AC Voltage Mitigation
When your pipeline shares a right of way with high-voltage power lines, the electromagnetic field on the power lines can induce unwanted voltage onto the pipeline. This steady-state AC voltage is a safety hazard for personnel and can contribute to corrosion problems. In order to mitigate this voltage, you require an effective grounding path that will continue to isolate DC voltage for cathodic protection.
Dairyland decouplers such as the SSD, PCR and PCRX, will provide you with an effective grounding path that mitigates induced AC, while simultaneously maintaining DC isolation. This is possible due to the nature of a Dairyland decoupler which provides a low resistance to AC and high resistance to DC simultaneously. As a result, your CP system will continue to work efficiently and personnel will be safe from unwanted AC interference.
