LDS-6/UHF

Portable PD Analyzing System LDS-6/UHF for PD measurements and monitoring on GIS, Cable Systems and transformers

Applications

  • The LDS-6/UHF is a state-of- the-art, portable digital measuring system for the UHF processing of partial discharges acquired from installed GIS sensors, or UHF sensors. It combines the features of a PD detector and spectrum analyzer.
  • PD quality tests on GIS using installed GIS sensors
  • PD testing on HV Apparatus, using UHF technology
  • Designed for on-site PD diagnosis tests as well as for manufacturing and research
  • Single channel or Dual channel
  • Available in 19" housing with external PC connected via Ethernet, or portable case with built in mini PC
