Dynamic Conditions of a SystemDrive: Dynamic or transient conditions occur in SystemDrive systems when the operating point changes from one steady state condition to another, following a change introduced in the system variables. These variables…
Bridge Rectifier Circuit Diagram with freewheeling diode: A 6 pulse Bridge Rectifier Circuit Diagram with freewheeling diode across the load terminals is shown in Fig. 3.58. As has already been explained, the diode participates in…
Ionization Processes: A gas in its normal state is almost a perfect insulator. However, when a high voltage is applied between the two electrodes immersed in a gaseous medium, the gas becomes a conductor and…
Per Unit System in Power System: Per Unit System in power system is usual to express voltage, current, voltamperes and impedance of an electrical circuit in per unit (or percentage) of base or reference values…
Induction Furnace - Definition, Types, Working Principle and Advantages: In induction heating effect of currents induced by electromagnetic action in the charge is employed. The heat developed depends on the power drawn by the charge.…
Power on Reset Circuit in 8051: On reset, the PC sets to 0000H which causes the 8085 to execute the first instruction from address 0000H. For proper reset operation reset signal must be held low…
Unbalanced Three Phase Circuit Analysis: Types of Unbalanced Loads - An unbalance exists in a circuit when the impedances in one or more phases differ from the impedances of the other phases. In such a…
Parallel Plane Waveguide: Parallel Plane Waveguide - As we know already in connection with transmission lines, that reflections and standing waves are produced if a line is terminated in a short circuit, and that there…
Brown Boveri Regulator: In this type of Brown Boveri Regulator, exciter field rheostat is varied continuously or in small steps instead of being first completely cut in and then completely cut out as in Tirril…
Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by the source itself. This is…
