The circuit in Figure 7 is a regular household system of a single-phase three-wire circuit that allows the operation of both 120 V and 240 V, 60 Hz appliances. The circuit is protected by fuses. The fuses have negligible resistance and burn out when the circuit draws more current than its amperage rating. i. Calculate the currents I, I and I ii. A momentary short circuit causes Fuse A to burn out (Le, it behaves like an open circuit). Calculate the new current I Fuse A (100A) Fuse E (30 A) 120/20 V 12020 v Lamp Motor Fuse B (100 A) 120 0 Fuse C (15 A) 100 j5 Ω | Fuse D (15 A) Figure 7 550 Q Heater

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).
