Stray current investigation


The effects of stray currents from direct current (DC) sytems (railways, tramways, mines, HVDC transmission, cathodic protection, etc.) are so well known that investigation and implementation of remedial measures is an integral of CP projects. However, some CP systems may face unique problems which require more detailed and sophisticated investigation.


In most cases, it is not until some damage has already been caused that analysis is made of the effects of stray currents and the remedial measures needed to solve the problem. We can also provide risk assessment and mitigation planning for proposed new CP systems so that any necessary remedial measures can be implemented in advance. This helps avoid delays which often arise when interfering systems are being operated by different owners.
