Low voltage systems

Transformers / NS-HS equipment / distribution equipment

  • Conceptual design for switchgear installations, including supply of electrical data for construction
  • Generation of technical specification, RFQ documentation and processing of bids, clarification of technical issues
  • Placement of contracts for erection work, supervision of erection and commissioning
  • Documentation generation
  • Design of protection philosophy (over-current and short-circuit protection, maintaining selectivity, certification of short-circuit tolerance)
  • Automatic meter data acquisition and visualisation
  • Main contractor role also possible if client wishes

 

Medium voltage systems

Switchgear < 52 kV

Upgrading existing plants (retrofits)

  • Connection to switchgear control systems
  • Replacement of conventional protection devices with digital protection and fieldbus devices
  • Meter data acquisition for remote reading

  • Automatic generation of distribution drawings and single-line drawings
  • Cost-reduction of more than 20% by default selection of standard values and automatic selection of the most cost-effective wiring and protection components
  • Comprehensive data for complete documentation of the electrical system
  • Design of protective devices
  • Design of cables and wiring
  • Determination of power consumption
  • Determination of operating currents
  • Determination of voltage drops
  • Determination of short-circuit currents
  • Determination of turn-off times
  • Determination of selective protection
