Operation, Maintenance and retrofitting services for HV Power Plants

In the scope of 7/24 unlimited amendatory maintenance services, failures and breakdowns are covered along with Assessment-Analysis-Reporting services; operation of the substation is guaranteed by periodic contacts. All the test procedure of the electrical devices, included in Periodic (Preventive) Maintenance Services, are done according to Employer’s needs and IEC Standards. Supervising and Consulting works for Preventive Maintenance services include installing monitoring systems and planning the maintenance. Consulting services for ensuring operating efficiency and control are provided. In this regards Project errors and Application flaws are avoided; projects are revised accordingly. Adaptations for newer systems are provided.
