Protection & Control Design

Power system protection and control design

Acrastyle has significant experience in protection and control design with many thousands of LV, HV and EHV protection and control systems in use throughout the world. Its wide experience and in-depth expertise in protection and control design enables it to design the most complex power system schemes as well as providing elegant, simpler schemes for less arduous applications.

Protection and Control Design

The protection and control design process:

  • Begins with a detailed understanding of the planned power system configuration
  • Understands the power system operating parameters under both normal and fault conditions
  • Understands all the mechanical & electrical limitations that may be imposed by the site
  • Is carefully controlled with all stages checked and signed off

The process also allows:

  • Changes to be carefully logged and documented
  • Design version control & overall review before releasing to the customer for approval
  • Design freeze for manufacture
  • Modifications & change requests post freeze that are carefully reviewed and implemented once approved
  • System testing to the scheme drawings to test equipment, manufacture and design

Wherever possible, sophisticated CAD design software is used which can automatically:

  • Produce wiring lists & wiring diagrams
  • Assign and define terminal numbers
  • Ensure that no contact is incorrectly used more than once
  • Check that the correct maximum number of wires per terminal is not exceeded
  • Generate a detailed bill of material
  • Ensure that the devices incorporated from the Acrastyle pre-defined library are correctly represented and wired out

Where a scheme is going to replace part or all of an existing scheme in several project phases Acrastyle can provide detailed ‘red, green and black‘ drawings for each phase.

We use the latest AutoCAD 2015 software & can provide drawings & designs in all releases of AutoCAD DWG file in addition to DXF, DWF and Adobe PDF files. Drawings can also be provided for compatibility with other CAD packages on request.

Scanning and printing

Our protection and control design services are supported by our large format scanning capabilities, both on and off site, and also our large format plotting/printing services (up to A0 in colour or B/W).
