  • Hospitals, shopping malls, campuses, warehouses and commercial buildings requiring documented safety checks
  • Facility managers who need technical reporting, maintenance follow-up, testing or proposal planning

Short Technical Definitions

The voltage level mentioned in service scopes affects the engineering method, authorization need and field safety approach.

LV
Low voltage installations generally cover electrical infrastructure on the consumer side, including panels, circuits and internal installations.
MV
Medium voltage installations cover transformer substations, MV switchgear, protection equipment and related operating safety processes.
HV
High voltage installations require authorized technical responsibility, switching discipline, maintenance follow-up and documented safety control.

Why Choose Pow-Sys?

For electrical installations, the right decision depends on competent field assessment, clear reporting and traceable follow-up.

Authorized engineering perspective

Service planning is handled with an electrical engineering approach, EMO/SMM transparency and documented technical review.

Field-based reporting

Findings are not kept as verbal comments; they are converted into report outputs, corrective action notes and follow-up items.

Integrated service planning

Operation responsibility, periodic inspection, testing, maintenance and proposal preparation can be evaluated together when needed.

Clear communication

The proposal scope, required information, expected outputs and post-service follow-up steps are made understandable before work starts.

For electrical installations, the final technical assessment must be made through authorized field inspection, current documentation, applicable regulations and site-specific engineering review.

Field Experience and Reporting

Pow-Sys evaluates each facility according to its site conditions, service need and expected reporting output.

Facility categories

Industrial facilities, OIZ factories, private power rooms, hospitals, shopping centers, commercial buildings and power generation sites.

Common request types

Operation responsibility, documented inspections, grounding and lightning protection measurements, equipment testing, relay checks and power quality review.

Typical report outputs

General condition assessment, nonconformity list, risk level, photo-supported finding, corrective action and follow-up date.

Short Field Case Examples

The examples below summarize recurring field situations evaluated during electrical engineering, inspection and reporting work.

Private power-supply industrial facility

Facility type
OIZ factory with a private power room
Date / location
Bursa, anonymous facility type, recent field assessment
Problem
The power room labels and the existing single-line diagram did not fully match, increasing switching procedure risk.
Control / test
Power room, MV equipment labels, single-line diagram, switching instructions and maintenance records were reviewed together.
Standard / method
Field assessment was made according to MV/HV operating safety practice, switching discipline and current technical documentation consistency.
Measured findings
Different naming was observed between several field labels and project documents; maintenance follow-up notes were not consolidated.
Quantified output
Measured output: 1 power room, 6 MV equipment positions, 1 single-line diagram and 8 documentation/control findings were evaluated.
Output
A technical report, corrective action list, documentation revision need and risk-level follow-up note were prepared.

Periodic inspection planning

Facility type
Commercial building with electrical installation and grounding scope
Date / location
Turkey, anonymous commercial facility, periodic planning work
Problem
Grounding, lightning protection and electrical installation inspection dates were tracked in separate records.
Control / test
Previous reports, measurement dates, corrective actions and annual inspection needs were reviewed together.
Standard / method
The scope was organized according to work equipment periodic inspection obligations and electrical installation safety practice.
Measured findings
Report dates, measurement follow-ups and corrective action notes were not managed in one common tracking list.
Quantified output
Measured output: 3 inspection groups, 12 report/date records and 1 combined follow-up calendar were organized.
Output
A combined inspection calendar, report tracking list, priority level and follow-up plan were prepared.

Power equipment maintenance tracking

Facility type
Energy room serving production loads
Date / location
Bursa, anonymous facility, maintenance follow-up
Problem
Maintenance records, oil analysis need and field observations needed to be evaluated before the next service period.
Control / test
Power equipment condition, oil leakage risk, ventilation status, MV area access and previous maintenance notes were checked.
Standard / method
Assessment was made with maintenance practice, visual inspection discipline and test/oil analysis follow-up logic.
Measured findings
Visual observations and maintenance notes showed items that required planned follow-up before the next outage window.
Quantified output
Measured output: 1 main power equipment group, 1 MV area, 5 maintenance headings and 3 priority follow-up actions were documented.
Output
Maintenance, test and oil analysis recommendations were documented with responsible follow-up steps and risk priority.
