Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

When should you replace High Voltage equipment?

Historical Growth and Ageing AssetsRisk AssessmentReasons to ReplaceDuring the post-war economic industrial boom period of the 1960s and 70s large volumes of High Voltage transformers and switchgear were installed throughout Britain as manufacturing soared and the demand for power followed. It is now understood that high voltage asset stock from this period has exceeded its design life cycle, and replacement should be considered in order to maintain a safe and reliable power supply. Although switchgear and transformers can be replaced based upon an assessment of various factors that cause degradation, such as operating conditions and environment, plus the type of equipment and maintenance history, ultimately age plays a key role in the decision-making process for replacement. Within the high voltage engineering community there is a well-regarded industry rule of thumb that switchgear and transformers have a service design life of around 40 years. However, independent service life-cycle theories have also focused on the one element that prevents the...Get price
