What functionality does a Digital Protective Relay (DPR) typically provide?

A Digital Protective Relay (DPR) is primarily designed for the detection of electrical faults within an electrical network. This includes the ability to monitor electrical parameters and recognize conditions that may pose a risk, such as overcurrent, undervoltage, or phase imbalances. When a fault is detected, the DPR can initiate protective actions, such as disconnecting the affected section of the network to prevent damage to equipment and ensure safety.

While a DPR can be integrated with other systems to potentially provide data storage, real-time analytics, or user interface enhancements, these are not its primary functions. The core purpose remains fault detection, which is crucial for maintaining the integrity and reliability of electrical systems, making this the correct answer.
