PROBLEM TO BE SOLVED: To provide a measurement device capable of accurately measuring the quantity of electricity that is outputted from distributed power sources even at a startup time in which output of the distributed power sources is weak.SOLUTION: The present invention relates to the measurement device for measuring the quantity of electricity that is supplied from the distributed power sources. The measurement device comprises: a power input part 20 which inputs power from the distributed power sources; a converter 21 which converts the power inputted from the distributed power sources into a predetermined voltage; a calculation part 22 which processes a measurement signal that is inputted from a measurement sensor 16; a connection part 26 which supplies the power outputted from the converter 21 to external equipment 17 as drive power; and a current limiter 28 which limits a current to be supplied to the connection part 26 equal to or less than a fixed value. The current limiter 28 is functioned only in the state where power outputted from the converter 21 is equal to or less than a fixed value.SELECTED DRAWING: Figure 4 |
