Protective Relays could be characterized as circuit managers with varying degrees of supervisory and control capabilities depending on the complexity and criticality of the circuit. They are designed to recognize abnormal or fault conditions, and to isolate the affected portion or the electrical system. Not only does this allow the unfaulted portion of the electrical system to continue to function normally, but it diminishes the impact of the faulted portion of the system. Changes to power system circuits and the coordination of protective devices can change due to age, loading, environmental impacts, new construction, etc. It is therefore critical that these devices function properly and are appropriately coordinated when they are called into action.

Relays are often utilized in electrical facilities as isolated switches or protective devices for various electrical equipment. Due to the mechanical operation of relays, the contacts are prone to contact degradation, so it is important to regularly test for the electromechanical, electronic and protection schemes to ensure safe and reliable operation, and to avoid a faulty relay system acting up during critical operations. To assess relays and protections schemes, consider investing in a relay test set or a power system simulator.
The Doble F6150e Relay Testing System offers the ability to perform in both;
Relays take abuse during normal operation, so it is important to always check their condition. Regular checkups will negate problems before they worsen, or even start.

Electromechanical Protective Relays are usually attached to medium voltage circuit breakers to detect abnormalities in the current flowing within the electrical system.
The function of a protective relay is to detect abnormal power system conditions and initiate appropriate actions, such as the tripping of a circuit breaker.
