Capacitance Voltage Dividers: Capacitance voltage dividers are ideal for measurement of fast rising voltages and pulses. The capacitance ratio is independent of the frequency, if their leakage resistance is high…
Band Reject Filter Circuit: In this Band Reject Filter Circuit, frequencies are attenuated in the stop band and passed outside it, as shown in Fig. 15.20(b). As with band pass…
What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus possesses at least one pass…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive…
Gear Wheel Method for Frequency Measurement: When a Lissajous figure contains a large number of loops, accurate counting becomes difficult. Figure 7.35 shows a test method that uses a modulated…
Single Line to Ground Fault: Figure 11.4 shows a Single Line to Ground Fault at F in a power system through a fault impedance Zf. The phases are so labelled…
Equivalent Circuit of Long Transmission Line | Ï€ and T network: So far as the end conditions are concerned, the Equivalent Circuit of Long Transmission Line can be established in…
Introduction to Power Transmission Line: Introduction to Power Transmission Line deals primarily with the characteristics and performance of transmission lines. A problem of major importance in power systems is the…
