Low voltage industrial installations - Design (A1212)

Duration
4 Days
Who should attend?
Technicians involved in study and design
 
What will I learn from this course?
  • Select the appropriate switchgear and lines
  • Estimate the value of short circuit currents
  • Understand electrical constraints and identify when support is needed
  • Improve dialog with specialists operating on site
Topics
Electrical installation overview
  • Standard NFC 15-100 (France) and IEC (international)
  • Voltage domains and naming (LV, MV, HV)
  • Neutral systems in LV Earthing design
 
  • Users features (panels, asynchronous motors)
  • Sources features (HV grid, transformers, UPS)
Switchgear
  • Definition, function, operation, features, symbols
  • Circuit breakers, disconnectors, switches, contactors, fuse wires, relays
 
  • Switchgear twinning, selectivity
Electrical line
  • Features
  • Dimensions for steady states (overload, voltage drop)
 
  • Dimensions for transitory states (short circuit, start)
  • Electro dynamical effort between conductors
Default current estimation
  • Electricity basics
  • Source is a transformer
 
  • Transformer protection
  • Fault current calculation in different points of the grid
Case study
  • Design of one part of a plant: selection of the equipment, comparison of the different solutions
