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
