Relay Training Center Seminar
(the mathematics behind protective relay testing).
Conducted at your training site, your training cost per student goes way down.
Our instructor has many years experience as a protective relay technician and knows what your technicians need to better understand their job.
Class Objective:
To teach beginning relay technicians that the mathematics behind protective relay testing is well within their grasp. That the trigonometry and the AC-DC theory that they already know is the backbone of the technical aspects of their job.
Pre-requisites:
Students should already have a background knowledge of trigonometry, AC-DC theory and the purpose of power system equipment (transformers, circuit breakers, revenue & indicating meters, protective relays, PT's, CT's, etc.). It is generally suggested that perhaps this course is too advanced for a first year apprentice. But, certainly a must before graduation !
While this course is too basic for engineers, it is ideal for journey-level technicians who need an understanding of why they test relays the way that they do. It is also perfect for journey-level training staff that are trying to assemble an apprentice training program of their own.
While it helps the students if they have at least worked on a protective relay, it will also be invaluable to the students that have only seen relays and been told of their purpose in a power system.
Course Outline:
The course particulars can be worked out to meet your specific needs.
The typical course consists of three 8-hour sessions. (However, let's talk about your needs.)
The seminar covers many of the topics presented in Relay Training Center software and addresses:
How to calculate:
apparent power, true power and reactive power
load angle and power factor
power per revenue meter revolution
mA output for given three-phase power input to watt/var transducers
phase-to-phase voltage from any two given phase-to-neutral voltages
positive sequence voltage and current
negative sequence voltage and current
zero sequence voltage and current
radial-line fault distance (impedance)
How to convert:
primary impedance values to secondary impedance values
secondary impedance values to primary impedance values
polar coordinates to rectangular coordinates
rectangular coordinates to polar coordinates
Schweitzer relay event reports to phasor values (and diagrams)
Along the way, subjects that are discussed include:
directional relays
typical relay schemes
distance relaying
zones of coverage
permissive schemes
R-X diagram
phasor diagram
Check out this seminar test example. The instructor presents material that covers the calculations needed to complete this test. Use the test as a method to determine if this seminar is right for you. If you never have any of these problems then this seminar would simply waste your time. If you or your people need to know how to perform these calculations then contact us. It's never too late to learn !
