What is transformer periodic inspection?

Transformer (transformer 1-36 kV visual inspection and grounding system) periodic inspection is the process of checking whether the electrical transformer is operating safely, efficiently, and without interruption at certain intervals. The aim is to prevent the risks of malfunctions, fires, and power outages.

How is it done? (Briefly)

Visual inspection

Oil leakage, corrosion, and insulation condition are examined

Labels, warning signs, and locks are checked

Electrical checks

Primary-secondary voltage and current measurements

Insulation resistance and grounding check

Function tests

Operation of protection relays and switches

Level and temperature indicators in oil-filled transformers

How often is it done?

At least once a year

Again after a malfunction, maintenance, or unusual situation

Standards / legislation

Regulation on Electrical High Current Installations

Regulation on Health and Safety Conditions in the Use of Work Equipment

Who should do it?

• Equipment inspections must be carried out by authorized Electrical Engineers, Electrical and Electronics Engineers / Electrical Technicians holding Ekipnet "K" number, as determined by the equipment inspection organization.
