Solution

In digital relays, relay algorithms are stored in the relay's memory or microprocessor.

Here are the steps:

  1. The digital relay is a type of protective relay, a device designed to trip a circuit breaker when a fault is detected.

  2. The "brain" of a digital relay is a microprocessor. The microprocessor executes the relay algorithm, which is a set of rules that determine how the relay should respond to certain inputs.

  3. The relay algorithm is stored in the memory of the microprocessor. This memory could be ROM (Read-Only Memory), RAM (Random Access Memory), or flash memory, depending on the specific design of the relay.

  4. When the relay is in operation, the microprocessor continuously reads data from its inputs, processes this data according to the rules defined in the relay algorithm, and sends commands to its outputs based on the results of this processing.

  5. Therefore, in digital relays, relay algorithms are stored in the relay's memory or microprocessor.
