Key Concepts
- -- Low Tension Switchgear
- An assembly of devices for controlling, protecting, and isolating electrical circuits operating at low voltage levels.
- -- Earthing (Grounding)
- The process of connecting the non-current-carrying parts of an electrical system to the ground to prevent electric shock and ensure safety.
- -- Power Factor
- A measure of how effectively electrical power is being converted into useful work output; low power factor can lead to increased energy costs.
- -- Batteries
- Electrochemical devices storing electrical energy; can be primary (non-rechargeable) or secondary (rechargeable).
- -- Energy Consumption Calculation
- The process of determining how much electrical energy an appliance uses over time, usually measured in kilowatt-hours.
