dobleARMS® to support National Grid SA’s grid reliability programme

USA, Massachusetts: National Grid Saudi Arabia has contracted Doble Engineering Company, a subsidiary of ESCO Technologies Inc., for advanced services to support a new phase of its power grid reliability initiative, which will expand transformer health programs into additional regions.

Since June 2014, the two organizations worked together to perform asset health reviews on nearly 1,700 transmission transformers located mostly in National Grid Saudi Arabia’s Western, Southern, and Eastern Operating Area, using both time-based and predictive maintenance philosophies. The new project will extend this approach on additional transformers located mostly in the Central Operating Areas and will continue to review data for the other regions. This will effectively bring all of the organization’s transformers under diagnostic surveillance.

As part of this effort, Doble will be implementing dobleARMS®, an Asset Risk Management System with automated diagnostics based on failure modes and effects analysis. This will deliver 24/7 access to information and visualization of data and diagnostic information.

The new agreement also includes the continued review of testing and maintenance practices, a comprehensive study of National Grid Saudi Arabia’s in-house electrical insulating oil laboratories, and the ability to leverage Doble’s experience for the ongoing condition assessment of transformers.

Mr. Mohammed Muaili, Head of the Technical Support Department (TSD) of National Grid Saudi Arabia noted that “this is an important program for Asset Management of the transformer fleet and part of National Grid Saudi Arabia’s practice of continuous improvement.”
