Why this step matters
Begin with a precise boundary and decision.
This step turns a broad concern into a defined technical question. It establishes what is included, what is excluded, which operating conditions matter, and how the result will be used.
Confirm the people, records, access, safety limits, asset context, and decision criteria before work begins.
Applied to Partial-discharge assessment
- Technical focus: Corona, surface discharge, and internal discharge indicators
- Where it applies: Medium-voltage switchgear
- Expected evidence: Screening results by asset
- Working principle: Partial discharge is a risk indicator whose meaning depends on type, location, magnitude, trend, and asset consequence.
What happens in practice
- 01Prepare the context
Confirm the asset, people, records, operating state, and boundaries needed to address corona, surface discharge, and internal discharge indicators.
- 02Make the work traceable
Confirm the people, records, access, safety limits, asset context, and decision criteria before work begins.
- 03Confirm the handoff
Check that the result can support screening results by asset and that unresolved uncertainty is visible.
A sample of how this step may unfold
A maintenance team requests focused technical support after an exception appears during an inspection, route, or operating review. Before any work begins, the team identifies “Corona, surface discharge, and internal discharge indicators” as the immediate focus. It agrees that the step should produce screening results by asset, and it records what is outside the present scope. The example closes with the principle that partial discharge is a risk indicator whose meaning depends on type, location, magnitude, trend, and asset consequence.
This is an educational example, not a description of a specific client engagement or a guaranteed result.Evidence to expect
What should be visible before moving on.
- A written scope boundary
- The operating decision to support
- Known asset and process context
- Access, safety, and timing constraints
Common mistake
What weakens this step.
Starting with a favorite instrument, test, course, or platform before defining the decision it must support.
What good looks like
- Everyone can state the same technical question
- The boundary and exclusions are visible
- The expected output will support a real decision
Where this step ends
A clear record, a clear limit, and a clear next move.
A good closeout leaves the next person with a practical explanation of what was done, what the evidence supports, what remains uncertain, and what should happen next. For this capability, the working principle remains: Partial discharge is a risk indicator whose meaning depends on type, location, magnitude, trend, and asset consequence.
