Question

Accepted Answer

The main function of LA in a substation is to protect electrical equipment from lightning strikes.

LA stands for Lightning Arrester.
It is installed in substations to divert lightning strikes away from sensitive equipment.
LA provides a low-impedance path for lightning current to flow to the ground.
It helps in preventing damage to transformers, circuit breakers, and other electrical devices.
LA operates by ionizing the air around it, creating a conductive path for lightning current.
LA can handle high voltage surges caused by lightning strikes.
It is designed to withstand multiple lightning strikes without failure.
LA is an essential component for ensuring the reliability and safety of the substation.
Example: If a lightning strike occurs near a substation, the LA will divert the lightning current to the ground, protecting the substation equipment from damage.
