What changed: Service scope, report outputs, official sources, pre-proposal information and technical transparency notes were reviewed for the current period.
Electrical Periodic Inspection and Examination Summary
- Select inspection categories from the actual electrical inventory and identify exclusions in writing.
- Confirm the applicable period, methods, criteria and inspector conditions for each selected category.
- Keep visual findings, measurements and functional responses distinct, using suitable equipment for the method.
- Plan access, critical loads, outages and restoration with the operator, retaining tests that could not be performed.
- Track findings with reasons; define corrective work and any verification after repair separately.
Technical contact and professional information
Electrical Periodic Inspection and Examination Scope
Select the inspection scope first
Use this page to choose among electrical periodic inspection services. Panel or building quantities alone do not define the examination: identify installations, devices and connections. Mechanical work-equipment inspection is outside this electrical service. A facility need not include every category below; the proposal identifies the selected inventory.
| Category | What the plan defines | What is not automatically included |
|---|---|---|
| Installations and panels | Actual circuits, protection and selected examination/measurements | Verification of every concealed part or acceptance of new work |
| Grounding and lightning protection | The connections, methods and criteria of systems with different functions | Complete protection or step/touch safety from one resistance value |
| Transformers and MV equipment | Installed model, access, operating conditions and selected checks | Every type test, oil analysis or servicing/repair package |
| Generators, UPS and batteries | Electrical/functional scope, transfer and load conditions | Full capacity/autonomy testing or every mechanical service |
| Fire detection and warning | Selected points, scenarios and interfaces under controlled conditions | The entire suppression system or all points from a single trial |
Examination, measurement and function provide different evidence
A visual finding describes accessible condition; a measurement concerns an identified path under test conditions; a functional trial records a selected device or scenario response. They are different activities. PE continuity, electrode, loop, RCD and insulation methods are not substitutes. Do not select a generic test voltage or connection without knowing the equipment and manufacturer limits.
Information required before a proposal
Share site use, voltage levels, equipment/point lists, single-lines and drawings, previous reports, open findings and later modifications. Explain the intended use of the report. These inputs start scope definition; quantities or floor area alone do not establish duration or feasibility of every test.
Determine periods and criteria by category
Confirm current applicable provisions, standards and manufacturer conditions for each item and record the period and its basis. One visit does not create one calendar for all equipment. Risk and operating information may identify additional or earlier examination needs; they are not an automatic reason to extend a binding maximum period. Routine servicing and post-event or post-change investigation remain distinct from formal periodic inspection.
Inspector eligibility and instruments
Before work, confirm the professional eligibility, registration and required contract for the category, voltage and report purpose. Check EKİPNET and İSG-KATİP conditions where applicable. A title, registration number or general accreditation claim alone does not establish authorization and acceptance for every category. Assess instrument suitability, traceability and relevant calibration information against the selected method.
A practicable site test plan
Agree access, supply sources, critical loads and operations that may interrupt service with the operator. If authorized work and restoration conditions cannot be established, do not record the activity as performed. Retain points, methods and conditions; sampling or limited access does not give a positive result for the whole inventory. This overview supplies no switching, live-work or universal connection procedure.
Report content and intended use
Connect actual equipment/point identities, date, conditions, method, criteria, instruments, results and findings. State unperformed tests, excluded areas and needs for further examination. Explain finding priorities using the evidence. Use in an authority, insurance or acceptance process depends on that process’s conditions; a signature alone does not guarantee acceptance.
From findings to correction and verification
Inspection does not establish that maintenance or repairs were completed. Assign corrective responsibilities, planning, records and any reverification separately. Later machinery, circuit, supply or protection changes are not automatically covered by an earlier report. One examination cannot exclude every concealed defect or future fault.
Discuss the service that fits the need
Share the inventory and latest report to define included checks, separate work and deliverables. The installation, grounding, lightning-protection, transformer, generator, battery and fire-detection pages support category-specific discussion. Design, operation responsibility and physical implementation remain separate services.
Reporting, Inspection and Proposal Preparation
Sample Inspection Table
This table summarizes which headings are evaluated on site and which outputs may appear in the report.
| Inspected area | Checked criterion | Report output |
|---|---|---|
| Site and equipment condition | Existing equipment structure, access conditions, visible risks and operating conditions | Site inspection note and prioritized findings list |
| Document and project conformity | Single-line diagram, current project, labeling, reports and conformity with site implementation | Document conformity assessment and missing record list |
| Safety and operational risk | Life safety, equipment safety, energy continuity and maintenance access risk headings | Risk classification and corrective action recommendations |
| Measurement, test or inspection need | Measurement, test, visual inspection and technical review items required by the service scope | Measurement/test plan or inspection scope note |
| Reporting and follow-up | Nonconformity priority, follow-up date, responsibility allocation and next steps | Photo-supported report, action list and follow-up recommendation |
Selected Inspection Scope and Additional Work
The proposal identifies which electrical systems and inspections are included. Grounding measurement is part of the service when grounding inspection is included in that inventory.
| Work item | Relationship to the service | Scope decision |
|---|---|---|
| Agreed electrical inspections and measurements | The selected installation, grounding and other equipment inspections follow the agreed inventory. | Findings and measurement results are recorded in the applicable inspection reports. |
| Equipment or tests outside the selected inventory | Additional systems require their own inspection methods and site time. | Additional scope and reporting are agreed before inspection. |
| Repair, replacement and physical remediation | An inspection identifies a defect; corrective work may require materials and installation. | Remediation is planned separately and does not replace the inspection report. |

Frequently Asked Questions
Are periodic inspection and periodic examination the same thing?
The two expressions describe scheduled examination and assessment here; their names do not create different statutory levels. The selected category, method, eligibility, period and report determine the actual scope.
Which equipment is included in periodic inspection?
Select installation, grounding, lightning protection, transformer/MV, generator, UPS-battery and fire-detection items from actual needs and the proposal. Each retains its own methods and responsibility boundaries rather than forming an automatic all-inclusive package.
How often should periodic inspection be performed?
Confirm the applicable current provisions, criteria and manufacturer conditions for the actual category and record the period and basis. Additional checks and maintenance calendars are separate. This page sets no universal annual interval for every item.
Why is periodic inspection important?
Examination and selected tests support documenting, prioritizing and following findings. They do not guarantee discovery of every concealed or future defect. Corrective work and verification are separately planned.
Is a report delivered after periodic inspection?
Report the checks actually performed with scope, methods/criteria, conditions, results, findings and limitations. Untested or excluded parts remain explicit. Delivering the report does not mean repairs were implemented.
Is periodic inspection necessary only for large facilities?
Need depends on use, equipment categories and applicable conditions as well as size. A small site can require a defined inspection scope. Do not presume the same list or procedure for every building.
Who can perform electrical periodic inspection?
Choose a person meeting the conditions applicable to the equipment category, voltage and report purpose, including required registration and contract. An engineering title or EKİPNET number alone does not cover every item or guarantee report acceptance. Methods and instrument suitability need separate assessment.
What does an electrical periodic inspection report include?
Record identities, date, inventory, methods/criteria, instruments, conditions, results, findings, limitations and follow-up. Keep corrective implementation and reverification status separate. Acceptance depends on the receiving process’s document and eligibility requirements.
