6T - AC Motor Protection$90.00Learn MoreThere 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.

4T - Generator Protection$60.00Learn MoreThis course was made as a reference guide for generator protection. Protection relays that are described in this course are applicable to one or more generator protection schemes. There are a number of protection relay types and those are used for protection against a wide variety of conditions. These protection relays protect the generator or prime mover from damage. Also they are used for protection of the external power system or the processes it supplies. The basic principles that are described in this course apply equally to individual relays and to multifunction numeric relays. The protection engineer needs to balance the expense of using a particular relay against the consequences of losing a generator. The complete loss of a generator may not be catastrophic in the case it represents a small part of the investment in an installation. Nevertheless, the impact on service reliability and upset to loads has to be taken into consideration. Damage and loss of product in continuous processes can represent the ultimate concern rather than the generator unit. Therefore, there is no typical protection solution based on the power rating.
This course is suitable for engineers with a desire to understand the fundamentals of generator protection. Presented details cover issues related to generator protection technical implementation. Upon successful completion engineers will be able to address key generator protection concepts, terms and characteristics.

3T-Industrial System Protection$50.00Learn MoreDescription:
Development of industrial and commercial electrical power systems has also introduced the requirements for their improved reliability. The possible outage time costs have also dramatically increased. The introduction of automation systems into industry and commerce requires application of advanced power system automation in order to enhance overall reliability and efficiency. Careful attention has to be given to the protection and control of industrial electrical supply systems.
Many technologies that have been developed for EHV electrical systems may be used in lower voltage systems but usually on a reduced scale. Nevertheless, industrial electrical systems have many particular issues that need special attention and the development of custom solutions.
This course is suitable for electrical engineers with a desire to understand protection fundamentals that are applicable to industrial systems. Presented details cover protection of different equipment such as motors, feeders and transformers. Description of MCBs, MCCBs, fuses, different circuit breaker technologies and relays is also provided. Upon successful completion engineers will be able to address industrial system protection basics is terms of available protection technologies, methods, protection arrangements and their application to typical design configurations.

3T - Principles of HVDC Transmission$50.00Learn MoreThe 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.

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

3T - Distance Protection$50.00Learn MoreSince 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.

2T - Wind Energy Project Analysis$30.00Learn MoreIn addition to large scale applications, there are a number of other applications for wind turbines, such as medium scale applications on isolated-grids and off-grid uses for pumping water and providing smaller amounts of electricity for stand-alone battery charging applications.

3T - Introduction to Motor Starting Analysis$50.00Learn MoreThe 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.
