Diagnostic and service

Solární panely

We believe diagnostics is of overall importance for the maintenance of electrical equipment .Modern diagnostic instruments show invisible faults one you cannot find during classic revision of electrical equipment. Costs of analysis are decisively lower than resulting of equipment crashes.


Diagnostic measurement advantages :

  • analysis and operating ability of electrical equipment in service
  • analysing “invisible faults“ = prevention of equipment crash = costs savings
  • preplanning of maintenance, repairs and short stillstands
  • measurement protocols, diagrams, evaluation and recommendation for service and repairs


After service

After-service is provided either in the daily way or on a permanent service contract basis. If the permanent service contract is not made , we provide the service operation on a technically explicit order basis. After the electrical equipment inspection our workers will review the technical state of the equipment and will calculate the costs. The settlement day is specified in the order confirmation and depends on the date of spare-parts delivery. In case of breakdown conditions we are prepared to be on the site within 24 hours after given written notice.



Our service workers are trained and certified by famous producers and they are able to solve the most demanding requirements. We provide the maintenance of the following ABB equipment types :

  • metal-clad air-insulated switchboards SR and ZS1
  • circuit breakers HL, HG, VF, VD, VMV
  • switch – disconnectors OK and NAL
  • vacuum contactors SVW

and the following EATON – HOLEC equipment:
