Concours ENSOA Spécialiste key terms

The defined part of an installation being analyzed, which helps identify relevant inputs, outputs, interfaces and assumptions before diagnosing a fault.

An observed departure from intended operation, distinguished from assuming that a particular component has already been proven to cause the problem.

Information from observations or appropriate tests that supports fault analysis when interpreted under the actual operating conditions and documentation.

The equipment-specific reference describing relevant characteristics, procedures and limits, whose version and applicability should be checked before use.

The permitted variation for a specified characteristic under defined conditions, distinguished from an unrestricted allowance for any inaccurate result.

A documented comparison relating instrument indications to reference values under specified conditions, rather than automatically repairing every instrument defect.

The quantified dispersion associated with a measurement result, which must be distinguished from an unnoticed mistake or an assumed exact value.

An arrangement connecting components along one path, whose voltage, current and resistance behavior depends on the actual circuit model.

An arrangement connecting components across common nodes, requiring analysis of branch currents and equivalent behavior under the stated conditions.

The ratio of real power to apparent power in an AC system, interpreted with the applicable waveform and operating assumptions.

The combined vector obtained by accounting for the magnitudes and directions of contributing quantities, rather than adding magnitudes in every situation.

A change between equivalent measurement units using the correct scale relationship while preserving the physical quantity and dimensional consistency.

Energy remaining in a system that may present a hazard after a normal stop, requiring the appropriate authorized control and verification.

Separation from relevant energy or other sources through the actual authorized procedure, distinguished from merely assuming a stop control removes all hazards.

The authorized restoration of equipment to use after required work and checks, supported by evidence rather than an incomplete inspection signature.

The controlled tracking of tools and other items to prevent loss, unauthorized access and foreign-object hazards during maintenance work.

A structured representation connecting a defined failure event with possible contributing causes, whose branches require evidence rather than automatic acceptance.

Planned work intended to reduce failure risk according to the applicable equipment requirements, distinguished from every possible diagnostic or corrective activity.

The management of an item approved arrangement, versions and changes so that documentation and actual equipment remain consistent.

Communication of equipment condition, completed work, outstanding hazards and relevant records to the next responsible person or team.
