WebThe lightning arresters are used to protect the power system from high voltage surges. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage, and protects the equipment installed in parallel. WebOct 2, 2024 · The matter of grounding systems in substations is vital. The main functions of a grounding system are: Provide the neutrals of generators, transformers, capacitors, and reactors a connection to the earth. Offer a low impedance path to the earth for the currents coming from ground faults, lightning rods, surge arresters, gaps, and related devices. prof philo trappes
Lightning arrester Definition & Meaning Dictionary.com
Lightning arresters are used to protect electric fences. They consist of a spark gap and sometimes a series inductor. Such type of equipment is also used for protecting transmitters feeding a mast radiator. For such devices the series inductance has usually just one winding.
