gather information, analyse symptoms, identify probable causes, test to locate fault, rectify, verify operation.
03What is the 'half-split' method in fault finding?
- AComparing readings from two identical installations
- BDisconnecting half the circuits to reduce the test current
- CTesting at the midpoint to determine which half contains the fault
- DSplitting the load equally across two circuits
Why: Half-split: test at the midpoint of a circuit to determine which half contains the fault, then repeat in the faulty half.
