Continuous Online Diagnostics

Doble has created a variety of online devices to manage the state of your bushings/CTs, transformers, circuit breakers, and other apparatus.
 

DOMINO

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.

Intelligent Diagnostic Devices

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.

LCM 500

Use the LCM 500 Leakage Current Monitor to check the metal oxide surge arresters and investigate details in leakage current changes versus time to detect deteriorating trends, with no interruption of service. This portable, cost-effective system creates a unique identification for each surge arrester, allowing easy data management with the Windows-based LCM 500 software.
