Study Notes
Relay Types
- Digital relays can detect faults as they develop, providing early warning and allowing for prompt action to prevent damage.
Reclosure in EHV Systems
- The aim of reclosure in EHV (Extra High Voltage) systems is to re-energize the circuit as quickly as possible after a fault has been detected and cleared.
Reclosure in Low Voltage Systems
- In low voltage systems, up to two reclosures are allowed before the circuit is locked out.
Test your knowledge on protective relays and their ability to detect and mitigate electrical faults. Learn about the unique capabilities of the Buccholz relay in detecting incipient faults. Explore the different types of faults and their development in transformer tanks and low voltage systems.
