Dissipation Factor in Schering Bridge: Extension of range of the Dissipation Factor in Schering Bridge can be achieved by connecting in parallel an additional large capacitance across C3. But to…
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…
Peak Reading AC Voltmeter Circuit: Peak Reading AC Voltmeter Circuit : When a capacitor is connected to a sinusoidal voltage source, the charging current where V is the rms value…
Capacitance Voltage Transformer: The errors due to harmonic voltages can be eliminated by the use of capacitive voltage dividers with an electrostatic voltmeter or a high impedance meter such as…
AC Field Strength Meter: AC Field Strength Meter is usually measured by introducing a small fixed capacitance probe into the field area and measuring the induced charge on it. Since…
Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter as shown in Fig. 7.1. Only the…
Generation of High Frequency AC High Voltage: High Frequency AC High Voltage are required for rectifier d.c power supplies. Also, for testing electrical apparatus for switching surges, High Frequency AC…
Solid Dielectrics Used in Practice: The majority of the insulating systems used in practice are solids. They can be broadly classified into three groups: organic materials, inorganic materials and synthetic…
