An instrument () and a method for measuring pulses of partial electrical discharges in an electrical system comprise data processing means () operatively associated both with an input stage (), able to receive an analogue signal () representing said pulses and to provide a digital representation of the entire wave form of the pulses, to receive said digital representation, extract the value of predetermined parameters relating to the wave form of the pulses and transfer to and output stage () a processed digital signal comprising said values, the processing means () being able to operate substantially in real time, i.e. with no need for a memory for the intermediate storage of the data. Known solutions within the field of the measurement of partial discharge pulses for diagnostic purposes provide for the use of peak detector instruments, which are not able to measure all information useful for a diagnosis of the electrical system, and oscilloscopes interacting with a computer, disadvantageous in terms of costs and of calculation efficiency.
