Abstract
The principle of power measurement by thermal means has the advantage of a very large bandwidth and gives the possibility to realize time or frequency encoding in a simple way. The new method described is based on a known operation using special thermal converters with several heaters. The multiple heating, however, is done by a multiplexing operation on single-heater converters. It is shown that, by means of this principle, a power meter can be set up enabling precision measurement in a wide range of frequency. The measurement of real power in polyphase systems is another application of the same principle.Keywords
