Explain the metering techniques used for LT and HT consumer metering.
In power distribution systems, metering is essential for accurate measurement of electrical consumption and ensuring proper billing. There are two primary categories of consumers in power distribution systems based on voltage levels: Low Tension (LT) and High Tension (HT). Metering techniques for these two categories vary based on their operational requirements and the nature of their electrical consumption.
### LT Consumer Metering
Low Tension consumers typically operate on voltages less than or equal to 400V. These are generally residential, small commercial, and industrial consumers. The metering techniques used for LT consumers are relatively straightforward, as their power usage is generally low, and the infrastructure is simpler compared to HT systems.
1. Electromechanical Meters: Traditionally, electromechanical meters have been used for LT consumer metering. These meters function based on a rotating disc that is influenced by the current flowing through it. The speed at which the disc rotates is proportional to the amount of electricity consumed. ____ _______ _____ ____ _____ _____ ___ ______ __________ ______ __________ ______.
