Joe asked Anyone help with any information due to these 3 phase phase faults?

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 over and under voltage relay operate extremely properly with distinct applications which can be particular to energy distribution and protection. The relays come with wide adjustment ranges having a scale that’s easy to read either in 3 or 4 digits according to the model. These over and under voltage relay assist in increasing the flexibility from the applications, minimize the general power and upkeep costs. There are actually relays that are employed for basic purposes which are available in trustworthy styles with quick replacement selections. And you’ll find models which might be used for industrial applications and heavier duty applications that perform on big loads. These products are made to meet the lifetime industrial handle requirements in the applications.
Their most current items are the Time counter, Timer Delay, over and under voltage relay, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and a variety of other folks. The web page gives a detailed description of every single model in different categories of over and under voltage relay couplings and sensors. These products are incredibly valuable for high-risk applications. The over and under voltage relay are also obtainable with capabilities like various timing ranges and functions. The enterprise is at the moment seeking agents and dealers who can market and sell their factory created items. They are always on a lookout for developing new and more dependable items based on the desires and requirements on the sector.
