  • Types of Transformers - Megger

    2020-7-29 · Great question. An inter-tie transformer helps connect AC networks of various voltages to each other, which is a really important feature in a power network. Typically, your autotransformers are going to be the largest rated power transformer on your transmission system – operating with a pretty balanced and constant load.

  • Electrical grid - Wikipedia

    2 days ago · An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of: power stations: often located near energy and away from heavily populated areas; electrical substations to step voltage up or down; electric power transmission to carry power long distances

  • Power factor - Wikipedia

    2021-9-11 · In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. A power factor of less than one indicates the voltage and current are not in phase, reducing the average product of the two.
