Power System Fault Analysis 2.0 Introduction The fault analysis of a power system is required in order to provide information for the selection of switchgear‚ setting of relays and stability of system operation. A power system is not static but changes during operation (switching on or off of generators and transmission lines) and during planning (addition of generators and transmission lines). Thus fault studies need to be routinely performed by utility engineers (such as in the TNB). Faults

Abstract In our experiment‚ we analysed three-phase balanced or unbalanced circuits by using PSpice 9.1 and the same way is used to analyse single-phase ac circuit. We determined the value of generator current Iab‚ line current IbB‚ and the phase current IBC. Initially‚ PSpice is used to draw a schematic diagram of circuit A. Under the simulation‚ two major problems were occurred. First‚ a delta connected source is a loop of voltage sources which must be prevented when PSpice is used. To prevent

How to Operate a Manual Transmission A vast majority of our population find operating a manual transmission‚ or stick shift‚ to be extremely difficult. However‚ in actuality all it takes is some serious practice and devotion to make driving a stick shift like second nature. For successful driving‚ the same steps must be followed each time the car is driven. The stick shift panel is typically located between the two front seats of the vehicle. The stick shift can be moved left to right and

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Automatic Transmissions Work by Karim Nice If you have ever driven a car with an automatic transmission‚ then you know that there are two big differences between an automatic transmission and a manual transmission: There is no clutch pedal in an automatic transmission car. There is no gear shift in an automatic transmission car. Once you put the transmission into Drive‚ everything else is automatic! Both the automatic transmission (plus its torque converter) and a manual transmission (with its
