Книга: Abhishek R.,Ashrith N. and Arjun N. «Phase Angle Measurement using a PLL»
Производитель: "LAP Lambert Academic Publishing" Phase angle measurement between two AC waveform having same frequency is needed in various applications like 3-phase transformer connection,CT and PT installation,Power factor determination. Conventional phase angle meters are bulky and costly. A new method for measuring phase angle using a digital PLL is proposed with operating frequency range of 20Hz to 1kHz. This design also has lag/lead identification feature and is cost effective. The phase angle meter involves phase detection using PLL, frequency to voltage conversion, calibration and display. A regulated power supply and a phase shifter circuit are also designed to test the phase angle meter. A 3 1/2 digit LED display panel meter is used to display the final measured phase difference between two AC waveforms fed as input.
