ABB instrument transformers to support Progress Energy smart grid project

Raleigh, N.C., August 25, 2009 – Progress Energy has selected ABB’s HCEP medium voltage instrument transformers for their smart grid implementation plans.

The increased life-expectancy and reliability of these HCEP instrument transformers will help reduce Progress Energy’s maintenance costs by minimizing the risks of costly substation power outages, and ultimately improving their smart grid reliability.

Over the next 18 months, the ABB operation in Pinetops, N.C., will provide installation of more than 400 HCEP instrument transformers at over 140 substations in North and South Carolina.

Since its introduction in 2006, ABB’s HCEP (hydrophobic cycloaliphatic epoxy) outdoor medium voltage instrument transformer has become recognized as the most advanced solution for metering and relaying applications, ranging from 5 kV to 52 kV. HCEP is an advanced insulating material designed to improve weatherability and reliability in all outdoor environments.

Each substation will utilize one set of three potential transformers, allowing the Raleigh, NC-based utility to accurately determine substations regulator tap positions. This will keep voltage levels in substations within acceptable and controllable bandwidth, thus avoiding undesirable conditions to occur to their connected customers and providing the accuracy required by Progress Energy’s distribution management system.
