Bursa Grounding Measurement and Report

Grounding installation periodic inspection is the process of measuring and examining the protective grounding, functional grounding, lightning protection grounding and equipotential bonding of a facility at defined intervals. In businesses in Bursa, this process is often referred to as grounding periodic inspection, grounding installation periodic examination, grounding measurement, grounding test or grounding report. Their common purpose is to verify the effectiveness and continuity of the grounding system in a way that reduces electric shock, arc-flash and fire risks. For related context, see Bursa Battery Periodic Inspection.

It should be remembered that periodic inspection and periodic maintenance are different concepts. Grounding installation periodic inspection is an official periodic examination that documents the compliance of grounding through independent measurements, tests and visual checks. Periodic maintenance covers interventions such as tightening connections, cleaning corrosion and renewing conductors, and it does not replace a grounding installation periodic inspection report. What is requested during inspections by a labor inspector, insurance company or certification body is a periodic inspection report prepared by an authorized engineer or an accredited Type A inspection body. For related context, see Bursa Generator Periodic Inspection.

The legal basis of grounding periodic inspection is Law No. 6331 on Occupational Health and Safety and the Regulation on Health and Safety Conditions in the Use of Work Equipment, published under this law on 25.04.2013 with number 28628. In the field, this text may be referred to as the work equipment periodic inspection regulation, electrical grounding periodic inspection regulation, grounding periodic inspection interval or simply the grounding regulation. In addition, the Regulation on Grounding in Electrical Installations, EMO grounding rules and the relevant TS EN standards define grounding resistance limit values, measurement methods, soil resistivity measurement and report format. For related context, see Bursa Transformer Maintenance, Testing, Oil Analysis and Fault Repair.

Grounding installation covers the main grounding bar, foundation grounding, ring earth electrodes, local earth electrodes, electrical installation grounding bars, panel and machine body grounding, lightning protection grounding and equipotential bonding. In factories in Bursa, production facilities in organized industrial zones, logistics warehouses, shopping centers, hospitals, hotels and office buildings, all metal bodies of electrical machinery and equipment must be connected to suitable protective grounding. Grounding periodic inspections verify whether this entire system operates continuously, with low impedance and safely. For related context, see Bursa Electrical Contracting Services.

In the field, grounding periodic inspection is generally carried out in three steps: preparation and site survey, visual examination and electrical measurements. During the site survey stage, the grounding installation diagram is created; which panel, which machine and which lightning protection system are connected to which earth electrode or main grounding bar is determined. Previously prepared grounding measurement reports, electrical installation conformity reports, projects and soil resistivity reports, if any, are reviewed; measurement points, test methods to be used and grounding periodic inspection form details are clarified.

During the visual examination stage, conductor cross-sections, terminal connections, corrosion and mechanical damage, cable and busbar routes, the arrangement of the main grounding bar and equipotential bars, down conductors and connection points of the lightning protection system, panel body grounding connections, labels and warning signs are checked. In protective grounding periodic inspection, the grounding continuity of machine bodies and panels, coordination with residual current devices (RCDs), and suitability of thermal-magnetic protection devices are evaluated. Corrosion, loose connections, broken conductors, incorrect cross-section selection or non-standard connections are specified in the report as major nonconformities.

During the electrical measurement and test stage, grounding resistance measurement methods such as the three-point method, 62% rule and clamp-meter measurement, grounding continuity tests, step and touch voltage assessments, soil resistivity measurement by the Wenner method and, where required, SELVAZ grounding performance tests in switchyards are applied. In this way, not only the magnitude of grounding resistance but also whether the system can safely conduct the fault current that may pass through it during a fault is analyzed.

Grounding measurement results are evaluated by taking the Regulation on Grounding in Electrical Installations, the relevant standards such as TS EN 62305 and TS EN 60364-4-41, and distribution company / EDAS practices into account. Permitted limit values and safety criteria may vary for different facility types such as residential buildings, commercial buildings, industrial facilities, explosive atmospheres and hospitals. Therefore, a grounding measurement report does not only answer the question of how many ohms were measured; it also answers whether this value is safe under the existing conditions and whether the protection devices will open within the required time.

The grounding periodic inspection interval is one of the most frequently asked topics in businesses. The Regulation on Health and Safety Conditions in the Use of Work Equipment generally defines the maximum inspection period for electrical installations and grounding installations as one year. Therefore, the practical answer to how often grounding measurements should be performed is at least once a year for most businesses in Bursa. In humid, corrosive, chemically exposed, extremely dusty, high mechanical vibration or explosive atmosphere (Ex zone) facilities, this interval should be shortened further; risk analysis, manufacturer recommendations and functional grounding periodic inspection results should be evaluated together.

Who performs grounding periodic inspection According to the regulation, electrical grounding measurements and grounding installation periodic inspection must be carried out by electrical / electrical-electronics engineers with the required qualifications or accredited Type A inspection bodies. Measurements must be made with calibrated instruments, the method used must be stated in the report, measurement dates and device calibration information must be included, and the results must be delivered as a signed and sealed periodic inspection report.

As Pow-Sys Güç Sistemleri, we provide Bursa grounding periodic inspection and Bursa grounding measurement services throughout Bursa, especially in Nilufer OSB, Demirtas OSB (DOSAB), Hasanaga, Kayapa, Kestel, Gursu, Inegol and surrounding organized industrial zones. For businesses looking for Bursa grounding measurement, Bursa grounding report, Bursa electrical and grounding measurements or Bursa grounding installation periodic inspection, we first create an inventory of the existing grounding system, then plan measurement intervals and the next periodic inspection date together.

During grounding periodic examination, ring earth electrodes, column and panel grounding, machine body grounding, functional and protective grounding, and the lightning protection system are traced end-to-end starting from the main grounding bar. Values for each measurement point are recorded and clearly shown in the grounding measurement report. For resistance values that are critically high, technical solutions such as adding new electrodes, increasing conductor cross-section, renewing connection points or preparing additional grounding projects in areas with high soil resistivity are recommended.

EKİPNET is the online system where periodic inspections of work equipment are monitored by the Ministry of Labor and Social Security. Whether your grounding installation periodic inspection reports need to be entered into EKİPNET should be evaluated according to the equipment type and current legislation. Your occupational safety specialist appointed through OHS-KATIP uses grounding periodic inspection reports while preparing the risk assessment, annual work plan, emergency plan and explosion protection document. We structure our reports to provide input for your EKİPNET and OHS-KATIP processes.

Bursa grounding periodic inspection prices are determined according to the size of your facility, the number of grounding points and measurements, the number of lightning protection systems, whether there is a switchyard or transformer substation, additional tests to be performed such as soil resistivity measurement, SELVAZ test or thermal camera scan, requested report language, delivery time and location. After preliminary survey or project review, we provide clear pricing and, if you wish, alternative proposal scenarios for different scopes.

When needed, we plan grounding installation periodic inspection together with electrical installation periodic inspection, lightning protection tests and MV/HV maintenance-test works. In this way, both the electrical installation and grounding system are inspected in the same period, and the relationship between them can be read in a single report set. For detailed information, you can also review our Bursa electrical installation periodic inspection, Bursa HV/MV maintenance and testing and Bursa transformer maintenance, testing and oil analysis pages.

We configure our Bursa grounding installation periodic inspection service, whenever possible, as an annual contracted structure rather than a one-time service. In this way, your grounding measurement history is kept, point-based trends can be monitored and the improvement steps that must be completed before the next periodic inspection date can be managed more systematically. This model turns the safety of your grounding system, periodic inspections of your electrical and grounding installations, and your occupational health and safety management into a sustainable whole.
