Stray Current Corrosion Monitoring System (SCCMS) Tested and certified system for monitoring and mitigating stray current damages for MRT & LRT stations in full compliance to BS EN 50122-2 International Standard and ISO 9001:2015 Certification Introduction Stray current as defined in BS EN 50122-2 as the part of a current which follow paths other than the intended paths and the consequence of stray current is that where it leaves a buried metal object, electrolytic corrosion will occur, frequently in highly localised areas and potentially leading to loss of material and damages This is clearly undesirable in the case of metallic pipes carrying gas and water, as leakage and/or rupture has obvious safety and/or operational risks to both the tramway and the general public. In the case of cables, particularly the older lead sheathed types, such loss occurs even more rapidly and can lead to breakdown of the (now) unprotected inner insulation of the cable.

IntroductionStray current as defined in BS EN 50122-2 as the part of a current which follow paths other than the intended paths and the consequence of stray current is that where it leaves a buried metal object, electrolytic corrosion will occur, frequently in highly localised areas and potentially leading to loss of material and damages
This is clearly undesirable in the case of metallic pipes carrying gas and water, as leakage and/or rupture has obvious safety and/or operational risks to both the tramway and the general public. In the case of cables, particularly the older lead sheathed types, such loss occurs even more rapidly and can lead to breakdown of the (now) unprotected inner insulation of the cable.
