Question

What happens in a zone of protection when a fault occurs?

A. The relay sends a trip signal to disconnect the faulted section.
B. The relay sends a fault location signal to the control center.
C. The relay adjusts the voltage and current levels to match the fault condition.
D. The relay activates an alarm to notify the operators of the fault.

Answer 1

In a zone of protection, when a fault occurs, the relay sends a trip signal to disconnect the faulted section.

Step-by-step explanation:

When a fault occurs in a zone of protection, the relay sends a trip signal to disconnect the faulted section. This is represented by option A. The purpose of a relay is to detect faults and respond quickly to protect the system from damage. By sending a trip signal, the relay ensures that the faulted section is isolated from the rest of the circuit, preventing further damage.
