XD50 Combined Partial Discharge Analyzer

The XD50 combined partial discharge (PD) analyzer is our latest PD analyzer model designed to fit any use case where quick measurement and analyzing is needed. The analyzer supports four means of testing: AE, UHF, HF, and TEV, with arbitrarily configurable channels. A wide range of accessories makes it fit most types of electrical installation: transformer, GIS, SF6 circuit breaker, switchgear, and power cable. The analyzer is lightweight and compact, but packs all the advanced features.
