ECAD System 2002

An Improvement to Any Electrical Maintenance Program

(PDF Spec Sheet)

The ECAD System 2002 is a portable, ruggedized tester that can be used for troubleshooting and condition monitoring of installed circuits, cables and wiring harness.   The ECAD tester is a combination of traditional electrical measurements, a database for storing test results, and data analysis software.     This powerful combination allows a user to evaluate the condition of all circuit components  in a logical  and straightforward manner from one end of the circuit.

ECAD Test System

System Features & Benefits
  • Basic configuration performs the following measurements:
    • DC resistance (2-wire configuration, 0 Ω to 30 MΩ)
    • AC/DC voltage (0 to 330 VAC/VDC)
    • Impedance and Phase Angle (100 Hz to 40 kHz)
    • TDR (for circuits up to 1.5 km in length)
    • Insulation  resistance (up to 500 VDC)
  • Optional hardware can be easily added, including:
    • Standalone high voltage power supply and picoammeter for detector plateau characterization (I-V testing) for PWR applications
    • Integrated source measurement unit for detector plateau characterization in BWR applications.
    • Integrated switch matrix and multiplexers for automatic testing of large numbers of conductors or circuits
    • Connector break-out boxes and hardware
    • Customized adapter cables
  • ECAD test results can be used to identify and locate degraded or failed conditions within circuits, including:
    • Open or short-circuited conductors
    • Low resistance shunts to ground
    • Poorly quality connections
    • Resistive connections
    • Grounded conditions
    • Poorly matched coaxial or triaxial connections
    • Moisture intrusion
    • Brittle or cracked cable insulation

The ECAD System 2002 is being used extensively throughout the commercial nuclear power industry for a variety of applications, including:

  • Monitoring instrumentation during Integrated Leak Rate Testing (ILRT) to determine which circuit component is being impacted by the increased pressure
  • Performing I-V characterizations of nuclear instrumentation detectors to support a condition-based replacement strategy
  • Testing cables for license extension commitments to the NRC
  • Evaluating Control Rod Drive (CRD) components during refueling outages to monitor aging effects on the coils, cables, and connectors.
  • Provide an assessment of the Rod Position Indication (RPI) and CRD components to determine if these parts can re-used during a reactor head replacement.
  • Monitoring the condition of pressurizer heater elements for aging effects

All the above applications save time and money compared to traditional or alternative test methods.
