How to Determine Periodic Control Frequency?
📐 Regulations and Standards
In Annex III of the Regulation on Health and Safety Conditions in the Use of Work Equipment, maximum periodic inspection periods for some work equipment are given in a table. These maximum periods cannot be exceeded for the equipment listed in the tables; If the risk is high, the period can be shortened further.📝 Scope of Articles 1.4 and 1.10
• If the period is not specified in the table or standard; The period recommended by the manufacturer is taken into account.• If the manufacturer did not give a time period; Risk assessment is made according to workplace environmental conditions, frequency of use, age of the equipment and previous inspection results.
• In no case can the periodic inspection period exceed the maximum periods specified in the relevant tables.
🔎 General Approach for Electrical Equipment
- In practice, it is mostly used for internal electrical installations, grounding installations and lightning rod systems. maximum 1 year period is taken into account.
- In transformer, MV cubicles, generator and UPS/battery systems; By evaluating both the relevant standards and the operating conditions of the equipment, it is generally annual periodic inspection recommended.
- In facilities with high fire and explosion risk such as chemical, textile, plastic and logistics warehouses; These periods may be shortened further according to the results of the risk assessment.
Our Periodic Inspection Process
1️⃣ Preliminary Preparation and Document Review
• Review of existing electrical projects, single line diagrams, previous periodic inspection reports and corrective action records• Reviewing the hazard class of the business, production processes and critical lines
2️⃣ Field Discovery and Risk Based Planning
• On-site inspection of transformer, MV cubicles, main distribution panels, secondary panels, battery/generator rooms, grounding points and lightning rod installations• If appropriate, combining more than one periodic inspection issue (e.g. internal electrical installation + grounding + lightning rod) on the same day
3️⃣ Measurements and Tests
• Grounding measurements, loop impedance, leakage current and insulation tests• Lightning rod continuity and measurement tests
• Electrical tests and function checks for transformers, generators, UPS/batteries and panels
4️⃣ Evaluation and Classification
• Comparison of results with relevant legislation and standards• Separation of appropriate, conditionally appropriate and inappropriate findings
• Determination of urgent, short-term and medium-term corrective action suggestions
5️⃣ Reporting and Tracking
• Preparation of periodic inspection and inspection reports signed by the engineer• Sharing the nonconformity list with the business
• Planning recommendations for the next periodic inspection period
Who Can Perform Periodic Control?
• Persons authorized in accordance with the Regulation on Health and Safety Conditions in the Use of Work Equipment
• Engineers, technicians, senior technicians or technical teachers (in relevant fields) who are registered with Fikirnet.
• Technical knowledge and field experience in electrical installation, grounding, lightning rod, transformer and generator.
• Valid calibration certificates for the measurement and testing devices used
What Documents Do We Deliver at the End of Periodic Inspection?
📋 Grounding and Lightning Rod Measurement Reports: Measurement result tables, limit value evaluations and non-conformities
📋 Transformer, MV Cells and Generator Periodic Control Reports: Tests performed, function checks and recommended maintenance/improvements

Frequently Asked Questions
What is the difference between periodic checkup and periodic inspection?
Periodic inspection; It refers to the measurement, testing and visual inspection of work equipment such as electrical installation, grounding, lightning rod, transformer and generator at regular intervals. Periodic inspection is; It defines the general process that covers all of these controls. In practice, the two concepts are used together and handled within the same legislation.
Which equipment is subject to periodic inspection?
Within the scope of the Regulation on Health and Safety Conditions in the Use of Work Equipment; Internal electrical installations, grounding installations, lightning rod and lightning protection systems, transformer and MV cubicles, generator, UPS/battery groups and fire detection-warning systems are subject to periodic inspection. Compliance of these equipment with relevant legislation and standards should be checked at regular intervals.
How often should periodic inspections be performed?
The period is determined by taking into account the relevant standards, the maximum periods in Annex III table, manufacturer recommendations and risk assessment. For most electrical installations, grounding and lightning rod systems, the maximum periodic inspection period is generally considered to be 1 year in practice. This period is further shortened in high-risk facilities or under heavy working conditions.
Who can perform periodic inspections?
Periodic inspections; It should be carried out by engineers, technicians, senior technicians and technical teachers who are authorized in accordance with the Regulation on Health and Safety Conditions in the Use of Work Equipment, registered in the Equipnet system and have technical knowledge on the subject. It is mandatory that the test devices used are calibrated and the reports are prepared in accordance with the legislation.
Are your periodic inspection reports valid in official inspections?
Yes. Periodic inspection and periodic inspection reports containing reference to legislation and relevant standards, prepared by Equipment registered personnel and approved by the engineer; It is a valid and strong document for the Ministry of Labor, OIZ administration, fire department and insurance inspections.
What is the risk of not having periodic inspection-ups?
In electrical installations and equipment that are not regularly checked; Leakage current, insufficient grounding, inoperative lightning rod, overheated panels, faulty transformer or generator protections may not be noticed. This may lead to electric shock, fire, loss of production and serious material damage; During official inspections, it may cause administrative fines, work stoppages and problems in insurance processes.
