New staff training-Second class

Secondary Electricity Basics Training Notes Must begin with a thorough understanding of direct current (DC), alternating current (AC), phase-to-phase and line-to-line voltages. For any company that relies on electrical systems, this knowledge is critical to the generation, distribution and regulation of electricity.

Direct current is the flow of charge in a single constant direction. Batteries and electronic devices such as laptops and cell phones run on direct current. Alternating current, on the other hand, is constantly reversing direction. AC power is used in homes and buildings to run appliances and equipment.

Phase voltage is the potential difference between two points in an AC circuit, one of which is the wire and the other is the neutral point. On the other hand, line voltage refers to the potential difference between two points in an AC circuit, one of which is a wire and the other is ground.

To sum up, understanding the difference between direct current and alternating current, phase voltage and line voltage is an essential aspect of the basic knowledge of second-class electricity. It is critical for any business or company that relies on or creates electrical systems to have a solid understanding of these concepts to ensure they apply the correct safety standards and operating procedures.
