Our customers can rely on our extensive and up-to-date knowledge of our experts about industrial (up to 100kA) , power transformers (up to 1000kV AC, 800kV DC) and network studies, solid organization with very advanced simulation tools and laboratories, independence.

With network studies we can support our customer in order to: improve protections by predicting interaction between transformers and network increase the reliability of your plant minimize costs Investigate a failure (analysis) and develop mitigation actions

We can provide:

Electromagnetic Transient Studies

• Insulation coordination studies

  • Lightning overvoltages

  • Switching overvoltages

  • Temporary overvoltages

• Ferroresonance investigations

• RC-filters dimensioning

Power System Studies

• Extensive power system studies are required to confirm that the proposed electrical systems for new/revamped industrial plants satisfy stringent design requirements.

• Load-flow, short-circuit and transient-stability studies typically undertaken of such a systems

Power Quality Analysis

• Calculation of PQ indexes
  (Harmonics, Rapid Voltage Changes, Flicker, Unbalance, Dips and Short interruptions)

• Analysis of mitigation alternatives

• Technical Specifications of mitigation equipment

• Assessment of Power Quality indexes

Training Courses

Weidmann can provide customized training courses about:

• Power Quality issues (flicker, harmonics, dips, etc.)

• Electromagnetic Transients (lightning, switching and temporary overvoltages, ferroresonance, etc.)

• How to use simulation software for Network Studies applications
