Surface tracking on xlpe cable insulation ⚡️ Few key features: - 0-90 degree negative pattern is approximatly 3 times smaller than positve pulses at 160 - 250 degrees. - Discharge finishes abruptly at 250 degrees. - PD pulses are incepting slightly before the 0 crossing. - Shape of PRPD also help assist classification. Please feel free to share your findings and knowlege on this topic. Easy discharge to create but also can cause a great amount of damage to the insulation quickly. #partialdischarge #perth #highvoltage #neverstoplearning #Transformers #cables #rotatingmachines #HVtesting #online #offline #50HZ #conditionmonitoring #wefindwefix #ruggedmonitor #cpm601
Using RUGGED MONITORING CPM601?
Petr Mráz give your expert comments. Please :)
This is great
Can you please elaborate about PD pattern and analyse it?
Thanks for sharing, the charge magnitud seems to high for a cable system, can you talk about the location of this activity, please. Is it in jointing o termination accessory?
Fascinating insights into surface tracking on XLPE insulation It's amazing how quickly these discharges can cause significant damage to the insulation. Thanks for sharing this! Looking forward to seeing more contributions and findings on this topic

3moGreetings, do you have a manual for the analysis of PD in XLPE cables, will it be possible can you explain a little about the analysis of this type of PD?
