  • Power Generation, Transmission, Distribution and Safety

    What About Transmission lines?Power Plant SafetyStart with Safety to Improve Your Bottom LineAfter the generation of power, it is transported using transmission lines. These lines are constructed between substations that are located at power generation stations and they are either underground or overhead supported by towers. Transmission lines have high voltages and send out large amounts of electricity over considerable distances. After the electricity comes from the generating station, the transmitted voltage is stepped up to a range of 115,000 to 500,000 volts. However, when it gets into a transmission substation, the voltage is reduced to 46,000 to 115,000 volts. One of the main hazards during the transmission of power is electrocution. If your employees don’t use the necessary protective gear or maintain the proper distances, serious injuries and even death can result. Falls can also occur during the maintenance of overhead lines or while working from bucket trucks or poles. The transmission system is connected to customer’s equipment by a distribution system.
