Step 4: Calculate the Thevenin equivalent voltages between points a and b (VTh(a,b)) [mV] and between points b and c (VTh(b,c)) [mV]. Use the circuit diagram of figure 1. Keep Switch 1 and Switch 2 open. Step 5: Calculate the voltage across resistor R5 (VR5) [mV]
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).
Step 4: Calculate the Thevenin equivalent voltages between points a and
b (VTh(a,b)) [mV] and between points b and c (VTh(b,c)) [mV]. Use the circuit diagram of figure 1. Keep Switch 1 and Switch 2 open.
Step 5: Calculate the voltage across resistor R5 (VR5) [mV] and the
voltage across resistor R6 (VR6) [mV]. Use the resistance values from step 3 as follow R5 = RTh(a,b) and R6 = RTh(b,c). For the calculation of VR5 close Switch 1 and leave Switch 2 open. For the calculation of VR6 close Switch 2 and leave Switch 1 open. Use the circuit diagram of figure 1.
Step 6: Calculate the maximum power absorbed by resistor R5 (PR5) [μW] and the maximum power absorbed by resistor R6 (PR6) [μW]. Use the resistance values from step 3 as follow R5= RTh(a,b) and R6 = RTh(b,c).
