What is Protective System?
The term “protective system” in electrical engineering describes a group of components and procedures intended to prevent damage to electrical machinery, circuits, and systems from overloads, short circuits, earth faults, and other external sources.
A protective system’s major goals are to ensure employee safety, avoid equipment damage, reduce power outages, and preserve the electrical system’s integrity. In protective systems, protective devices including surge arresters, fuses, circuit breakers, and relays are frequently used to identify anomalous conditions and promptly separate malfunctioning portions of the electrical network.
Functions of Protective System
Below we listed some functions of Protective System in Electrical Engineering –
- Fault Detection: Detect abnormal circumstances including overloads, short circuits, earth faults, and voltage swings.
- Isolation: Isolate the problematic piece of the electrical network as soon as possible to avoid equipment damage and to ensure that electricity is delivered to unaffected locations.
- Safety: Keep individuals and property safe against electrical risks like electric shocks, fires, and explosions.
- Equipment Protection: Interrupting fault currents and abnormal situations can help to protect electrical equipment such as motors, transformers, generators, and distribution panels.
- Emergency Response: Provide maintenance professionals and operators with alerts, alarms, and diagnostic information to help them respond to emergencies more effectively.
