What is generator periodic inspection in Bursa
Generator periodic inspection is the process of examining and testing generator sets and generator installations used as a main or backup energy source in a facility at defined intervals according to legislation and the relevant TS / TS EN standards. In practice, this service may be called generator periodic examination, generator installation periodic inspection, generator periodic tests, generator periodic inspection report, generator periodic inspection form or generator periodic examination report. Their common purpose is to verify that the generator system that will operate during a power outage works safely, adequately and in accordance with the generator criteria for work equipment periodic inspection. For related context, see Bursa Battery Periodic Inspection.
Generator inspection and maintenance are different
Generator periodic inspection should not be confused with conventional generator maintenance services. Periodic maintenance covers operating and service activities mostly based on manufacturer recommendations, such as oil changes, filter changes, cleaning, adjustment and calibration. Periodic inspection and periodic examination are independent test and inspection activities required by the Regulation on Health and Safety Conditions in the Use of Work Equipment, and an official generator periodic inspection report is issued at the end. Generator periodic maintenance, including daily, weekly, monthly, quarterly, six-monthly and annual steps, extends generator life and reduces faults, but it does not fulfill the statutory periodic inspection obligation by itself. For related context, see Bursa Transformer Periodic Inspection and Testing.
Legal basis and inspection interval
The legal basis for generator periodic examination is Law No. 6331 on Occupational Health and Safety and the Regulation on Health and Safety Conditions in the Use of Work Equipment issued under this law. Generators are listed among the equipment subject to periodic inspection within the scope of work equipment periodic inspection, and unless a different period is defined in the relevant standards, the maximum generator periodic inspection interval is accepted as one year. Additional inspection may also be required after installation before first use, after major maintenance or repair, and after relocation for non-mobile equipment. Therefore, all generator installations, especially those used for emergency and uninterrupted power purposes, must be subjected to periodic inspection at least once a year. For related context, see Bursa High Voltage (HV) and Medium Voltage (MV) Services.
Which generator systems are inspected
Our Bursa generator periodic inspection service covers diesel, natural-gas and mobile generator sets in critical buildings such as hospitals, data centers, banks, telecom facilities, industrial facilities, shopping centers, hotels, logistics warehouses and public buildings. Within this scope, the generator engine, alternator, power and control panels, automatic transfer panel (ATS/AMF), cable and busbar connections, grounding and equipotential bars, generator room architecture and ventilation are evaluated holistically. In synchronized generator groups, synchronization settings and maintenance records are also considered when planning the periodic inspection. For related context, see Bursa HV Operation Supervisor and High Voltage Responsibility.
Site preparation and document review
Before arriving on site, generator technical documents, nameplate data, previous generator periodic inspection and examination reports, generator maintenance contract and maintenance records if any, fault reports and operating instructions are reviewed. The facility's operating order, sensitivity of critical loads, minimum tolerated outage duration and generator starting scenarios such as manual, automatic or synchronized operation are evaluated, and a facility-specific periodic inspection plan is prepared and applied on site.
Visual and mechanical examination
During the visual and mechanical examination stage, oil and fuel leaks on the generator engine, hoses and connection points, radiator and cooling circuit, fan belts, exhaust line, vibration mounts, chassis and foundation bolts, enclosure and sound insulation, fuel tank and drainage arrangements are checked in detail. In addition, critical topics such as battery and starter circuit, battery charger rectifier, battery cables and oxidation, looseness and corrosion at terminals are reviewed. The traces and conformity of oil/filter changes performed within diesel generator periodic maintenance are also assessed at this stage.
Electrical measurements and function tests
During electrical testing, insulation resistance at the generator output, grounding continuity and continuity of protective conductors, residual current and protection devices, selection and settings of short-circuit and overcurrent protection elements, phase sequence, voltage and frequency values, and voltage-frequency behavior under load are measured. In facilities where required, heating checks with a thermal camera, load-bank tests or controlled loading with facility load are applied to assess the practical performance of the generator.
ATS/AMF and synchronization checks
During the inspection, function tests of the generator control system and automatic transfer panels (ATS/AMF) are carried out. A grid failure scenario is simulated and automatic start/stop function, load taking and return of load to the grid are observed. In synchronized generator groups, synchronization, load sharing, cos phi and power factor control, parallel operation scenarios and operating conditions of protection relays such as over/under voltage, frequency, phase sequence and imbalance are checked. In this way, periodic inspection and maintenance records of synchronized generators are linked together.
Generator room and safety conditions
In generator room and installation periodic inspection, the adequacy of natural and/or mechanical ventilation, fresh-air and hot-air discharge directions, whether exhaust gas is discharged without creating risk for people or the building, fuel tanks and fuel storage areas, fire detection and extinguishing systems, emergency stop buttons, emergency lighting, escape routes and warning signs are evaluated from an occupational health and safety perspective. Detected nonconformities and recommended corrective actions are clearly stated in the report so that improvement steps for both occupational safety and fire/explosion risk become concrete.
Assessment of test results
Measurement and function test results are not evaluated one by one in isolation; they are interpreted together with the facility's operating scenario. Voltage and frequency stability, insulation resistance, grounding continuity, protection settings, ATS/AMF transfer behavior, heating under load and the generator's ability to supply critical loads are assessed together. This makes it possible to identify not only out-of-limit values, but also weak points that may create future fault, fire, explosion, operational interruption or energy continuity risks.
Generator periodic inspection report
The generator periodic inspection report consists of inspection date, location and description of the generator, brand/model and power information, brand/model and calibration information of the test devices used, visual and mechanical examination results, measured electrical values, function and load test results, detected nonconformities and their severity levels, and conclusion-recommendations. The report is prepared in accordance with periodic inspection criteria published by the Ministry of Labor and Social Security and the relevant EMO / generator periodic inspection form format, and it is used as a technical document showing that your periodic inspection obligation has been fulfilled in official audits.
Authorized personnel and reporting
Generator periodic inspection must be carried out by persons who are authorized to perform periodic inspections of work equipment, come from the relevant technical discipline and meet EKİPNET registration requirements, or by authorized inspection bodies. In practice, the electrical safety, protection, automation and grounding aspects of the generator are evaluated with electrical or electrical-electronics engineering competence. For the report to be accepted in official audits, calibration details of measuring instruments, applied test methods, detected nonconformities and the information of the authorized person issuing the report must be clearly stated.
Relationship with generator periodic maintenance
The difference between generator periodic inspection and generator periodic maintenance should be emphasized. Periodic maintenance includes oil, fuel, air and oil filters, antifreeze, belts, connections, cleaning and adjustment operations performed based on manufacturer recommendations by operating hours or periods. Periodic inspection is a safety, conformity and documentation-focused examination activity that must be carried out at least once a year according to regulations. The healthiest approach is to confirm the system officially with independent inspection and examination after maintenance activities carried out through regular generator service and, where applicable, a generator maintenance contract.
Service scope for facilities in Bursa
We plan Bursa generator periodic inspection services for industrial facilities, shopping centers, hospitals, data centers, hotels, logistics warehouses, public buildings and campus structures operating in Nilufer, Osmangazi, Yildirim, Gursu, Kestel, Inegol, Gemlik, Mudanya, Karacabey, Mustafakemalpasa and the organized industrial zones of Bursa. A site-specific checklist is prepared for each facility by considering generator capacity, fuel type, operating scenario, critical load profile and generator room conditions.
Inspection interval and interim checks
We can support our Bursa generator periodic inspection services with interim inspections every six months in high-risk and critical facilities, while taking the annual statutory inspection as the basis according to the risk level and operating conditions of your facility. In this way, an additional safety level beyond legal requirements is provided especially for hospitals, data centers and businesses where uninterrupted power is critical. Your Bursa generator maintenance and service needs are also addressed within this planning so that maintenance and inspection processes become compatible with each other.
Nonconformities identified during inspection are classified under electrical safety, mechanical safety, fire and explosion risk, automation functions, generator room conditions and documentation deficiencies. Issues such as loose connections, insufficient ventilation, incorrect exhaust routing, fuel line risk, missing emergency stop arrangement, weak grounding, incorrect protection setting or unstable operation under load are stated clearly in the report. For each nonconformity, the priority level, recommended corrective action and, where necessary, the need for retesting are also specified.
EKİPNET and OHS-KATIP processes
The generator periodic inspection reports we prepare can be used as supporting documents for keeping periodic inspection records of work equipment up to date through EKİPNET and for occupational health and safety processes managed through OHS-KATIP, such as risk assessment, annual plan, emergency plan and explosion protection document. The classifications and recommendations in the report guide your occupational safety specialist and maintenance team in planning generator investments, maintenance programs and improvement works.
