  1. 3T - Principles of HVDC Transmission
    $50.00

    The question that is frequently discussed is: “Why does anyone want to use D.C. transmission?” One reply is that electric losses are lower, but this is not true. Amount of losses is determined by the rating and size of chosen conductors. Both D.C. and A.C. conductors, either as transmission circuits or submarine cables can generate lower power losses but at increased cost since the bigger cross-sectional conductors will typically lead to lower power losses but will unfortunately cost more.

  2. 3T - Gas Insulated Substation Definitions and Basics
    $50.00

    When determining between AIS or GIS technology, some elements alone, for example aesthetics, may be an overcoming impact on a user’s conclusion. Nevertheless, most of the time the best conclusion asks for assessing many elements and soliciting input data from many sections within an investor’s organization. It is also critical to note that the optimal substation arrangement may not be solely AIS or GIS. Sometimes a mix of the two (i.e., hybrid or mixed-technology) might be the best arrangement. Typically, most of the factors will prefer GIS technology, but it is the value or importance given to the considerations that decides if the return on investment is justifiable to choose GIS over AIS technology. Consideration that can be measured should be assigned importance weights based on the user’s needs.

  3. 2T - Power System Transient Stability Study Fundamentals
    $30.00

    The ability of a power system, containing two or more synchronous machines, to continue to operate after a change occurs on the system is a measure of its stability. The stability problem takes two forms: steady-state and transient.

  4. 3T - Distance Protection
    $50.00

    Since the impedance of a transmission circuit is relative to its length, for distance measure it is suitable to use a relay able to measure the impedance of a circuit up to a present point (the reach point). Such a protection relay is known as a distance protection relay and is made to function only for faults happening between the protection relay location and the chosen reach point, therefore providing discrimination for short circuits that may happen in different line portions.

  5. 3T - Introduction to Motor Starting Analysis
    $50.00

    The starting current of most AC motors is several times normal full load current. Both synchronous and induction motors can draw five to ten times full load current when starting them across the line. Motor-starting torque varies directly as the square of the applied voltage. If the terminal voltage drop is excessive, the motor may not have enough starting torque to accelerate up to running speed. Running motors may stall from excessive voltage drops, or under-voltage relays may operate. In addition, if the motors are started frequently, the voltage dip at the source may cause objectionable flicker in the lighting system.

  8. 6T - AC Motor Protection
    $90.00

    There is a wide range of AC motors since they can be used in numerous applications. AC motors need to be protected but protection selection usually does not depend on the motor and load type. This selection is based on the fundamental AC motor operation processes. There are crucial differences between the protection of induction motors and synchronous motors. Motor operation characteristics have to be particularly considered when applying selected protection. This approach is more important for the motors than for any other power system element.

    For example, the starting and stalling currents/times have to be known and taken into account when using overload protection. Also the thermal withstand of the AC motor has to be precisely defined under balanced and unbalanced loading conditions. The conditions for which AC motor protection is needed can be separated into two main groups: imposed external conditions and internal short circuits.

    This course is suitable for electrical engineers with a desire to understand the fundamentals of AC motor protection. Presented details cover issues related to protection against external and internal motor faults. Upon successful completion engineers will be able to address AC motor protection terminology and concepts and techniques that are used for overload, single phasing, under-voltages, unbalanced supply and reverse phase sequence faults.

  9. 3T-Unit Protection of Feeders
    $50.00

    The graded overcurrent protection design, though quite simple, do not meet all the protection demands of an electrical power system. Application issues are experienced for two reasons: firstly, acceptable grading cannot be accomplished for a complex electrical system, and secondly, the protection adjustments may lead to maximum operating times that are excessive and cannot stop faults. 

    These issues are directed to the unit protection concept. This concept means that parts of the electrical system are separately protected without reference to other parts of the electrical system. One unit protection concept is widely known as ‘Differential Protection’. Foundation of this principle is to detect the difference in currents between the incoming and outgoing terminals of the protected element. Other unit protection concepts can be based on directional comparison, distance tele-protection arrangements or phase comparison unit protection. 

    This course is suitable for electrical engineers with a desire to understand the fundamentals of feeder unit protection. Presented details cover basic unit protection concepts and their particular applications to high voltage feeders. Upon successful completion engineers will be able to address basic feeder unit protection terminology, concepts, applications and arrangements.
