Busbar Arrangements in Substations: Busbar are the important components in a sub-station. There are several Busbar Arrangements in Substations that can be used in a sub-station. The choice of a particular arrangement depends upon various…
Voltage Source and Current Source: According to their terminal Voltage Current Characteristics, electrical Sources of Energy are categorized into ideal voltage source and current source. Further they can be divided into Independent and Dependent sources.…
Maximum Mode Configuration of 8086: A processor is in the Maximum Mode Configuration of 8086 when its MN/MX pin is grounded. The maximum mode defines pins 24 to 31 as follows: Pin Definitions (24 to…
Loeffler Boiler Construction and Working Principle: The major disadvantage in La Mont boiler is the deposition of salt and sediment on the inner surface of the water tubes. It reduces the heat transfer and ultimately…
Sumpner Test of Transformer: While OC and SC tests on a transformer yield its equivalent circuit parameters, these cannot be used for the 'heat run' test wherein the purpose is to determine the steady temperature…
Duty Cycle of Traction Drives: The Duty Cycle of Traction Drives in trains is explained with the help of speed-, torque- and power-time diagrams (Fig. 10.6) which are drawn for travel between two consecutive stations…
Classification of High Voltage Laboratories: Classification of High Voltage Laboratories depending on the purpose for which they are intended and the resources (finances) available, can be classified into four types. Small laboratories Medium size laboratories…
Difference between Combinational Circuit and Sequential Circuit: The difference between combinational circuit and sequential circuit is given in table below Sl no Combinational Circuit Sequential Circuit 1 In combinational circuits, the output variables are at…
Energy Density Formula in Magnetic Circuit: The Energy Density Formula of transformers, ac machines and several other electromagnetic devices are excited from ac rather than dc sources. With ac operation, inductance is effective even in…
Capacitance of Three Phase Line with Unsymmetrical Spacing: Figure 3.7 shows the three identical conductors of radius r of a Capacitance of Three Phase Line with Unsymmetrical Spacing. It is assumed that the line is…
