HVDC Transient and Stray Current Influence on Pipelines
High Voltage Direct Current (HVDC) transmission systems, particularly during faults and switching events, can generate rapid changes in current and voltage. These transients may induce voltages and currents in nearby pipelines, potentially compromising safety, coating integrity, and corrosion protection systems.
At ERCS, we conduct comprehensive HVDC transient studies that include:
-
System Dynamics Modeling – Simulating HVDC line faults, pole-to-ground events, and converter operations to understand transient behavior.
-
Electromagnetic Coupling Assessment – Evaluating induced voltages and currents on pipelines considering soil resistivity, proximity, and pipeline characteristics.
-
Compliance Evaluation – Comparing results against international safety and reliability standards (IEEE, IEC, NACE).
-
Mitigation Design – Recommending practical measures such as optimized grounding, decoupling devices, or coating enhancements to control induced effects.
These studies provide a reliable basis for ensuring safe, compliant, and long-term operation of both HVDC systems and parallel pipelines.
AC/DC Interference On Pipeline, Railway or Communication Cables
When AC transmission lines or DC systems are routed close to pipelines, telecommunication cables, or railways, they can introduce electrical interference into these metallic infrastructures. Such interference can compromise safety, reliability, and asset integrity if not properly assessed and mitigated. The primary mechanisms of interference include:
-
Electromagnetic Induction – Alternating currents in power lines generate electromagnetic fields that can induce voltages on nearby metallic structures such as pipelines, cables, or railway tracks.
-
Conduction (Fault Current Transfer) – During fault conditions, such as line-to-ground faults, large fault currents flow into the soil and may be transferred to adjacent buried conductors, potentially exposing them to hazardous voltages.
-
Electrostatic Coupling – High-voltage lines can cause charge accumulation on nearby metallic systems, which may lead to unwanted voltage potentials.
If left unaddressed, these interferences can lead to AC-induced corrosion in pipelines, degradation of protective coatings, unsafe step and touch voltages, and operational hazards for connected assets.
A systematic study and mitigation design—covering modeling, field measurements, and compliance with international safety standards—is essential to ensure both system performance and long-term asset protection.
Earthing & Grounding Studies for Substations, Solar, and Wind Farms
Earthing and grounding are fundamental practices in electrical power systems, essential for ensuring safety, reliability, and regulatory compliance. Although the terms are often used interchangeably, they serve distinct but complementary functions:
-
Earthing – Connecting exposed conductive parts of electrical equipment directly to the earth. This ensures that, in the event of insulation failure or abnormal voltage rise, hazardous potentials are safely dissipated, protecting both people and equipment from electric shock.
-
Grounding – Providing a deliberate, low-resistance path for fault currents to flow into the earth. This minimizes equipment damage, enables protective devices to operate effectively, and enhances overall system reliability.
Together, earthing and grounding help maintain system stability, effective fault clearance, and protection against electrical hazards such as step and touch voltages, lightning surges, and transient overvoltages.
At ERCS, we specialize in earthing and grounding studies for electrical substations, solar PV plants, and wind farms. Our services address critical aspects such as fault current dissipation, personnel safety, lightning protection, and reliable system performance. Studies are conducted in line with IEEE, IEC, and CIGRÉ standards, using CDEGS and associated tools to model fault conditions and assess grounding performance.
Where required, we also provide optimized mitigation solutions—including grounding system enhancements, safety improvements, and cost-effective design adjustments—ensuring both compliance and long-term reliability of your electrical infrastructure.
