Abstract
The invention relates to measuring apparatus for measuring the real load factor on an electricity source delivering an AC current to a consumer appliance, said apparatus comprising: a current sensor supplying a signal that is continuously proportional to the current delivered by the source; a rectifier circuit receiving said signal and supplying a rectified signal; a peak detector circuit receiving the rectified signal and extracting therefrom the peak value, which peak value can be read on an indicator; and calibration means enabling the measuring apparatus to be set so that the peak value indicator displays 100% when the measured peak value of the AC current reaches the specified maximum level.
Claims7
A measuring apparatus for measuring the real load factor on an electricity source delivering an AC current to a consumer appliance;
- wherein the apparatus comprises:
- a current sensor supplying a signal that is continuously proportional to the current delivered by the source;
- a rectifier circuit receiving said signal and supplying a rectified signal;
- a peak detector circuit receiving the rectified signal and extracting therefrom the peak value;
- an indication means for displaying a percentage value comprised between 0% and 100%;
- and
- means for adjusting the gain of the measuring apparatus so that the indication means displays 100% when the measured peak value reaches a specified maximum level which is the highest peak intensity which can be supplied by the source.
