Explain the operation of the protection system on a three phase transmission line in the event of a given common fault. Fuses, circuit breakers, over current relays and under voltage relays are used as protection devices to protect transmission lines, generators, transformers and loads on a 3 phase network. Describe the operation of such protection system in the event of the following faults: a.Phase to phase fault b.Phase to neutral fault
And got the following answer:
Ideally, a phase to phase fault would trigger opening of at least one phase. Phase to neutral would cause the affected phase to open. They might also reclose a few times. Fuses open on overcurrent, and usually have a melt curve approximately similar to the wire they protect. Circuit breakers can reclose. For small molded-case breakers, it is usually manual. Large substation breakers might reclose automatically, or by remote control Overcurrent relays sense too many amps going through a wire, and trigger a circuit breaker, disconnect, or interrupter of some type. Undervoltage relays sense low voltages (such as due to a short circuit) and may work together with overcurrent relays to build a more accurate picture of where a short might be, and which lines need to be isolated.
The 3 phase relay function incredibly properly with distinctive applications which are certain to energy distribution and protection. The relays come with wide adjustment ranges having a scale that is definitely easy to read either in three or four digits based on the model. These 3 phase relay assist in growing the flexibility of your applications, lessen the all round energy and upkeep costs. You can find relays which are used for general purposes which come in reliable designs with quick replacement selections. And you will discover models that are utilized for industrial applications and heavier duty applications that work on substantial loads. These goods are created to meet the lifetime industrial control requirements on the applications.
Their latest solutions would be the Time counter, Timer Delay, 3 phase relay, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and various others. The web-site presents a detailed description of each and every model in several categories of 3 phase relay couplings and sensors. These solutions are very beneficial for high-risk applications. The 3 phase relay are also offered with options like various timing ranges and functions. The company is at present looking for agents and dealers who can market and sell their factory made products. They may be often on a lookout for building new and much more reputable solutions based on the needs and needs on the industry.
