Electrical Systems

We focus on heavy-current electrical systems:

  • In power plants, electrical stations up to 110 kV
  • Industrial facilities
  • Building electrical installations - in industrial facilities and in administrative buildings

Provided services

  • Compilation of design documentation of all stages
  • Studies (including calculation of financial costs, calculations of short-circuit ratios)
  • Basic design
  • Detail design
  • As-Built documentation
  • Documentation falling under the building permit process (e.g. documentation for building permit, documentation for construction, ...)

Other engineering services:

  • Author supervision
  • Consulting and advisory services
  • Network calculations (short-circuit ratios, voltage ratios, power balances, ...)

Designed facilities

  • VHV substations 110kV (power part from the input portal, relevant control circuits, protection, construction part subcontracted)
  • HV substations – primary and secondary distribution of 6 kV, 10.5 kV for power plant on-site consumption or industrial operations. Secondary distribution 22 kV for industrial operations. Design of the power, control and management part including protections
  • Power transformers, distribution transformers - primary and secondary distribution of power plant on-site consumption, industrial operations
  • LV substations – conventional main and secondary cabinets up to 5000 A for distribution; modular switchboards up to 2500 A; design of the power and control parts
  • Sources of emergency power supply – diesel generators, rectifiers, inverters, UPS, station batteries; network topology design, including source dimensioning for steady and transient conditions
  • Cable systems – LV and HV cabling; design of conventional or fire-resistant cabling, including routing and accessories
  • Cable route systems – conventional modular routes or routes with fire integrity; design including auxiliary structures, control of mechanical load or occupancy of trays
