Asset-intensive industries face increasing pressure to improve how well they utilize and maintain their equipment. Asset health management is emerging as a critical business process due to the potentially very significant bottom-line impact of asset decisions on profitability, compliance and customer satisfaction....More
Current and voltage measurements are two key functions in the control and protection of electric power grids. Traditionally, they have been performed using so-called instrument transformers – somewhat bulky and heavy devices that can weigh up to several tons....More
Using advanced converter technology developed by abb, the world's first hvdc transmission with voltage source converters began transmitting power in 1997. This technology was introduced as hvdc light. The new transmission link ran along a 10 km route between the swedish towns of hellsjön and grängesberg. It was rated at 3 mw / ± 10 kv dc....More
A new study finds that distributed generation, energy efficiency, storage, microgrids, and other innovations add resilience and dynamism to the grid, but do not obviate the need for major expansion of the high-voltage, bulk power system....More

The Federal Energy Regulatory Commission last week acted to promote broader regional transmission planning in the U.S. Western Interconnection by clarifying that an Order No. 1000 regional transmission planning process may conduct transmission planning on behalf of non-public utility transmission providers,...More
On-load tap changers are often the culprit when power transformers fail. Trouble with mechanical components and coking of contacts are frequently at fault. In this video, you can explore the design of some of the most commonly used tap changers and discover the strengths and weaknesses of each. You will also learn about options to repair or retrofit troublesome tap changes and maximize transformer life. Download the white paper, “Repair or replace? The $64,000 (or much more) question facing utilities,” for in-depth information on how to extend the life of your transformers.
