Protection System
A system that protects electrical systems from faults by isolating the problematic part from the remainder of the system, preventing power from being cut from healthy elements, improving system dependability and efficiency is the protection system. Protection devices are the equipment that are utilized to implement the protection system.
Predictive Maintenance System
Predictive maintenance technologies are designed to assist in determining the state of in-service equipment so that maintenance can be scheduled. Predictive maintenance is the application of information; proactive maintenance approaches examine the condition of equipment and anticipate when it should maintain. The purpose of predictive maintenance is to forecast when equipment will fail (depending on a variety of parameters), then prevent the failure through routine and corrective maintenance.Condition monitoring is the continual monitoring of machines during process conditions to maintain optimal machine use, which is necessary for predictive maintenance. There are three types of condition monitoring: online, periodic, and remote. Finally, remote condition monitoring allows the equipment observed from a small place and data supplied for analysis.
Preventive Maintenance System
To maintain the equipment and materials on a regular basis in order to maintain those running conditions and reduce unnecessary shutdowns due to unexpected equipment failure is called Preventive Maintenance (PM).

Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get remaining
sub-part solved please repost the complete question and mention the sub-parts to be solved.
The components of a basic electromagnetic relay are a solenoid, which is a coil of wire wound around a soft iron core, an iron yoke, which offers a low resistance channel for magnetic flux, a moveable iron frame, and one or more sets of contacts. Reed, solid-state, and electromechanical relays are the three primary categories. The electromagnetic induction theory underlies relay operation. An electromagnetic field is created around an electromagnet when some current is delivered to it. The relay is operational in the above image. DC current is applied to the load using a switch. The iron core and copper coil in the relay function as an electromagnet.
