چکیده:

The accurate evaluation of current and voltage magnitudes from instantaneous measurements is now possible with a new technique. It is based on a freshly developed transform which allows evaluations, at intervals of one millisecond or less, between successive measurements. Not only
can accurate magnitudes of current and voltage be evaluated but derived values, such as active and reactive power, can also be computed between measurements. The new technique provides accurate evaluations even at speeds that are 100 times faster than can be achieved with existing measurement methods.
