Original Abstract

This article deals with the design and implementation of a pulse generator serving as a cali-bration generator for setting up measuring systems for monitoring the activity of partial dis-charges (PD) in the high-voltage power transformers or gas insulated switchgears (GIS). After installing the measuring device, it is advisable to test the entire measuring chain and, if neces-sary, set parameters that would affect the correct detection of PD signals. Calibration pulse generators are used for setting and validating measuring chain. These are usually used in sys-tems that sense the electromagnetic activity of PD. Correct and timely detection of PD can avert a transformer accident and thus contribute to higher safety in power plants. The pro-posed generator should serve as the output part of a programmable generator, which did not reach sufficient parameters of output pulses. The goal was to achieve a rising time around 100 ps and an amplitude of more than 6 V using modern and very fast operational amplifiers and step recovery diodes as a sharpener of the input pulse. The measurements show wave-form of the output voltage pulse.
