High Voltage Busbar Protection
Author: Velimir Lackovic
A well-designed electrical protection system should cover all components against possible faults. Line protection concepts, such as overcurrent and distance arrangements, satisfy this requirement, even though short circuits in the busbar zone are cleared following a time delay. However, if unit protection is used for feeders and plants, the busbars are not inherently protected.
Although the risk of a short circuit happening on modern metal clad equipment is relatively low, it cannot be completely dismissed. The damage to a substation resulting from one short circuit event can be substantial, up to a total overall loss by fire. Severe damage would likely result in widespread and prolonged power disruption.
Upon successful completion of this course, engineers will be able to address the most important This course is suitable for electrical engineers with a desire to understand the fundamentals of high voltage busbar protection. It cover key technical concepts, design arrangements and protection methods. high voltage busbar protection arrangements and principles and appropriate application.
