CONTINUOUS ONLINE DIAGNOSTICS

Application: Transformers / Circuit Breakers

Intelligent Diagnostic Devices (IDDs), a family of continuous online diagnostic devices for power system apparatus, are designed to detect incipient problems with bushings/CTs, transformers, and circuit breakers. Now you can safely manage progressive problems and efficiently schedule corrective action. There are three types of IDD instruments: Moisture, Bushings, and Dissolved Gas Analysis

IPM is designed to perform­ continuous online m­onitoring of external pollution effects on high-voltage insulators and other insulator housings, such as surge arresters and bushings. By m­easuring the surface leakage current of the insulators, IPM can classify the severity of the pollution. You can use this information to m­ake decisions on insulator maintenance.

The LCM II Leakage Current Monitor measures the resistive component of continuous leakage current in gapless metal oxide surge arresters (MOSAs). Increased resistive leakage current indicates a higher risk of MOSA breakdown.

Accurate moisture and temperature data is necessary to determine the condition of electrical apparatus or its insulating liquid. However, the data by itself may not always be sufficient to identify potential problems, especially in transformer systems. Doble developed one of the first analytical techniques for measuring dissolved water in oil and the first online moisture monitor: DOMINO.
