Electromagnetic Induction from Power Lines to Metallic Third Party Assets

The coupling of electrical energy between a power system and neighbouring metallic third party infrastructure is complex and often misunderstood. In this presentation the general coupling mechanisms between power systems and proximate conductive third party infrastructure are explained. A detailed exploration of the coupling mechanisms associated with electromagnetic induction are provided from both a theoretical and practical perspective in an attempt to alleviate any such misconceptions within industry. The implications of these realisations to the present state of AS/NZS 4853 are discussed and the importance of the correct understanding and application of the theory is consolidated.
