Inventor: TOITA SHIGETO
IPC: G01R11/02
Filed: 2002-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that, since the conventional watthour meter with a transmission unit so far discriminates the maximum pulse width (pulse-on time) which can assure the ratio of the pulse-on time to the pulse-off time and outputs a pulse based on the result, the meter needs the setting process of the pulse width and cannot assure the pulse-on time necessary to recognize the pulse by a receiver depending on the set value of the pulse width, so that it is not possible for the receiver to perform normal metering.  <P>SOLUTION: The watthour meter with the oscillating unit comprises a measuring means for outputting the pulse in a frequency proportional to a power to be input from a power distribution circuit, a control means for outputting the pulse obtained by frequency-dividing the pulse, the oscillating unit for oscillating the frequency-divided pulse to the receiver, and a storage means for storing the pulse-off time which can be received by the receiver.
