Service Details
Within the scope of the study; Visual controls of MV cubicles, transformers, breakers and disconnectors, mechanical operability tests, inspection of locking-grounding systems, function tests of protection relays and other measurements deemed necessary are carried out at regular intervals. This makes it possible to take precautions before a malfunction occurs.
Employer; It is obligatory to check that the engineer who will undertake the task has the Electrical HV Facilities Operation Responsibility Authorization Certificate issued by EMO, to provide the necessary personal protective equipment and test equipment, to allocate a budget for maintenance-repair and to implement the written instructions of the transformer operation responsible engineer.
Legal basis of transformer operation responsibility; Electrical High Current Facilities Regulation and related standards published in the Official Gazette dated 30.11.2000 and numbered 24246. You can access detailed legislation information from the official links below:

Frequently Asked Questions
What does a transformer operation responsible engineer do and why is it necessary?
Transformer operation responsible engineer; He is the authorized electrical engineer responsible for the safe operation of MV/LV equipment in the substation, creating a maintenance plan, carrying out tests and measurements, and recording all processes. In order to reduce malfunctions caused by wrong maneuvers and negligence and to ensure the safety of life and property, working with the transformer operator is necessary both legally and technically. Also for general HV facility coverage SA operation responsibility You can also benefit from our service.
Is transformer operation responsibility and HV operation responsibility the same thing?
Although the two tasks are often carried out by the same person, their focuses are different. High voltage operation responsibility While focusing on the general operational safety of the facility and compliance with the legislation, transformer operation responsibility covers transformer-specific topics such as daily monitoring of the transformer and its connected MV/LV equipment, maintenance plan, oil and insulation controls, thermal monitoring. Technical tests and oil analyzes of the transformer are mostly Bursa transformer maintenance, testing and oil analysis carried out by our service.
What tests and checks do you do?
We carry out operations such as visual and functional checks on the MV cubicle and transformer, grounding (resistivity/cellase) measurements, lightning rod and lightning protection system tests, thermal camera heating checks, transformer oil and insulation checks, protection relay tests, compensation and energy quality measurements on a planned schedule. For more detailed HV/MV level tests and cable/cell maintenance HV/MV testing, maintenance and repair Our service comes into play.
How is the fee determined?
We prepare a project-based proposal according to the total transformer power, number of transformers and MV cubicles, size of the facility, frequency of visits and the scope of the requested tests and measurements. In pricing, the annual minimum wage tariff published by EMO is taken into account as the lower limit. Offer if you want; periodic inspection and inspection together with or in general SA operation responsibility It can be prepared integrated with the package.
Can we take responsibility for operating transformers for facilities outside Bursa?
Our main service area is Bursa; We are especially concentrated in organized industrial zones. However, when it is suitable in terms of planning and logistics, we can also provide transformer operation responsibility or consultancy services to factories, energy facilities and large structures in nearby provinces. For the project planning and commissioning side in new installation or power increase projects LV/MV/HV project design and consultancy We work in coordination with our team.
Do you have emergency support?
Within the scope of the contract; We maintain an emergency procedure that includes a 24/7 contact line, preliminary assessment by phone or online, and a rapid site visit when necessary. In case of malfunction, leakage current, sudden heating or equipment damage, the transformer operation responsible engineer coordinates the process from start to finish; if necessary HV/MV testing and repair and transformer maintenance, testing and oil analysis An intervention plan is created together with our teams.
