How much power does a plasma TV really consume?
The amount of electrical power consumed by a plasma TV varies constantly depending on the displayed image, unlike that of a CRT or LCD TV. “Rated Power” (IEC60107 3.6.2)* is apropos for measuring the power consumption of equipment that uses a constant amount of electricity. This makes “Rated Power” a rather inappropriate method for determining the power consumption of plasma display devices. What is a more efficient way to measure the precise power consumption of plasma TVs? Panasonic has concluded that the most suitable method is to measure power consumption while displaying an actual broadcast programme. Therefore, Panasonic has adopted a specification called “Assumptive Actual Use Power Consumption”. The consumption value is obtained by measuring the electrical power that is consumed during selected actual broadcast programmes for a period of ten minutes, then multiplying the result by six. *Standard of the International Electrotechnical Commission.
