Protection against dangerous touch voltage and elimination of stray currents
A stray current (interference) is an electric current which goes through other metallic structures than the intended conductors. Balslev performs control and measurements plus initiate other measures to eliminate dangerous touch voltages and stray currents in connection with electrified railways, pipeline systems and high voltage systems etc.
Avoid the risk of corrosion
Large infrastructural systems such as electrified railways can pose a risk of dangerous touch voltage and/or stray currents on nearby electrical conductive structures. This applies to e.g. railway stations plus other large infrastructural systems like district heating pipes plus oil and gas pipelines. In these areas, stray currents can lead to corrosion of the pipelines - and in the worst case cause danger for people and installations.
Our electrical engineers possess vast experience in dealing with such undesired voltages and currents, and advise our customers how to avoid or reduce these. In co-operation with HMN Natural gas (formerly HNG) we have conducted a comprehensive analysis and measurements to detect the existance of stray current in natural gas pipelines. Among other things we perform measurements to determine if stray currents are present and to find their origins. Our services typically include:
- Pipeline integrity calculations
- Conceptual and basic design
- Detail design and tender materials
- Supervision
- Commissioning, control measurements and reporting.
