COURSE OUTLINE

WELCOME BY RECTIFIER INSTRUCTOR
The Rectifier Course outline and objectives are discussed.

SLIDE PRESENTATION
Rectifiers and their application, styles, types, features, and typical field installations.

TECHNICAL SESSION
Theory and operation, Ohm's Law, basic cathodic protection, reference voltages, potentials, and IR free definition. Demonstrate working model of a CP system and the relationship to a rectifier.

RECTIFIER COMPONENT DESIGN AND OPERATION
Transformers, silicon and selenium rectifiers, surge protection, breakers, fuses, lightning protection, etc. Maintenance and maximum operating temperatures of each major component.

SHUNTS
Shunts and shunt readings and factors.

SPECIAL PURPOSE RECTIFIERS AND THEIR USE
Oil-immersed units, three phase, constant current, potential control, and multiple circuits. Demonstration of constant current and potential control units, and remote monitoring.

WIRING DIAGRAMS AND SCHEMATICS
Typical types.

RECTIFIER AND CP SYSTEM EFFICIENCIES AND IMPROVEMENTS
Conventional readings vs. watt-hour readings, power factors, and methods of increasing rectifier output ratings.

GENERAL RECTIFIER MAINTENANCE AND REPAIRS
Test instrument use and operation, transformer and stack replacements, determining cable lead polarity, cable breaks, series and parallel operation, and interrupter operation.

TROUBLESHOOTING
Standard units vs. special purpose, useful hints, and troubleshooting aids.

HANDS-ON TROUBLESHOOTING
Analyze various problems and perform repairs.
(Bring your own multimeter for hands-on)

*THIS IS NOT AN AMPP SPONSORED RECTIFIER TEST*

PRE-REQUISITES
An understanding of basic electricity and a minimum 240 hours of actual CP testing related work experience are seriously recommended.

WHO SHOULD ATTEND
Cathodic protection field personnel, technicians, and those desiring knowledge of rectifiers should attend this course.

REGISTRATION FEE
The fee for the Rectifier Course is $495 and includes course manual, 3 lunches, continuous refreshments, and 2 evening social hours.

EXAM
An exam that includes a written and practical test will be given.
