An electrical circuit for connecting an electrical measurement device (16), which is used to measure partial discharges in a power grid having an operating voltage in the range of 1-69 kV, and which has an A/D converter (17) for converting a measured voltage pulse into a digital signal and has a microprocessor unit (18) for evaluating the digital signal, with a measurement output of a capacitive voltage testing system (3) of switchgear for the power grid having the operating voltage in the range of 1-69 kV. The electrical circuit (8) has a frequency response matching resistor (9) which is connected between an input line (10) for connection to the live pole of the measurement output and to ground, and has a high-pass filter (11) connected down-circuit of the frequency response matching resistor (9).
An electrical circuit for connecting an electrical measurement device, which is configured for measurement of partial discharges in a power grid having an operating voltage in a range of 1 kV to 69 kV, and which includes an A/D converter for converting a measured voltage pulse into a digital signal, and a microprocessor for evaluating the digital signal, with a measurement output of a capacitive voltage testing system of switchgear for the power grid which has an operating voltage in the range of 1 kV to 69 kV, the electrical circuit comprising:
