Transmission Line Evaluation

EMF, EMI/EMC, and Technical Review for Electric Transmission Projects

ELEXANA provides independent technical support for electric transmission-line projects, including EMF/RF assessments, magnetic-field modeling reviews, right-of-way exposure evaluations, EMI/EMC concerns near sensitive equipment, and technical reporting for facilities, municipalities, property owners, developers, counsel, and project stakeholders.

Our work helps clients understand how proposed or existing transmission infrastructure may affect electromagnetic conditions, equipment reliability, sensitive facilities, and nearby properties.

Independent Transmission-Line Technical Review

Electric transmission projects can raise complex questions involving magnetic fields, electric fields, induced current, right-of-way conditions, equipment interference, sensitive facilities, and public or workplace concerns. ELEXANA helps clients evaluate these issues through calibrated measurement, modeling support, document review, and practical electromagnetic engineering interpretation.

In New York, this may include technical support related to Article VIII or legacy Article VII transmission matters. In other states, ELEXANA can support comparable public-utility, environmental, transmission-siting, right-of-way, and certificate-review processes.

What We Evaluate

ELEXANA can support transmission-line review through:

  • Review of applicant EMF and technical filings

  • Independent magnetic-field modeling and sensitivity analysis

  • Right-of-way and edge-of-ROW exposure evaluation

  • EMF/RF field assessment for nearby properties and facilities

  • Review of transmission-line geometry, conductor height, phasing, current assumptions, and co-located lines

  • Baseline and post-construction field measurements where appropriate

  • EMI/EMC evaluation near sensitive equipment

  • Induced-current and coupling concern screening

  • Technical questions for applicants, counsel, municipalities, or project teams

  • Independent technical memoranda and reports

Sensitive Facilities and Equipment

Transmission-line evaluation is not limited to general EMF concerns. ELEXANA also reviews possible electromagnetic compatibility issues near sensitive environments and equipment, including:

  • Hospitals and medical facilities

  • Laboratories and research facilities

  • Data centers and mission-critical facilities

  • Semiconductor and precision manufacturing sites

  • Industrial control systems

  • Robotics and automation facilities

  • Communication systems and security infrastructure

  • Sensitive instrumentation and measurement equipment

  • Workplaces where employees may use implanted or wearable medical electronics

Our goal is to identify whether electromagnetic conditions could contribute to interference, malfunction, measurement noise, operational instability, or reliability concerns.

Magnetic-Field Modeling and Review

ELEXANA can review or independently model magnetic-field conditions associated with proposed or existing transmission lines. Modeling may include:

  • Magnetic field versus distance from centerline

  • Edge-of-right-of-way values

  • Specific receptor locations

  • Normal-load and peak-load cases

  • Alternative conductor phasing

  • Conductor height and sag sensitivity

  • Co-located transmission-line contributions

  • Before-and-after comparisons for line upgrades

  • Monte Carlo or sensitivity analysis where useful

This modeling can help clients better understand how transmission-line configuration, loading, geometry, and distance affect real-world field conditions.

Field Measurements

Where appropriate, ELEXANA can perform field measurements to document existing or post-construction electromagnetic conditions. Measurement work may include:

  • 60 Hz magnetic-field surveys

  • Electric-field measurements where relevant

  • RF background surveys

  • Power-quality observations

  • Measurements near sensitive equipment or facilities

  • Baseline documentation before project construction or energization

  • Post-construction verification measurements

Field measurements can be useful when existing infrastructure is present, when a project involves upgrades, or when sensitive equipment, facilities, or property-specific concerns require real-world verification.

EMI/EMC and Equipment Reliability Review

ELEXANA can evaluate whether transmission infrastructure, nearby electrical systems, or associated facilities may create electromagnetic compatibility concerns for equipment or operations.

This may include review of:

  • Medical equipment reliability

  • Laboratory instrumentation sensitivity

  • Data-center equipment concerns

  • Industrial controls and PLCs

  • Robotics and automation systems

  • Communication and security systems

  • Low-voltage wiring and control circuits

  • Sensitive measurement systems

  • Potential induced current or coupling effects

ELEXANA provides practical recommendations for further investigation, mitigation, equipment relocation, shielding, grounding, bonding, filtering, or monitoring where appropriate.

Who We Support

ELEXANA can assist:

  • Municipalities

  • Property owners

  • Commercial facilities

  • Hospitals and healthcare systems

  • Laboratories and universities

  • Data centers

  • Industrial facilities

  • Developers

  • Law firms and consultants

  • Community stakeholders

  • Project teams seeking independent technical review

Deliverables

Depending on the scope, ELEXANA can provide:

  • Initial technical review memos

  • EMF / magnetic-field modeling summaries

  • Measurement reports

  • Right-of-way exposure evaluations

  • EMI/EMC concern assessments

  • Technical questions for applicants or agencies

  • Independent stakeholder reports

  • Exhibits, charts, and summaries for meetings or review processes

  • Recommendations for additional testing, modeling, or mitigation

Article VIII and Transmission Siting Support

For New York transmission projects, ELEXANA can support technical review related to Article VIII electric-transmission matters, including applicant filing review, magnetic-field modeling, right-of-way assessment, EMF/RF concerns, and EMI/EMC evaluation near sensitive facilities.

For projects outside New York, ELEXANA can provide comparable technical support for state public-utility, environmental, transmission-siting, right-of-way, and certificate-review processes.

Professional Engineering Boundary

ELEXANA provides electromagnetic measurement, modeling support, EMI/EMC review, technical analysis, and independent reporting. Where sealed professional engineering services, design certification, regulatory sign-off, or construction-related engineering approval is required, ELEXANA works with or recommends appropriately licensed Professional Engineers.

ELEXANA does not provide legal advice, permit approvals, or public health determinations.
