Ru R1 Voltmeter R2 R3 V The RCL bridge seen in the picture is used to determine the resistance Ru (resistor under test). For the supply voltage V we can use: Either a DC or an AC power supply, as long as the voltmeter can handle this type of voltage. Only an AC power supply since we need to provide a certain Vrms with high accuracy for precise measurements. Only a DC power supply, since AC power supplies will provide bipolar voltages. The measurement cannot be performed, since RCL bridges should be made of resistors, capacitors and inductors connected together.
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).
