Transformer Repairs & Grid Connection Services

Power oil transformers are devices designed for long-term operation, but the latter is subject to regular checks of oil parameters and diagnostics of the transformer status. In case of deterioration
of the required parameters of the transformer or its failure, we review its condition, suggest a suitable method for its repair, which we then also provide. We carry out repairs and repairs for all voltage levels, including special transformers designed for heavy operation — furnace and test transformers.

The services provided by us include in particular:

• Regular revisions of transformers and branch switches
• Designs and implementation of repairs and refurbishments of transformers and branch switches
• Designs and implementation of modifications of radiators and fans to improve cooling parameters of transformers
• Design and implementation of transformer soundproofing systems

For the transmission and distribution system, we also offer services and supplies focused on control systems:

• Designs and implementation of ASRU system for providing voltage control support service using reactive power SRUQ
• ASRU certification tests for the provision of voltage control support service using reactive power SRUQ
• Projects, implementation and certification of PLC terminals for the provision of system services

We also provide our customers with services for newly connected and reconstructed electricity sources:

• Development of a study of connectedness
• Measurement of the quality of electricity for connection of the source to the system
• Verification of the function of system stabilizers according to the CEPS a.s. methodology for large rotary sources connected to the transmission system.
