Maintenance

Our preventive and corrective maintenance services ensure constant electricity supply to our customers, under security and efficiency conditions.

 

Preventive and corrective maintenance for:

• overhead electric lines (LEA) and underground electric lines (LES) with voltages ranging between 0.4 – 110 kV;
• 110 kV/medium voltage transformer stations;
• medium voltage/low voltage transformer stations and supply sites;

 

Defectoscope  and testing of electric cables using high efficiency devices for quick location of cables faults with 0.4 and 110 KV operating voltage.

 

Identifying the cable routes and locating faults by:

• measuring the direct impulse reflection (differential measurement and contact measurement);
• short term stabilization of electric arc;
• voltage connection method;
• current impulse method;
