Summary: This report describes the work carried out to develop a delta 420 kV compact line with 5 m phase spacing, utilising line surge arresters and elimination shield wires. Long term audible noise meaurements were taken on a full-scale outdoors test line. Special grading rings were developed and tested. The design is based on tension towers only, to overcome the clearance problems of short insulator strings on compact towers. Paper presented at Cigré general session, Paris, 1998.

Summary: 3-page article from ABB Technology magazine "ABB Review 2006/1" (Gerald Lee):
The world-class ABB high-voltage breaker facility in Mt. Pleasant, PA opened in April 2003 and serves as the US headquarters for high-voltage power technology products. This new facility has been designed to produce SF6 dead-tank circuit breakers for use in applications from 38 kV to 800 kV. However, on a more impressive note, lead-times, floor space, capacity and productivity have all been greatly optimized. How this was done will be explained in the body of this article.

Summary: 5 page article from the ABB Technolgy magazine "ABB Review - Special Report "Dancing with the dragon" 2008 II (Authors: Walter Holaus, Fredi Stucki):
China is in urgent need of electrical power. Huge power plants are built all over the country and the enormous flow of electrical power to the large megacities has to
cross several thousand kilometers from the source to the end user.
At those dimensions, losses of the power lines can be significant. The State Grid Corporation of China (SGCC) is thus aiming for 1,100 kV as the voltage level for AC transmission to keep losses as low as possible, a step into a new area of electrical grids.
ABB, together with its partners and suppliers, has developed the heart of such a system – a gas-insulated switchgear design – that could pass all the tests with this groundbreaking technology.

Summary: Results from pollution withstand tests on polymer-housed metal-oxide surge arresters are given. The results are used to calculate the risk for flashover of arrester insulators at different pollution levels and for different selection of creepage distance. The calculations are calibrated against long term field test results at two heavy polluted test sites in UK and South Africa. The outcome of the calculations indicates that it is possible to significantly decrease the required creepage for arresters in coastal areas with the use of polymer-housings with silicone rubber as external insulation. Paper presented at Cigre joint colloquium, Tokyo September 2005.

Summary: Since some years, arresters with polymer-housings have been available on the market for distribution and medium voltage systems. In recent years, this type of arresters have been introduced also on higher voltage systems up to and including 550 kV. However, the international standardisation work is far behind this rapid development and many of existing designs with polymer-housings for high voltage systems have only been tested according to existing IEC standard, IEC 99-4 of 1991, which in general only covers arresters with porcelain housings. Paper presented at GCC Cigré 9th symposium, Abu Dhabi, October 28-29, 1998.

Summary: Tranmission line arresters may be subjected to high energy stresses caused by lightning. Calculations of energy stresses were carried out for a typical line arrester installation. Three line configurations with different degree of shielding efficiency were used for the study. The calculated results were compared with energy stresses in standardized tests on surge arresters.

Summary: 5-page article from ABB Technology magazin "ABB Review 2002/3" (Willie Freeman, Helmut Heiermeier):
The next time you reset a 10-A miniature circuit-breaker in your home, spare a thought for the breakers, perhaps just a few miles away, that have to handle currents as high as 80,000 A. Up at the 245-kV level, these highly engineered devices, each the size of a small car, are traditionally of the oil or two-pressure type. In short, they are relatively complex and cumbersome.
A third, altogether simpler, cheaper and easier-to-use type of breaker, the SF6 dead tank puffer breaker, has never been used before for these elevated and highly demanding ratings.
Now, ABB is doing just that, with a new 80-kA design that combines a single-break puffer interrupter with the proven type PM dead tank breaker.
