Installation of a typical 10 Phasor PMU is a simple process. A phasor will be either a 3 phase voltage or a 3 phase current. Each phasor will, therefore, require 3 separate electrical connections (one for each phase). Typically an electrical engineer designs the installation and interconnection of a PMU at a substation or at a generation plant. Substation personnel will bolt an equipment rack to the floor of the substation following established seismic mounting requirements.Its job is to turn synchronised ADC samples into phasor frames with timestamps that share the same time base as protection relays, power quality meters and SCADA or WAMS systems. The PMU signal chain can be viewed as four time-critical stages: acquisition → timestamp → compute →. . Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity. .
