Line protection, distribution, and backups refer to a set of measures and equipment used to protect electrical power systems from damage or disruption. Line protection is used to prevent damage to electrical transmission and distribution lines from overcurrent, overvoltage, and other electrical faults. Distribution is the process of transmitting electricity from the point of generation to the point of use, typically through a network of power lines and transformers. Backups are systems and equipment that are used to provide backup power in case of an outage or other disruption to the main power supply. This can include backup generators, batteries, and other sources of standby power. These measures and equipment are important for ensuring the reliability and availability of electrical power.
