Comparison of Monitor Types in Personal Computer Set on Electrical Energy Saving and Side Effect on Power Quality

Abstract:

This paper presets comparisons of type of monitor in personal computer set on electrical energy saving and side effect on power quality. The 3 types of monitor in personal computer consists of cathode ray tube : CRT type inch, liquid crystal display : LCD type, and light emitting diode : LED type and side of each monitor is 19 inch. The experimental results as shown the power consumption and side effect on power quality such as power factor and %THDi each monitor types. The experiment results shown the best effectiveness is LED monitor type, it can be saving of energy up to 75.69 % of CRT monitor type and 45.30 % of PC. Set with CRT monitor type. However, the LED monitor type are generated of %THDi very high level and low level of power factor.
