What is high voltage operation responsibility
High voltage operation responsibility in Bursa is a technical responsibility service carried out by an authorized electrical engineer to ensure that MV/HV facilities above 1 kV are operated safely, systematically and in compliance with applicable regulations. As Pow-Sys Güç Sistemleri, we provide HV operation supervisor services for privately owned transformer facilities, factories in Organized Industrial Zones, hospitals, shopping malls, hotels and large commercial facilities in Bursa and surrounding areas; we regularly manage periodic inspections, reporting and technical follow-up processes. For related context, see Bursa High Voltage (HV) and Medium Voltage (MV) Services.
High voltage operation responsibility is not only a contract or signature process. Transformer substations, MV switchgear, switching procedures, protection systems, grounding installations, maintenance planning, periodic inspections and the safe working habits of operating personnel are all important parts of this service. For this reason, choosing the right HV operation supervisor is critical for both electrical safety and operational continuity. For related context, see Bursa Grounding Measurement and Report.
As Pow-Sys Güç Sistemleri, we provide high voltage operation responsibility, transformer operation responsibility and transformer substation operation follow-up services in Bursa and surrounding areas on a contractual basis. Within the scope of the service, we inspect the current condition of the facility, report deficiencies, prepare a periodic visit plan and help make the technical processes of the business more organized. For related context, see Bursa Periodic Inspection and Examination Service.
HV operation supervisor and employer responsibilities
The HV operation supervisor is an electrical engineer whose competence is documented within the current YGTİS authorization framework and implementation principles defined by the Chamber of Electrical Engineers. The engineer undertaking the operation responsibility monitors the safe operation of the MV/HV facility, guides the employer and facility management on technical issues, follows up the necessary inspections and reports identified risks in writing. For related context, see Bursa Battery Periodic Inspection.
Operation responsibility in high voltage facilities above 1 kV is evaluated within the framework of the Electrical High Current Installations Regulation, EMO regulations and relevant technical legislation. In this scope, the determining factor is not only transformer power; the fact that the facility is supplied from a voltage level above 1 kV, its MV/HV switchgear structure, transformer substation location and operating conditions are evaluated together.
For transformer substations supplied at MV/HV voltage levels and falling within the scope of facilities above 1 kV, working with an authorized HV operation supervisor in accordance with relevant regulations is required. This responsibility is important for ensuring electrical safety, organizing maintenance and inspection processes, keeping switching operations under control and reducing the risks of possible faults or occupational accidents.
The main duties of the HV operation supervisor include monitoring the condition of the transformer substation and MV switchgear, preparing switching instructions, establishing safe working procedures, providing technical control during maintenance and repair activities, informing operating personnel when necessary and recording all tests and inspections performed.
The employer's responsibility is not limited to signing a contract. The business must provide the necessary access for the HV operation supervisor to perform their duties, allocate a budget for maintenance and repair, provide personal protective equipment and safety equipment, evaluate technical deficiencies reported in writing and ensure compliance with safe working instructions.
Site survey, inspection plan and reporting process
Pow-Sys Güç Sistemleri carries out HV operation responsibility services with an active field-based technical follow-up approach. Our aim is not only to complete the regulatory compliance process, but also to reduce fault risks in the transformer substation, identify maintenance needs in advance, improve personnel safety and make the electrical infrastructure of the facility more sustainable.
Our HV operation responsibility process starts with a site survey. In the first stage, transformer power, number of MV/LV switchgear cells, single-line diagram, current maintenance status, grounding structure, switching arrangement, protection equipment and operating conditions of the facility are inspected. After this inspection, the service scope, visit frequency, reporting format and contract conditions are clarified.
After the contract process is completed, a regular inspection plan is prepared for the facility. During periodic visits, MV switchgear, transformer substation, grounding installation, warning signs, switching equipment, fire and occupational safety elements, maintenance records and actions stated in previous reports are checked. Identified deficiencies are reported to the business in writing.
The inspections carried out within the scope of HV operation responsibility include general condition checks of MV switchgear, visual inspection of circuit breakers and disconnectors, earthing switch checks, transformer oil level and leakage checks, transformer temperature indicator checks, ventilation condition, grounding connections, single-line diagram, switching instructions, warning signs and operating safety equipment.
Depending on the needs of the facility, grounding measurements, lightning protection system checks, internal electrical installation inspections, capacitor bank panel checks, thermal camera inspections, relay tests, power quality measurements and transformer tests can also be planned separately. Some of these works may be carried out together with our periodic inspection and control services.
Transformer substation, OIZ and Bursa service scope
In practice, transformer operation responsibility and high voltage operation responsibility are often evaluated within the same service scope. In facilities with privately owned transformers, the responsibility is not limited to the transformer itself; MV switchgear, circuit breaker-disconnector equipment, grounding system, switching procedures, protection scheme and the overall electrical safety of the facility are also included in the operation responsibility scope.
HV operation responsibility service is especially important for industrial facilities in Bursa, particularly those located in Organized Industrial Zones. We carry out site surveys, contracts, technical inspections and reporting processes for privately owned transformer facilities in Bursa OIZ, Demirtaş OIZ, Nilüfer OIZ, Kayapa OIZ, Hasanağa OIZ, Kestel OIZ, Gürsu, Osmangazi, Nilüfer, İnegöl, Gemlik, Mudanya and Karacabey.
Facilities that most commonly need high voltage operation responsibility services in Bursa include manufacturing plants, textile factories, automotive supplier plants, food production facilities, cement and mining facilities, hospitals, shopping malls, hotels, public buildings, large commercial structures and residential-commercial complexes with transformer substations.
How is the HV operation responsibility fee determined
The fee for HV operation responsibility is determined according to transformer power, number of transformers, number of MV/LV switchgear cells, facility location, visit frequency, scope of tests to be performed, emergency support and reporting details. As Pow-Sys Güç Sistemleri, we prepare a transparent, understandable and sustainable offer for your facility in Bursa by taking into account the current EMO minimum fee tariff and the service scope.
Regulatory compliance assessment is an important part of the HV operation responsibility service. In this assessment, the legal obligations, technical deficiencies, safe working conditions, maintenance needs and reporting structure of the facility are evaluated together. This enables the business to control not only the documentation process, but also the real risks in the field.
Pow-Sys service approach and integrated technical support
When you work with Pow-Sys Güç Sistemleri, you gain not only an engineering company that manages the contract process, but also a technical solution partner that periodically follows up your transformer substation, provides technical support during switching and maintenance processes, reports deficiencies in writing and contributes to your long-term operational safety.
We can provide our HV operation responsibility service in an integrated manner with MV/HV testing, maintenance and repair services in Bursa, transformer testing and oil analysis, relay tests, capacitor bank inspections, harmonic and power quality measurements, grounding measurements and periodic inspection services.
For businesses with new facility installations, power increase projects, transformer substation revisions or distribution company procedures, we also work together with our LV/MV/HV design and consultancy services. This allows project, acceptance, operation responsibility, maintenance and periodic inspection processes to be managed more systematically from a single point.
If you would like to find out whether your facility falls within the scope of HV operation responsibility, request a technical condition assessment for your existing transformer substation or receive an offer for your facility in Bursa, you can contact Pow-Sys Güç Sistemleri. Once you share your facility information, we can define the service scope suitable for your transformer structure and operating conditions together.
