Planning for renewable integration. Renewable-energy providers are up against hard deadlines when it comes to initial delivery of new power to their utility customers. Failing to meet backfeed dates specified in power purchase agreements can result in big financial penalties. In this short video, Matt Vaughn, ABB's Business Development Manager – Renewables PSS NAM, talks about some of the things renewable-energy providers can do to ensure smooth integration in order to...
Preparing for FERC 797 (GIC). Power systems located in the far northern and southern latitudes are most susceptible to geomagnetically induced current (GIC) issues. Other factors – including resistance of the soil, length of the transmission lines, and proximity to water – also come into play. Watch this short interview with Ramsis Girgis, ABB's R&D Manager for Power Transformers, to learn more about the FERC 797 standard and how to mitigate potential GIC issues. ...
How to reduce the risk of transformer failure. 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,...
AC substation grounding for safety. This video provides a process to test and design a substation grounding system for safety. Some of the factors you need to consider in substation design include fault currents, surface coverings, power system configurations, and existing ground grid.

internal wiring of the transformers should be in complinace with NEC, sections related wire current capacity and the withstand to short circuit current. inaddition all wiring should be insulated and, when bolted connecions are made, the nuts should be visible.
