EMI Surveyor

Doble’s EMI Surveyor is an in-service, EMI testing solution that can identify more than 70 different electrical and mechanical defects in generators, motors, bus duct and other high-voltage (HV) electrical plant equipment.

The EMI Surveyor measures the release of electromagnetic (EMI) energy resulting from HV electrical insulation-related partial discharge defects, corona, random noise, as well as LV/HV mechanical conductor-related arcing defects and sparking.

The EMI Surveyor includes all the accessories needed for a comprehensive EMI testing assessment: PDS200 spectrum analyzer, EMI sniffer, split-core high-frequency current transformer, wireless synchronization adapter and all required antennae and cables.

    • Portable, easy to use, handheld devices
    • Packaged kit includes all accessories needed for a comprehensive EMI assessment
    • Provides dual EMI and RFI partial discharge spectrum capabilities
    • Easily connects to multiple sensors including high-frequency current transformers, UHF drain valve, TEV probes, and directional antennae for various applications
    • Acoustically listen to radio noise generated from defects
    • Signal can be power cycle synchronized to facilitate phase resolved PD analysis 

    • Efficiently plan outages by improving prioritization of needed maintenance & repairs
    • Non-invasive, in-service electrical “system assessment” surveying solution
    • No permanent high-voltage connections mitigating arc flash hazards
    • Proven technology providing asset maintenance recommendations after the first test

  • PDViewer Software
     

    • Use the PDViewer software on your computer to view and edit the survey files created on your handheld PD tools
    • PD spectra and time resolved plots can be displayed, overlaid and compared in a simple user interface
    • Examine RFI and acoustic data; overlay or compare multiple traces side-by-side
    • Registered users can download the latest PDViewer software and documentation

  • Leverage Doble’s expert EMI Diagnostics field services team to perform testing at your plant for a comprehensive electrical plant assessment. Doble can also provide comprehensive classroom and field data acquisition training, enabling your team to capture EMI and partial discharge data and forward results to Doble’s experts for detailed data analysis, report generation and follow up consultation.

     

    A typical training session would include:

    • Overview of EMI, PD and RFI detection applications
    • EMI fundamentals
    • International standards
    • Working with the EMI Surveyor
    • Taking reliable measurements
    • Analyzing data for proper data acquisition
    • Managing data and firmware
      Overview of PDViewer software
