Protective relay testing is usually divided into three categories: acceptance testing, commissioning, and maintenance testing. Acceptance or evaluation testing determines whether a relay is appropriate for use on a specific protection application within a power system. Distance Relays: Measure impedance to detect faults in transmission lines, aiding in fault location and isolation.

According to the properties of the material that are used to modulate the light beam, modulators are divided into two groups: absorptive modulators and refractive modulators.

Key types include Overcurrent Relays for detecting excessive currents, Differential Relays for internal fault protection, and Distance Relays for transmission line protection. In this guide, we will explore the different types of line protection relays commonly used in high-voltage transmission and distribution systems. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
