(ii) Calculate the inductance of a coil wound on a ferromagnetic cylinder of 2 mm diameter and 10 mm length. There are 200 turns on the coil and the relative permeability of the core is 600.
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).

In your own words, explain why the presence of a ferromagnetic
core increases the inductance of a coil.
Calculate the inductance of a coil wound on a ferromagnetic
cylinder of 2 mm diameter and 10 mm length. There are 200
turns on the coil and the relative permeability of the core is 600.
How does a real inductor differ from an ideal component?
The coil in (a) forms part of the switching mechanism of a relay
switch controlled by a transistor. The transistor produces a
current which can switch between 5 mA and zero over 1 μs.
Ignoring any losses, calculate the voltage induced by the relay
coil and say why this is problematic for the transistor.
What component can be added to the relay circuit to prevent the
problem observed in (b)(i)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F453e2dee-5bad-4d2e-a71f-6b8eeb7e8b02%2Ff63cd1e3-84ca-4178-907f-4d72c9447b45%2Fuzfybh6_processed.png&w=3840&q=75)
