    Fault analysis is conducted by DISCOM Engineers for the following purposes

    1. Locate faults
    2. Know  the cause,
    3. Determine if protective equipment is operated properly,
    4. Methods to implement in order to prevent the fault from occurring in the future

    Faults are abnormal states of the distribution network, usually associated with open circuits or short circuits or insulation breakdown between two or more points.

    Faults can be either temporary or permanent.

    Examples of temporary faults include the insulation breakdown by the interaction between the components and external agents (lightning strikes, wind, transient tree contacts, etc.) for a short period of time.

    Examples of permanent faults are insulator damage by flashover, underground cable breakdown, and surge arrester damage.

    Faults and their effects

    Effect of Fault

    • Danger to Operating Personnel
    • Loss of Equipment
    • Disturbance in the Interconnected Active Circuits
    • Electrical Fire

    Protection in Distribution Network

     If we are able to disrupt or break the circuit when a fault occurs, it reduces the considerable damage to the equipment and the system.

    fuses, circuit breakers and relays

    I hope that you got to know about the different types of faults in distribution systems. Thanking you for your valuable time spent on the article. Furthermore, please write your feedback in the comment section below related to the power system.
