(S) (2§ IDD® INTELLIGENT DIAGNOSTIC DEVICES Introduction A family of continuous online diagnostic devices for power system apparatus intended to detect incipient problems with bushings/CTs, transformers, and circuit breakers. Now, progressive problems can be managed safely, and replacement can be deferred until corrective action can be scheduled efficiently.
Features •
Rugged and Reliable - Designed to operate reliably in electrically noisy substations and in extreme weather conditions. •
Self-Diagnostics - The firmware will
monitor critical signals continuously for proper operation of the
IDD. Indication of the malfunction is given locally as well as remotely.
• Web Browser PC interface - The
IDD can be accessed via a standard web browser available on all PCs. No special software installation is required on the PC. •
Continuous Condition Assessment - The status of the apparatus is constantly being evaluated by the field-proven diagnostic expert system, minimizing the need to per-form routine testing.

Early Identification of Problems - Refined signal processing and field-proven analysis will identify abnor-malities, anticipate failures, and eliminate false alerts. •
Prioritized Alerts - Based on the significance of the incipient problem, the analysis will issue an alert indicating the criticality of the problem, providing a tool to manage risk. •
Specifies Corrective Action - An alert identifies the problem and prompts corrective action required to resolve the problem.
-.0 00 000 escription The
IDD, Intelligent Diagnostic Device, is a cost-effective online diagnostic system used to
monitor electrical apparatus in the field. Each
IDD is intended to be apparatus spe-cific and can be mounted in existing enclo-sures or in optional enclosures available from Doble. The
IDD is easy to install and, once configured, operates continuously. The
IDD contains a state-of-the-art microprocessor-based signal processing module, a control panel for user interface, alert indications, an RS-232 serial port for local PC access, as well as options for remote communication. The
IDD software system acquires data through the data acquisition board and ana-lyzes this information using the field-proven expert diagnostic system. The software provides an assessment of the apparatus on a continuous basis. This eliminates the need for an external server or database. An
IDD can be configured for analysis of various subsystems by simply installing the appropri-ate data acquisition board.
• Simple and Easy Installation - A self-con-tained device which simply requires connecting sensors, input power, and optional remote communication to complete installation. Minimum outage time and resources are needed for installation.
