  • 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 with

  • The Absence of Voltage Tester: What it is and what it isn't

    SummaryA New Approach to An Old ProblemThe Procedure For Verifying The Absence of Voltage Gets An UpgradeBy Rachel Bugaris, Business Development Manager, Panduit Corp We work in remarkable times. To stand for safety means to stand for innovation in a more connected and efficient world. In today’s market, where skilled workers are in high demand, and tenured workers are harder to find, it’s incumbent on the purchasers of electrical equipment to demand, and manufacturers of electrical equipment to create, new products that make it safer to work with electrical systems. Workers depend on the right tools to get the job done. And workers depend on their employers to ensure they’re equipped with the right tools, the right conditions, and the right processes to get the job done safely. It’s those conditions and processes that can - and are - being improved. For electrical work, this includes de-energizing equipment, following lockout and tagout procedures, and verifying the absence of voltage. As facilities today attempt to make the process of establishing an electrically safe work condition...
