How do you model the bonding of cables (isolated, single and double bonded)?)

Power Equipment Models

There are various possibilities to "bond" the sheath / metallic screen (MSC). The bonding corresponds to the earthing of the sheath / MSC.

There are different bonding configurations for cables:


  • Isolated MSC: MSC is isolated on both sides
  • Single point bonding: MSC is grounded on one side only
  • Double bonding: MSC is grounded on both sides
  • Cross-bonding: MSC is grounded on both sides and transposed along the cable

The following project includes examples for detailed modelling of all the above bonding configurations, expect for cross-bonding. The detailed modelling of cross-bonding is demonstrated in the following FAQ:
