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…
Per Unit System: While carrying out the analysis of electrical machines (or electrical machine systems), it is usual to express voltage, current, VA and impedance in Per Unit System (or percentage) of the base or…
Pentium Pro, Pentium II and Pentium III Processors: Pentium Pro The Pentium Pro is a sixth-generation x86 microprocessor and it was introduced by Intel in 1995. This processor was developed based on the P6 micro-architecture.…
Pentium MMX Processor: Pentium MMX Processor - MMX stands for Multimedia Extension, Multiple Math Extension, or Matrix Math Extension. The MMX is a Single Instruction Multiple Data (SIMD) instruction and it was designed by Intel…
Pentium Bus Interfacing: Pentium Bus Interfacing - The Pentium processor has a 64-bit data bus which increases data transfer rates over previous generation processors, and the processor bus is used for connection to a fast…
Peak to Peak Detector - Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal. The same circuit with a…
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…
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 of the voltage and co…
Paschen Breakdown | Paschen's Law | Paschen curve It has been shown earlier (refer Sec. 2.6) that the Paschen Breakdown criterion in gases is given as where the coefficients α and γ are functions of E/p, i.e…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation factor (tan δ) was voltage…
