The burden of a protective relay is the power

  • The burden of a protective relay is the power consumed by the internal circuits of the relay, including the sensing elements, signal processing circuits, and output relays.
  • This power is required for the protective relay to operate and carry out its protective functions.
  • It is important to properly account for the burden of a protective relay in the design and selection of protective relays, as it can affect the overall power consumption of the protection system and may impact the performance of other system components.
  • Minimizing the burden of a protective relay wherever possible is essential for ensuring efficient and reliable system operation.
