IDD (Intellig. Diagn. Device)

IDD (Intellig. Diagn. Device)

Product catalog summary
Applications
The Intelligent Diagnostic Device (IDD) is used for monitoring suspect bushings and/or current transformers (CTs) and critical transformers.
Benefits
The IDD provides continuous and cost-effective assessment, eliminates forced outages by diagnosing problem severity using expert system software, and reduces false alarms through advanced signal processing and field-proven algorithms. It processes large amounts of data and notifies users only when necessary with detailed alert messages.
Specifications
  • Inputs: Supports up to 12 bushings (4 sets of 3), up to 3 moisture-in-oil sensors, up to 3 dissolved gas sensors, and 2 SCADA inputs for acknowledging and resetting alerts.
  • Outputs: Provides 4 SCADA outputs for action alerts, warning alerts, information alerts, and self-monitoring.
  • Communications: Includes Ethernet TCP/IP, RS485 (DNP3 and ASCII), Modem, RS232 (DNP3 and ASCII), and supervisory I/O.
  • Operating Environment: Functions in temperatures from -40° to +65°C and 5 to 95% relative humidity.
  • Power Supply: Operates on 100 to 280 VDC or 90 to 264 VAC.
Solutions
The IDD can be combined with other transformer monitoring systems, such as Partial Discharge Monitoring.
Accessories
Available accessories include a large range of bushing tap adapters, enclosures, shorting blocks, and fibre-optic communications.
