Protective Relaying (PR)

Self Study Unit 1

This course explores the components of an electric power system from production to consumption. It covers the fundamental principles of electricity (voltage, current, power, resistance, impedance) and introduces trigonometry and basic vectors that are used in calculating AC voltages and currents. Participants learn the basic math skills needed to perform calculations used in the industry. This course uses a TI-30 calculator and the text shows actual calculator strokes to work example problems. There are five chapter tests to complete for this unit. Students will be required to pass each chapter test with a 70 or above in order to continue to the next chapter.

Self Study Unit 2

Building on Unit 1, the student is taken through the principals of circuit calculations that include inductors and capacitors. It starts with single-phase circuits and then moves into three-phase circuit analysis. The material also covers items such as the relationships of voltages in currents across different transformer configurations, AC power calculations and metering fundamentals. Each section of this course has an exam that is graded by TVPPA. This unit is made up of 10 lessons covering the fundamentals of alternating currents. Students will be required to pass each chapter test with a 70 or above in order to continue to the next chapter. Completion of Substation Maintenance Unit 1 – Basic Math and Electricity is required for enrollment.

PR Self Study Unit 3

This course contains detailed study of the different types of protective relays, the application of those relays to specific configurations and a deep-dive into the criticality of the timing relationships between various types of devices. The student will be looking at the tools used to set microprocessor relays, as well as the aspects of the cybersecurity of the communication wide area and local area networks. An overview of test equipment and testing procedures is integrated into this specialist certification.

PR Lab

This lab covers the following: basic relay co-ordination, zones of protection, relay testing and programming of Schweitzer 351, standard electromechanical relay, dispatcher training, operations training for how to read one lines, primary maps, coordination of fuses, OCRs, sectionalizers and S&C change over devices.
