Portable partial discharge monitor PDA-IV™

The PDA-IV is a portable instrument specifically designed to monitor PD in hydro-generators equipped with PDA Couplers. The PDA-IV instrument determines the magnitudes, rates and polarities of voltage pulses created by partial discharges. Additional parameters such as NQNs and peak pulse magnitudes are also calculated. The instrument comes equipped with user selectable RS232, USB, or Ethernet (TCP/IP) communication ports. An external computer is used to control data acquisition, display, and store PD test results quickly and conveniently.
