Course description

In High Voltage Busbar Protection, you'll learn ...

  • The primary objectives of busbar protection
  • Common reasons why busbars are left without dedicated protection
  • An understanding of the differential system response to transient currents which allows busbar protection systems to be used with confidence in their fundamental stability
  • The various types of busbar protection schemes

Length: 44 pages

The protection arrangement for an electrical system should cover the whole system against all possible faults. Line protection concepts, such as overcurrent and distance arrangements satisfy this requirement, even though short circuits in the busbar zone are cleared after a certain time delay. But where unit protection is used for feeders and plants, the busbars are not inherently protected.

It is a fact that the risk of a short circuit happening on modern metal clad equipment is insignificant, but it cannot be completely dismissed. Nevertheless, the damage resulting from one short circuit may be huge, up to the overall loss of the substation by fire. Severe damage or destruction would possibly end in widespread and prolonged supply disruption.

This course is written for electrical engineers with a desire to understand the fundamentals of high voltage busbar protection. Presented details cover key technical concepts, design arrangements and protection types. Upon successful completion of the course, you will understand the most important high voltage busbar protection arrangements and principles and appropriate application.
