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...
MOTOR SINGLE PHASING BASIC DEFINITION AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 10, 2012A 3-phase motor can be subjected to a situation referred to as “single phasing.” Single phasing means one phase is open—somewhere. The current values shown in the figures are for a “pure” single phasing condition with one motor only in...
REPULSION START INDUCTION RUN MOTORS BASIC DEFINITION AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 10, 2012The repulsion-induction motor starts on one principle of operation and, when almost up to speed, changes over to another type of operation. Very high twisting forces are produced during starting by the repulsion between the magnetic pole in the ar...
MOTOR MAGNETIC CORE LOSSES BASICS AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 10, 2012Magnetic core losses consist of the eddy current and hysteresis losses, including the surface losses, in the magnetic structure of the motor. A number of factors influence these losses: 1. The flux density in the magnetic structure is a major fact...
WORLD'S ONLY FERRARI-ENDORSED MOTORBIKE UP FOR AUCTION by Trivia Galore on May 5, 2012Get ready for a one of kind opportunity as the one and only Ferrari-endorsed motorcycle ever made is going to be auctioned pretty soon. The bike has been crafted as a tribute to the man that founded the brand, Enzo Ferrari, by a British engineer call...
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...
