Fiber Optics in High Voltage Transmission Environments EE 566 October 8, 2003 By: Jason Jones

Slide 2

My Reason for Choosing This Topic… Find a Combination Between Fiber Optics and Power Engineering This is taking a gander at Fiber Optics in an option industry Fig. 1 Fig. 2

Slide 3

Overview Basics of fiber optic and electrical transmission lines Different employments of fiber optic link in the transmission matrix framework Employment alternatives Conclusion/rundown

Slide 4

Can high voltage power be sent through fiber optics link? No definitive confirmation or research has demonstrated that it is conceivable. Just the utilization of converters, still not viable for long separations and high voltage.

Slide 5

Why utilize fiber optics with transmission lines ? Detecting and recognition of electrical shortcomings and failure(i.e –Supervisory Control and Data Acquisition Systems – S.C.A.D.A) Can be utilized as a nonpartisan or ground. No EMC/EMI issues. Correspondence amongst plants and substations Extensive ROW (Right Of Way). The cost focal points of existing ROW makes utilities alluring line-renting accomplices for some interchanges transporters.

Slide 6

Fiber optic links Transmits light (photons) Primarily for correspondences Electric links Transmits power (electrons) Primarily to power electrical gadgets Combination of Two Different Concepts

Slide 7

Most usually utilized Fiber Optic All Dielectric Self Supporting (ADSS) Wrap sort Optical Ground Wire (OPGW)

Slide 8

Details of ADSS Cables High fiber check Cheaper than OPGW Installed along electrical transmission lines Fig. 3

Slide 9

Details of the OPGW is a composite wire which serves as an ordinary overhead ground wire, with the additional advantage of giving high-limit and solid fiber optic correspondence. Fig. 4

Slide 10

Common Problems Contamination – manure, pesticides, deplete, discharges, salt haze. Must be settled on the plan level, troublesome due to high voltage outline prerequisites Space Potential – Electrical potential instigated on fiber optic links Dry Band Arcing – Caused by the prompted current amid wet conditions

Slide 11

Space Potential Induced voltages can be in the many kV extend. Causes dry-band voltages and streams. Causes immense and effective electric fields. Fig. 5

Slide 12

Dry Band Arcing Caused by Space Potential and recurrence of current in the link. Accurse in wet situations Because of high instigated voltage, current can be as low as 1.5mA. Fig. 6

Slide 13

Employment Options Phillips Corning Fiber Planners The Furukawa Electric Co. Most power service organizations (i.e. National Grid, Alliant Energy, Duke Energy)

Slide 14

Conclusion/Summary Many research conceivable outcomes. Exceptionally fascinating vocation. Great possibility of turning into a specialist. High Voltage – BE CAREFUL
