From beginner level to high-end specialist training.

capacitive couplings between transmission lines
Get a solid knowledge of working in the proximity of energized circuits...and learn how to realize projects safely.

Brief summary of the training content:


  • Basics of Electricity for better understanding of the working methods: To improve or to refresh the existing knowledge.

  • Grounding, minimum approach distances, earth faults, different star point groundings and their impact, electric and electromagnetic fields.

  • Approximated calculation of induced voltages for practical purposes.

  • Cradle block methods, calculation and choice of ropes and equipment, other stringing methods, practical tips and hints.

  • Safety measures, Safe-Work-Analysis.

A complete wrap-up of transmission line tension stringing for newbies, managers and experts.

Overhead conductor tension stringing on all kinds of transmission lines at all voltage levels.

Brief summary of the training content:

  • Theoretical background of tension stringing

  • Conductors, fiber optic cables, correct handling, etc.

  • Equipment and machines: Calculation of the appropriate machinery and equipment (calculated both approximately and very precisely upon request)

  • Project and site organization.

  • Working methods in detail.

  • Safety measures, Safe-Work-Analysis.

Experience the principles and working practice of gin poles.

Theoretical and practical training in the gin pole assembly and erection of lattice towers, and other applications.

Part I: For engineers, planners, project and site managers, technicians

  • Types of gin poles, terminology, different applications.

  • Calculation of forces and the choice of appropriate and tools and equipment. Absolute clarity about all load conditions and site situations.

  • Working methods in detail.

  • Tips and hints.

  • Case studies.

  • Project and site organization.

  • Safety measures, Safe-Work-Analysis.


Part II: For participants from Part I and foremen, riggers as well as other interested persons


  • Types of gin poles, terminology, different applications.

  • Required machines and equipment, anchoring, etc.

  • Working methods in detail.

  • Tips and hints.

  • Case studies.

  • Project and site organization.

  • Safety measures, Safe-Work-Analysis.

  • If desired (highly recommended): Practical gin pole exercises at ground level.

Manual calculation of induced voltages and currents:
A professional management approach of working in proximity of energized circuits and plants and a solid basis for Method Statements, SWA and H&S plans.
The participants will be able to make their own independent calculations and assessments rather than blindly trusting "one-click results" from software programs.

Brief summary of the training content:

    • Theoretical basics.

    • Geometric Mean Radius GMR of a multi-layer conductor with individual strand shape and its calculation, GMD, etc.

    • Complex earth depth and its calculation.

    • Capacitive induction, image conductors, capacitance of transmission lines.

    • Magnetic field induction, Carson's self- and mutual impedance.

    • Effect of shield wires.

    • Calculation examples: Precise calculation according to IEEETM 524 standard, Schnell/Clarke.
      "IEEE Guide for the installation of overhead Transmission Line Conductors",
      IEEE Std 524-2016 (Revision of IEEE Std 524-2003, April 2017).

    • Comparison of the results with and without shield wires or underground cables with neutral.
      Alternative calculations according to Clem, Dubanton, etc. and their limitations.

    • Case studies: Non parallel circuits, pipelines, underground and telecommunication cables.
