What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
Ultrasonic Transducer: Ultrasonic Transducer (sound vibrations above 20 kHz) are useful when we are concerned with rapid temperature fluctuations, temperature extremes, limited access, nuclear or other severe environmental requirements and…
Working Principle of Digital Multimeter: Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters…
Trends in Voltage Stability of Power Systems: Trends in Voltage Stability of Power Systems - The present day transmission networks are getting more and more stressed due to economic and…
Long Term Load Forecasting in Power System: Long Term Load Forecasting - If the load forecasts are required for planning purposes, it is necessary to select the lead time to…
Types of Facts Controllers in Power System: The development of FACTS controllers has followed two different approaches. The first approach employs reactive impedances or a tap changing transformer with thyristor…
Introduction to Power System Analysis: In earlier article we have been primarily concerned with the economical operation of a power system. An equally important factor in the operation of a…
Factors Affecting Transient Stability: Factors Affecting Transient Stability - The two-machine system can be equivalently reduced to a single machine connected to infinite bus bar. The qualitative conclusions regarding system…
