How does a phase monitor work

WebDuring normal operation, the current flowing through each pole of an overload relay to the motor remains the same at a time. If anyone of the phase is interrupted, the current through the other two phases rises to 1.73 times the normal value. Hence the overload relay gets heated up and it trips. WebLCD displays work by using individual pixels to display visuals, moving or stationary. Each pixel will display a color mixed by the RGB color filter with each color’s filter associated with one of the pixel’s sub-pixels. The sub-pixels are where the degree of light is determined, thus affecting the degree of prominence of its respective color.
