Why do we use high voltage?
High voltage is used in electrical systems to efficiently transmit electricity over long distances. By increasing the voltage, the current in the transmission lines is reduced, which decreases the amount of energy lost as heat due to conductor resistance. This allows for more efficient transmission of electrical energy from power plants to substations and eventually to end users. High-voltage transmission helps minimize energy losses and reduce the cost of electricity delivery.
Why is high voltage used for transmission?
Medium voltage is used in electrical distribution networks to bridge the gap between high voltage transmission and low voltage distribution. It is typically used in distribution systems in urban and rural areas to carry electricity from substations to local transformers or directly to industrial and commercial facilities. Medium voltage is applied in scenarios where the distance is not as great as for high voltage transmission, but where high voltage is still needed to efficiently manage power distribution.
Why is high voltage important?
High voltage does not refer to a specific amperage because it is a measurement of electrical potential, not current. The amperage associated with high voltage systems depends on the power transmitted and the specific design of the electrical system. High voltage systems are designed to handle a range of current levels, depending on power requirements and the capacity of the transmission infrastructure.
The energy is transformed into high voltage for long-distance transmission to reduce power losses. When electricity is transported at high voltage, the current in the transmission lines is lower, which minimizes thermal losses due to conductor resistance. By using high voltage, utilities can transmit large amounts of power over long distances more efficiently, reducing overall cost and improving power supply reliability.
High voltage is generally defined as voltages above 35 kV (35,000 volts). In different contexts, the exact threshold for what constitutes high voltage can vary, but it generally refers to voltage levels used in electricity transmission systems and substations. For example, transmission lines can operate at voltages of 115 kV, 230 kV or even higher, depending on power requirements and transmission distance.
