Protective Relay Training - This 12-Hour live online instructor-led training course provides a comprehensive understanding of industrial, commercial and institutional power system protection. Relay technicians, system protection engineers, consultants, and engineers and technicians working in system protection should take this course.
Our Protective Relay Training course will benefit personnel of all levels of experience because it covers a range of complexity of relay schemes, methods of testing relays and of analyzing relay operations. We discuss system protection principles, measurement devices used for relaying, basic relay schemes used, and the most common schemes used in the field. This course provides professionals with real examples from actual system protection situations.
This Protective Relay Training course will cover relay theory and operation of modern digital types from two major North American relay manufacturers (GE Multilin and SEL), covering many types of functions such as phase, ground, negative sequence overcurrent, over and under voltage, over and under frequency, reverse power, distance and bus/transformer/line differential. Topics such as complete motor protection, fault current basics and application of fuses and circuit breakers / contactors in industrial and distribution substations, will also be covered.
Engineers who need a comprehensive understanding of the challenges and solutions for protecting electrical power systems should attend this course.
The Protective Relay Training course provides basic guidelines for relay application and settings calculation. It also reviews basic power system concepts and describes instrument transformers. This training course is designed for technicians, operators, maintenance personnel and engineers who need a comprehensive understanding of the challenges and solutions for protecting industrial power systems. This training course provides guidelines how to download and install North American relay manufacturers software packages, guidelines how to establish communication between laptop and relay as well as basic relay logic programing examples. Course provides guidelines for the relay protection application, principles and setting calculation and an overview of the principals of the relaying protection for motors, transformers, medium voltage cables, feeders, buses, generators, transmission and distribution lines, breaker failure and capacitor banks. This training course also reviews basic power system concepts and current and voltage instrument transformers. Protection requirements for industrial plants, cogeneration, and interconnection with the utility power system are explained in detail. This course covers the subject of power system protection from a practical perspective, and includes important functional aspects such as testing and coordination of protection systems. This course is designed for individuals who are involved with industries and utilities which depend on proper system protection for operational efficiency and minimizing damage to equipment.
A properly designed protection system has downstream devices (breakers/fuses/relays) should activating before upstream devices. This minimizes the portion of the system affected by a fault or other disturbance. At the substation level, feeder breakers should trip before the main. Likewise, downstream panel breakers should trip before the substation feeder supplying the panel.
Power System Protection And Coordination of various electrical equipment and apparatus requires a good understanding of phase and ground short circuit currents, detection, and safe clearing of the faulted equipment.
Large or small, each and every industrial, commercial and institutional organization needs to understand how to protect their investment in their electric power systems. To do this properly, companies need to know how to perform an electrical protection analysis of all the parts of their power system: such as analyse fault data, come up with protection settings, then get all of the components of their plant to be controlled by the operators who are responsible for integrating their power system into communication and data acquisition modes.
Students will be learn the essentials of electrical protection design, relay coordination, and fusing fundamentals, breaker fundamentals. Students will be provided with an understanding of digital protective relaying, as we go through practical examples of generator, feeder, motor, and transformer electrical protection.
Note: It will be beneficial if students will have own laptop.
