Electrical appliance diagnostic system IDD

Doble's Intelligent Diagnostic Devices (IDDs) are a cost-effective online diagnostic system used to monitor electrical apparatus in the field. Each IDD is intended to be apparatus-specific and can be mounted in existing enclosures or in optional enclosures available from Doble. The IDD is easy to install and, once configured, operates continuously. Application: Continuous on-line monitoring of bushing Power Factor/Tan Delta and capacitance via test tap. May also be used for hydrogen and/or moisture in oil via Doble or third party sensors. Doble IDD versions: • IDD for Moisture in Transformers • IDD for Dissolved Gas in Oil Analysis (DGA) • IDD for Bushings and CT's Features and Benefits: • Continuous Condition Assessment. The status of the equipment is constantly being evaluated by the field-proven Expert System, minimizing the need to perform routine testing. • Early Identification of Problems. Refined signal processing and field-proven analysis identify abnormalities, anticipate failures, and eliminate false alerts. • Prioritized Alerts. Based on the significance of the incipient problem, the analysis issues 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. • Simple Installation. The IDDs is a self-contained device that requires only connecting sensors, input power, and optional remote communication to complete the installation with minimum outage time and resources.
