Periodic Inspection and Periodic Examination

Periodic inspection service covers the measurement, testing, technical assessment and reporting of electrical installations, grounding, lightning protection, transformers, generators, UPS-battery groups and fire detection systems at defined intervals. The purpose is not only to prepare documentation, but to identify electrical fire, electric shock, unplanned outage and equipment damage risks at an early stage. For related context, see High Voltage Installations Engineering and Consultancy.

This service is a fundamental inspection process for industrial facilities, production areas, warehouses, commercial buildings, hospitals, schools, offices and multi-purpose buildings with electrical infrastructure in terms of occupational safety and business continuity. For related context, see High Voltage Operation Responsibility Service.

Periodic inspection means evaluating facilities, installations and work equipment at defined intervals through measurement, testing, visual examination and document review. Periodic examination is the broader term covering the full process and its reporting. For related context, see Transformer Substation Design.

In practice, the two expressions are often used together. What matters is that inspections are performed by authorized persons, measurement results are recorded, nonconformities are classified and the process is documented with a technical report. For related context, see Short-Circuit Analysis and Relay Selectivity Studies Service.

Periodic inspection work is carried out by considering Law No. 6331 on Occupational Health and Safety, Annex III of the Regulation on Health and Safety Conditions in the Use of Work Equipment, the Electrical Internal Installations Regulation, the Electrical High Current Installations Regulation, the Electrical Grounding Installations Regulation and the relevant TS EN, TS HD and IEC standards.

Unless otherwise specified in the relevant standards, an annual inspection approach is commonly used for electrical installations, grounding installations, lightning protection installations, batteries, transformers and similar electrically related installations. If the risk is high, the inspection interval should be shortened.

This page covers periodic inspection topics related to electricity. Mechanical equipment, lifting equipment and pressure vessels are outside the scope of this service.

The inspection scope consists of electrical installations and distribution panels, grounding installations, equipotential bonding, lightning protection systems, transformers and medium-voltage equipment, generators and transfer infrastructure, UPS-battery groups, battery rooms and electrical checks of fire detection and warning systems.

Depending on the needs of the business, these inspections can be planned separately or as an integrated service within a single site organization.

Inspection criteria are determined not only according to general regulatory clauses, but by evaluating equipment technical characteristics, manufacturer recommendations, operating intensity, environmental conditions, maintenance history, previous periodic inspection reports and the facility risk level together.

Facilities with heavy operating conditions, continuously energized systems, high load levels or fire risk may require more detailed measurement and a more frequent inspection approach.

The process starts with reviewing existing projects, single-line diagrams, maintenance records, previous reports and equipment information. Then panel rooms, transformer areas, generator sections, grounding points, lightning protection components and fire detection infrastructure are evaluated on site.

During measurement and testing, grounding measurements, insulation tests, continuity checks, residual current checks, thermal camera inspections and protection system assessments are performed. Findings are interpreted together with technical requirements and site conditions and converted into a report.

Periodic inspections of electrical installations and electrically related work equipment must be performed by engineers or authorized technical personnel who are competent in the relevant field, registered in EKİPNET and using calibrated measurement devices.

A proper periodic inspection is not only about writing measurement results. Field risks must be interpreted, nonconformities must be prioritized and corrective action recommendations that the business can implement must be provided.

After the inspection is completed, the summary of examinations, measurements and tests, measurement results, nonconformity list, risk priorities, corrective action recommendations and general technical assessment are delivered to the business as a report.

These reports are core technical records for official audits, internal occupational safety follow-up, insurance processes, maintenance planning and future periodic inspection periods.

Periodic inspection service is suitable for all businesses with electrical infrastructure that want this infrastructure to operate safely. From small businesses to large factories in organized industrial zones, a regular inspection approach is important in every building.

Industrial facilities, production areas, logistics warehouses, shopping centers, hospitals, educational institutions, public buildings, offices, business centers and multi-storey buildings are among the main structures that may need this service.

Professional periodic inspection enables early detection of risks, strengthens electrical and fire safety, reduces unplanned outages, creates documented technical follow-up and helps the business prepare for audits more effectively.

A standard-compliant periodic inspection carried out with an engineering perspective is not only a legal obligation; it is a fundamental measure for facility safety, employee safety and sustainable operation.
