Service Details
Facilities operating at high voltage (HV) and medium voltage (MV) levels in Bursa and its surroundings; Factories, industrial establishments within OIZs, energy production facilities, large commercial buildings and infrastructure projects need regular testing and maintenance. The services we describe on this page; It covers the testing, maintenance and repair work of your HV/MV lines, cables and cells in the field.
The study process usually begins with site reconnaissance. The current status of your HV/MV lines, cables, MV cubicles, transformers and grounding devices is examined; single line and protection schemes are reviewed. At this stage, risky areas, access restrictions and the necessary downtime plan for maintenance are determined.
In HV/MV cable tests; Insulation resistance measurements, if necessary, VLF or similar high voltage resistance tests, sheath tests and phase sequence/length measurements are performed. In case of a fault, special devices are used to detect the cable fault point and the fault location is reduced to a narrow area before excavation.
In thermal camera controls; MV cubicle busbars, cable headers, transformer connections, disconnector-breaker contacts and inter-panel connections are scanned. Higher-than-normal hotspots may indicate problems such as loose connections, load imbalance, or equipment aging. These points are highlighted as separate headings in the report.
All data obtained during maintenance and testing studies are interpreted taking into account the relevant standards (TS/IEC series), manufacturer recommendations and the risk profile of your facility. Short-medium-long term action recommendations are prepared for values close to the critical level; thus budget planning and downtime management become more predictable.
In HV/MV repair works; Depending on the type of fault detected, interventions such as cable splice and header renewals, connection and bushing replacements, breaker-disconnector mechanical revisions, surge arrester and measurement transformer replacements, and rearrangement of busbars are planned. When necessary, coordination is provided with the manufacturer or authorized services.
At the end of all maintenance, testing and repair activities; A detailed report is prepared, including measurement results, devices used, field notes, photographs and, if necessary, thermal images. The report includes both an assessment of the current situation and suggestions for improvement; The report can be used as a reference in official audits.
Service fee; It is calculated on a project basis according to line and cable lengths, number of MV cubicles, number of transformers, desired test types, field location and planned downtime. After the survey, we prepare clear and comparable offers for different coverage options.

Frequently Asked Questions
What types of HV and MV facilities do you serve?
We offer testing, maintenance and repair services for factories in organized industrial zones, energy production and distribution facilities, large commercial buildings, infrastructure projects and municipal/public HV/MV facilities. Transformer centers, MV cubicles, cables and lines are included in this scope. For detailed transformer-specific testing and oil analysis Bursa transformer maintenance, testing and oil analysis You can review our page.
What tests are performed in HV/MV maintenance?
Depending on the need, MV cubicle maintenance checks, breaker and disconnector function tests, HV / MV cable insulation and VLF tests, grounding and lightning rod measurements, thermal camera scans and partial discharge / corona checks are applied in some projects. The test package is determined according to the condition of your facility. For official measurement reports and OSH legislation side periodic inspection and inspection We work integrated with our service.
Is it necessary to completely shut down the facility for maintenance and testing?
Some visual checks and thermal scans can be performed while power is on; However, for most electrical tests the line or cell must be safely de-energized. During the planning phase, we consider options such as gradual stopping or weekend/night work to minimize production loss.
How do you determine periodic maintenance intervals?
We take into account the facility type, equipment age, loading profile and previous test results. We generally recommend at least one comprehensive HV/MV maintenance per year; We plan additional intermediate checks in risky or critical facilities. We use this plan to manage the long-term business and regulatory side from a single source. SA operation responsibility We can design it together with our service.
Can we also receive service for HV/MV facilities outside Bursa?
Our main service area is Bursa and nearby provinces. Where appropriate in terms of logistics and planning, we can also provide testing, maintenance and repair services for HV/MV facilities in surrounding provinces. For detailed information, a brief description of your facility will be sufficient for us to plan according to scope and location.
