STUDY OF ELECTROMAGNETIC INTERFERENCE BETWEEN METAL DUCTS AND HIGH VOLTAGE LINES

When building or being built a metal infrastructure near the high voltage transmission lines, a problem known as AC interference occurs. Such interference may cause damage when:

 

  • Metal objects subject to an alternating electromagnetic field have an induced voltage and this interferes with their cathodic protection system, which jeopardizes the integrity of the personnel who build, operate or maintain.

  • Failures in the metallic elements can also be caused by corrosion and, consequently, this phenomenon reduces their useful life.

  • In short circuit failures or atmospheric discharges can generate in the buried structures, high potential for passage and contact that put personnel, equipment, machinery or even the integrity of the infrastructure at risk.

 

The main objective of the studies is to determine the possible risks by electromagnetic coupling, in order to issue the safety and technical recommendations to protect the personnel who work there, the transmission line infrastructure and the metal ducts in cross-over and parallel configurations.

 CATHODIC PROTECTION SYSTEMS FOR METAL STRUCTURES

 

Studies of cathodic protection are carried out to care for and / or increase the lifetime of marine and terrestrial pipes, such studies include:

 

 

  • Field survey, measurement of resistivities, ph, redox potential, determination of sulfate reducing bacteria.

  • Cathodic protection design with printed current and galvanic anodes.

  • Current requirement tests, guided waves, pipe wall thicknesses, CIS (Close Interval Survey, DCVG).

  • Commissioning and verification of systems.

  • Selection of anticorrosive coatings and application supervision.

 

The objective of the studies is based on performing the necessary work to care for and / or increase the useful life and structural safety of the metallic elements in the face of corrosion problems.
