Bursa Generator Periodic Inspection

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.

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.

Generator systems used as work equipment must be assessed under Law No. 6331 and the Regulation on Health and Safety Conditions in the Use of Work Equipment. The applicable equipment category, relevant standards and site conditions determine the inspection scope and interval. A one-year maximum applies where the applicable standards do not specify a different period; it must not be presented as a universal rule for every generator installation. Installation, major changes, repairs or relocation may also require a separate assessment before the equipment is returned to service. The proposal records the applicable basis and any shorter interval justified by the site risk assessment.

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.

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.

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.

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.

Generator control and ATS/AMF function tests are selected under the agreed test plan. A simulated grid failure, load transfer or return-to-grid test is performed only where authorized after critical loads, backup arrangements and the permitted outage are reviewed. For synchronized groups, the applicable synchronization, load-sharing, power-factor and protection functions may also be checked. The report identifies the scenarios actually tested, conditions, results and any exclusions; it does not guarantee performance during every future outage.

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.

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.

The generator periodic inspection report identifies the inspection date and location, generator model and rating, instruments and calibration status, examination findings, measured electrical values, function or load-test conditions, exclusions and nonconformities. Applicable Ministry inspection criteria and report requirements are used where published for the equipment; otherwise the relevant standards and regulatory report requirements define the method. A professional association template is not by itself a universal statutory format. The report is signed by a person who meets the applicable equipment-specific authorization conditions and records the work actually performed; it does not guarantee an official audit outcome.

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.

Generator maintenance consists of manufacturer-directed service work such as fluids, filters, connections and adjustments. Periodic inspection is a separate examination and reporting activity at the applicable interval. Annex III uses one year where relevant standards specify no period; risk or manufacturer instructions may require earlier checks. Maintenance records do not replace the statutory inspection report.

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.

For critical facilities in Bursa, interim generator checks can be agreed in addition to the applicable periodic inspection programme. Their scope and frequency depend on the relevant standards, manufacturer guidance, operating conditions, previous findings and site risk assessment; a six-month visit is an optional planning choice rather than a universal statutory requirement. Maintenance, service repairs, load testing and formal periodic inspection are identified separately in the proposal, including outage permissions and backup-power arrangements.

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.

Before a mandatory generator inspection, the employer and authorized inspector must approve an İSG-KATİP contract at least one day in advance. EKİPNET records the authorized person. The signed inspection report belongs in the facility records; its findings support risk assessment, maintenance planning and corrective actions.
