Overview of the Auto Recloser on Electrical Distribution Network

Auto Recloser is a critical component in electrical distribution networks that plays a crucial role in ensuring power continuity and protecting electrical equipment. In the event of a fault or disturbance, such as a temporary short circuit or momentary overcurrent, the auto recloser acts as an automated switch that opens and closes to isolate the fault and restore power supply quickly. The recloser is used in overhead power lines as a protective device, basically, it is used for electrical protection. These devices are used in overhead lines, distribution systems so that they can prevent or interrupt faults. The auto recloser is a protective device that would automatically trip and reclose for a preset number of times. The auto recloser is composed of a relay that would automatically close the recloser after clearing the fault. By using the recloser we can improve the continuity of the service, due to the ability of the recloser to restore the line power automatically after clearing the temporary faults. What are temporary faults? On medium or high-voltage lines, most trouble occurrences (faults) are temporary – such as lightning, windblown tree branches or wires, birds, or rodents – and will, by their very nature, remove themselves from the electric line if the power is shut off before permanent damage occurs to the lines. Examples of temporary faults include the following: • Windblown conductors touching one another • Lightning surges flashing over an insulator • Birds, reptiles or small animals bridging between an energized line and grounded surface • Tree branches touching energized lines • Switching surges that flash over an insulator Based on statistics and observations, the need for a trip-and-reclose function was readily recognized. If the line could be tripped open momentarily, then a subsequent reclosure very likely would be successful because, by then, the cause of the fault would be gone. Thus, the automatic circuit recloser, in providing this trip-and-reclose function, virtually eliminates prolonged outages on distribution systems due to temporary faults or transient overcurrent conditions.
