COURSE OVERVIEW

 This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

Utilities are required to provide power to their customers within a specific range of voltage. Voltages that are outside of that range may damage equipment or cause it to operate inefficiently. For example, voltage that is significantly lower than the desired range may cause lights to dim and motors to burn out. 

 

Voltage that is significantly higher may cause lights or appliances to fail prematurely. In an ideal AC power system, the voltage and frequency at every supply point would be constant and free of harmonics, and the power factor would be unity. In particular, these parameters would be independent of the size and characteristics of consumers' load. 

 

In an ideal system, each load could be designed for optimum performance at the given supply voltage, rather than for merely adequate performance over an unpredictable range of voltage.  

Moreover, there could be no interference between different loads as a result of variations in the current taken by each one. During this course, participants will be able to describe why voltage regulation is needed in a transmission and distribution system, explain the effect of raising voltage at the substation bus, identify the main components of automatic voltage regulator, identify the principle of operation of the auto re-closure, explain the typical locations of auto-re-closure on the distribution system, identify the advantages of installing auto-re-closures on the distribution system, describe how a sectionalize operates in a re-closure circuit and describe how an automatic voltage regulator adjusts voltage. 

 

This course is designed to provide participants with a detailed and up-to-date overview of automatic voltage regulator (AVR) operation and maintenance. It covers the AVR dynamics, AVR communication systems and interface-hardware and software, the construction and function; the auto reclosure and voltage regulators operation procedures; the circuit breakers gas turbine combustion; and the voltage regulators inspection and solid fuels control gasification. 

 

During this interactive course, participants will learn the operating mechanisms for auto re-closers; the regulator replacement; the trouble analysis procedure, common trouble and remedial actions; the supervisory-local-remote control circuits of circuit breakers; the secondary wiring of control circuit; and the commissioning, operation, troubleshooting and maintenance of AVR.
