Comments: We have been using one 60KW and ten 1.5KW 3-phase Power Savers for a month since we bought them for our club on July 26, 2004. We paid 13,860 yuan for power last month and the bill for this month is 10,094 yuan. We can see the devices are obviously effective in power saving. All the electrical appliances have been running properly since the installation of Power Savers. The total saving rate is around 27%.

Data analysis:
In Table 1, the total test time is 1759.7 hours and the power consumption is 259.6kwh (309.5-49.9). Table 2 indicates a total test time of 1635.8 hours and power consumption of 290.1kwh (340.9-50.8).
The results show that the computer group with Power Saver, despite its longer time (123.9 hours longer), has consumed 30.5kwh less than the other group. About 21kwh power is consumed in 123.9 hours, which means 10 computers have saved 51.5kwh in 10 days. So it¡¯s concluded that approximately 154.5kwh (51.5 ¡Á3) power can be saved by 10 computers with Power Saver in a month.
