- Abstract:
- Surge wave diagnostics is based on the principle of discharging two identical capacitors (highfrequency surge) into two loads (windings), and subsequent displaying resonant damped processes on loads by means of the two-channel oscilloscope. To increase the ability to identify failures, this signal must be, however, digitised and analysed by means of a mathematical tool. Generally, it has been stated that through this method, one of ten turn-to-turn short circuits can be identified without digitising the signal; after signal digitising, the identification of failures being improved approximately tenfold.
