Application of Electrical Technology - Assignment ExampleIn industrial applications, the switchgear is constructed with high-voltage circuit breakers and they may be lined-up together with the transformers in one unitized substation (USS). Switchgear de-energize loads in order to allow work to be done and also to enable clearing of faults downstream power systems. In the construction of protection relays, the current coil of the relay is connected to the secondary current coil of the transformer. Moreover, the secondary voltage coil of the transformer is connected to the voltage coil of the protection relay. When a fault occurs in the circuit feeder, an increased mmf of a current coil of the relay is triggered. The increased mmf closes the normally open contact of the relay that in return closes and completes the DC Trip Coil Circuit. The mmf of the Trip Coil initiates a tripping mechanical movement on the circuit breaker that causes it to isolate the fault.A sub-station refers to a part of an electrical generation, distribution, and transmission that that performs the function of voltage shifting from high to low and vice versa. A power plant refers to an installation that is used for the production of electricity while a power equipment refers to any equipment that is supply by electricity.A ring is an electrical wiring technique that enables the use of wires of smaller diameter than the ones used in the radial circuit, but of equivalent lend current. On the other hand, feeders refer to a set of electric conductors that transmit power from the primary distributor centers to secondary distribution centers or branch-circuit distribution centers.An closing off transformer is installed between an AC power source and medical grade equipment in order to protect patients and staff from electric shocks in case faults occur out-of-pocket to the defectiveness of a medical grade equipment or use of a non-medical grade.
