28) A voltmeter having a F.S.D. of 150 V, and a sensitivity of 2.5 kQ /V and internal resistance of 375 kQ is used to measure voltage V1 as shown in circuit. Determine (a) the true value of voltage V1, and (b) the measured value of voltage V1 with voltmeter between A and B. 65 kS2 A 70 KS2 B 150 V

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. Prote…

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 condi…

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).
