Abstract
PURPOSE:To increase the economy and reliability, by integrating the original current and transmitting the measuring signal corresponding to the integration value so that the transient response current with steep or in rapid change can be measured from a remote location stably. CONSTITUTION:When a measuring start contact 3A is operated, a voltage proportional to a steep transient response current determined with a termination resistor 3B of a capacitor Cr is input to an integration circuit 3C and integrated with a resistor R and a capacitor C for the output. After a given time determined with a time constant, the integration value is almost at a constant value. A measuring signal transmission circuit 3D receives this integration value and converts a voltage into frequency after a given time continuously from the beginning or when the integration value is almost at a constant value, to form the measuring signal for the transmission to a transmission line 4. A given conversion is made to a received measuring signal at a display section 5, and a value corresponding to the output voltage of an integration circuit 3C is indicated on a voltmeter 5B.
