Time Base Generator - Working Principle and Types: Time base is an axis, normally X-axis, that is used to represent time so that variations of quantities such as voltages, currents…
Generator Inter Turn Fault Protection: Merz-Price circulating current protection system does not provide protection against turn-to-turn faults (short circuits between the turns) on the same phase winding of the stator…
Sawtooth Voltage Generator Circuit Diagram and Waveforms: Figure 30.129 represents a basic sawtooth voltage generator. Switch S periodically changes its position from point 1 to point 2 (although a mechanical…
8253 Programmable Interval Timer: 8253 Programmable Interval Timer - In the process control system or automation industry, a number of operations are generally performed sequenÂtially. Between two operations, a fixed…
Clock Generator 8284A: During fetch and execute instructions, the 8086 and 8088 processors require clock pulse which has about 10 ns rise and fall times. The logic 0 level of…
Tripping of Impulse Generator: In large impulse generator, the spark gaps are generally sphere gaps or gaps formed by hemispherical electrodes. The gaps are arranged such that sparking of one…
Microprocessor Based DCS: Microprocessor Based DCS - Modern plants nowadays are very complex, large scale systems with a very high degree of automation. The designs and the operation of these…
Pulse Time Modulation(PTM): In Pulse Time Modulation the signal is sampled in the same way as in PAM, but the pulses indicating instantaneous sample amplitudes have a constant amplitude themselves.…
