Avoid AC corrosion, limit overvoltage, protect pipelines and people

The smart decoupling device VCSD 40 IP65 (Voltage Controlled Smart Decoupling Device) protects pipelines and people from long-duration, temporary and transient overvoltages. Long-duration AC voltages are limited to a preset value by the voltage-controlled short-circuiter of the decoupling device.

The advantage: This does not negatively affect the desired cathodic protection potential (DC potential) of the pipeline.
