SYNCHRONOUS GENERATOR LOSS OF EXCITATION PROTECTION BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 20, 2012A loss-of-excitation on a generator occurs when the field current is no longer supplied. This situation can be triggered by a variety of circumstances and the following situation will then develop: 1. When the field supply is removed, the generator...
SYNCHRONOUS GENERATOR ANTI MOTORING PROTECTION BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 20, 2012A number of situations exist where a generator could be driven as a motor. Anti-motoring protection will more specifically apply in situations where the prime-mover supply is removed for a generator supplying a network at synchronous speed with the...
TRENDS IN POWER SUPPLY BASICS AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 10, 2012As costs of electronics decline, the power supply becomes a larger fraction of system cost and design effort. One major manufacturer estimates that power supply cost will soon reach 50% of the total cost of a typical electronic product such as a cord...
ENERGY MANAGEMENT BASICS AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 28, 2012Generation control and ED minimize the current cost of energy production and transmission within the range of available controls. Energy management is a supervisory layer responsible for economically scheduling production and transmission on a global...
ECONOMIC DISPACTH OF POWER GENERATION BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 14, 2012POWER GENERATION ECONOMIC DISPATCH BASIC INFORMATION What Is Power Generation Dispatch Economy? Since all the generating units that are online have different costs of generation, it is necessary to find the generation levels of each of these uni...
ROTATING MACHINES CORONA PROBE TESTS BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 3, 2012ROTATING MACHINES CORONA PROBE TESTS BASIC INFORMATION What Are Corona Probe Tests For Rotating Machines? The corona-probe test is intended to be an indicator and locator of unusual ionization about the insulation structure. This test is sensiti...
CONDITIONS THAT WILL REDUCE THE SERVICE LIFE OF ROTATING MACHINES by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 3, 2012ROTATING MACHINES SERVICE LIFE REDUCTION CONDITIONS What Are Conditions That Reduces Service Life Of Rotating Machines? As has been stated, electrical machines and their insulation systems are subjected to mechanical, electrical, and thermal st...
ROTATING MACHINES STATOR WINDING OVER VOLTAGE TEST BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 3, 2012ROTATING MACHINES STATOR WINDING OVER VOLTAGE TEST BASIC INFORMATION What Is Over Voltage Test Of Stator Winding? Overvoltage Test. Overvoltage tests are used to obtain assurance concerning the minimum strength of the insulation. Such tests are...
MOTORS AND GENERATORS CORE LOSS AND FRICTION AND WINDAGE LOSS (NO LOAD TEST) by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Apr 3, 2012MOTORS AND GENERATORS CORE LOSS AND FRICTION AND WINDAGE LOSS BASICS What Are The Core and Friction & Windage Losses of Motors and Generators? The test is made by running the machine as a motor at rated voltage and frequency without connecte...
WIND ELECTRIC POWER APPLICATIONS BASIC AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Jan 6, 2012APPLICATIONS OF WIND ELECTRIC POWER When We Do We Used Wind Electrical Power? There are perhaps four distinct categories of wind power which should be discussed. These are 1. small, non-grid connected 2. small, grid connected 3. large, non-grid conn...
