Since its foundation, SGK has been dealing with stray current problems. This topic is still highly relevant today Since its foundation, SGK has been dealing with stray current problems. This topic is still highly relevant today and our know-how is internationally recognised. Specifically, the following work is carried out:

• Examination of stray current protection measures
• Measurement of the rail insulation
• Checking the earthing situation with regard to the risk of corrosion
• Fault location in earthing systems
• Support in the project planning of protective measures

The SGK's broad knowledge of materials technology often enables useful additions, e.g. investigations on entire components with different material combinations and corrosion protection systems.
