1.D47. (1e:1.D32) Resistors can be easily purchased with power ratings (the maximum power dissipation before they burn up) of W, +W, ±w and 1W. The lower the power rating, the less expensive the resistor. You are asked to analyze the circuit below to specify the power ratings of each resistor with the goal of minimizing the cost of the circuit, but also making sure that none of the resistors will go "poof". You are also asked to make sure that if the user accidentally reverses either of the two batteries that no resistor will fail. 100 N 9 V 133 N 6 V - 200 N Figure 1.60: The circuit for problem D47.
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).
