Extends measurement range to VHF and UHF ranges
The UHF 620 extends the measurable bandwidth of the partial discharge (PD) measurement device up to the VHF and UHF frequency ranges. PD can be measured in an additional measurement range of 100 MHz to 2,000 MHz with different frequency bandwidths, including narrow-band measurements up to 1.5 MHz, medium-band measurements at 70 MHz and broadband measurements at 1.9 GHz.

Key features

• Flexible adjustable measurement bandwidth
• Less interference due to narrowband measurements
• Simple configuration due to broadband measurements
• Decoupling of GIS measurement voltage possible
• Controlled directly via MPD software

Applications

• PD measurements on power transformers and GIS
• Commissioning tests
• On-line diagnostics
