A Day in the Life of your Overhead Optical Ground Wire (OPGW)

Date: Thursday, July 16, 2020

Time: 2:00pm - 3:00 pm EDT

Abstract:

Overhead Optical Ground Wire (OPGW) serves two main systems—i) power delivery and ii) telecommunications – by providing protection to overhead lines against lightning strikes, a return path to short circuit currents during system faults and a high capacity optical communications network. OPGW is an integral part of the power network system, and the expectations are high.

This webinar explores the life cycle of an OPGW: from initial concept and design, through installation, operation, maintenance and failure. Learn how to avoid common pitfalls with the help of testing – from Type Testing to qualify new designs, to custom failure investigations at end of life. Important considerations at each stage are investigated to help maximize the useful life of this critical infrastructure, and ensure safe, continuous and reliable operation.


Presenter:

Corrine Dimnik holds a B.Sc. of Mechanical-Materials Engineering from Queen’s University and is a registered Professional Engineer in the Province of Ontario.

Since joining Kinectrics in May 2008, Ms. Dimnik has been primarily involved with the mechanical and electrical testing of Transmission and Distribution Overhead Line Components. As a Principal Engineer, she specializes in the laboratory type testing of Optical Ground Wire (OPGW) cables, associated fiber optic hardware, and overhead electrical conductors.

She is the Vice Chair of the IEEE Fiber Optic Subcommittee. This subcommittee oversees the development and maintenance of industry standards related to OPGW cables, All-Dielectric Self Supporting (ADSS) Fiber Optic cables, Wrapped Fiber Optic cables and the associated hardware.

How Can I Better Assess the Condition of My Low Voltage Cables?

Date: Thursday, July 30, 2020

Time: 2:00pm - 3:00 pm EDT

Abstract:

Low voltage cables are mostly 600V cable designs supporting power, instrument, and control functions. Condition assessment of low voltage (LV) cables has its own challenges compared to medium and high voltage applications. Thermal conditions, chemical/wet environments, and in some applications, radiation/UV exposure are the principle stressors that contribute to aging. Voltage stresses normally do not contribute to LV aging. However, thermal aging is the dominant concern.

This webinar provides insights on the nature of low voltage cable aging, existing methods to assess material properties, and an overview of advanced electrical testing methods that can be deployed. Specifically, we will cover:
  • Overview of Low Voltage Cables
  • Degradation and Failure Mechanisms
  • Condition Assessment Methods and Challenges
  • Breakthrough Electrical Technologies for Condition Monitoring
  • Laboratory Analysis of Cables

Presenter:
