Limitations of fuse

There are some limitations of fuse are listed below:
  • The heat produced by the arc may affect some of the associated switches.
  • Action is by melting of fuse so this could be rather slow in some situations.
  • During short circuit or sone overload in the circuit once fuse blows off replacing of fuse takes time. During this period the circuit lost power.
  • Need replacement when blows off by overcurrent.
  • It has a low speed.
  • You have to keep a replacement handy in case fuse is blows.
  • Fuse can't bear a surge current in the case of motor starting.
  • Fuse is not suitable for overloading.
  • Fuse has a low breaking capacity.
  • Fuse is not protected to the circuit against under-voltage.
  • It can be replaced by an oversized fuse by a novice to ensure it does not blow next time. This can damage the equipment it is supposed to protect.
  • The current-time characteristics of a fuse cannot always be correlated with that of some protected device.
  • When the fuse is connected in series it is difficult to discriminate the fuse has a significant size difference.
  • The protection of fuse is not reliable.
  • On the heavy some short circuit in the system, the discrimination between the fuses in series cannot be obtained unless there are considerable differences in the relative sizes of the fuses will be concerned.
  • Considerable time is lost in rewiring or replacing a fuse after the operation.

Difference between MCB and fuse

What is a fuse?

The most common overcurrent device is a fuse. A fuse is merely a small length of wire. Fuse is always placed on the phase wire.

What is MCB?

MCB called Miniature circuit breaker,  MCB is designed to operate on overload current and they can be used as protection devices for the individual circuit. MCB can also provide magnetic fault protection and short circuit protection.

 MCB can be changed over the switch needs to be pushed backed to the On position. While in the case of the fuse, the whole wire will have to be replaced first and there are also have some disadvantages of a fuse like it has low breaking capacity, and it has slow compared to other circuit breakers. So here this post gives information about several advantages of MCB over fuse or we can say that why we have to use MCB better than a fuse.

The main key difference between MCB and Fuse are given below:

  • As we know that relay is a switch, it is not usually meant to open under fault conditions and would likely fail if done so while in the fuse is a fault protection device. If a short circuit is developed, a large current will flow, and the fuse link will melt, causing the circuit to open.
  • All the relay is considered to be a fuse, but all the fuse are not considered as a relay.
  • A relay can be reset and put back into service after an overload but in the fuse needs to be replaced after every fault.
  • Fuse is mainly used for protection to our equipment so that when the high current passed through fuse more than its limit it will melt and protect our appliances but while in case of the relay it is used to accurate the high power appliance from the low power triggers. We can make fuse out of relay using a circuit but can do it in the fuses. 
  • A fuse protects from the overload and relay is a control device that uses a small amount of electrical current to control a larger amount or current.
  • Relay work with DC supply but in the fuse did not need DC supply.
  • A fuse is used for breaking the circuit while the relay is used for sensing purposes.
  • MCB is sensitive to vibration and movement, which can cause the switch to trip for reasons unrelated to an electricity overload, but in the fuse does not influence by vibration nor movement was secured in the fuse housing and was not rely on the switching mechanism as MCB.
  • MCB is costlier than the fuse unit system.
  • MCB, quick restoration is possible by just switching operation, resettable but infuse quick restoration of supply can not be possible because fuse must be replaced once blown.
  • Handling MCB is more electrically safe than a fuse.

The different type of main application of LiFi are listed below:

EMI sensitive environments

Li-Fi enabled lighting will allow high data rate connectivity for each and every passenger. This process will allow connectivity at all times without creating electromagnetic interference with sensitive radio equipment on the flight deck. 

Underwater communication

Radio waves are quickly absorbed in water, preventing underwater radio communication, but light can penetrate for large distances. Therefore LiFi can enable communication from driver to driver, driver to mini-sub, driver to drilling, etc.

Traffic light

LiFi can be used to provide drivers with traffic and also to be weather updates as they wait at the traffic for light. This also eliminates the problem of getting critical traffic updates to drivers who are already on the road.

The Military

Unlike WiFi, LiFi is confined to a small range. As light does not penetrate walls, data transmitted over LiFi can be limited to a small area such as a tent. This makes LiFi great for use by the military even in remote locations as the data can't be intercepted by the outside hackers. 

Augmented reality

This system will exhibit in museums and galleries that are illuminated with specific lighting. LiFi enabled lighting can provide localized information within the light. This means that visitors' cameras or mobile phones can be used to download further information regarding the object being viewed from the light that illuminates the exhibit.

Safety environments

In the explosion hazard environment, the use of electrical equipment, including mobile phones, is generally greatly restricted. The use of LiFi, will to the pass data simplify the configuration of data networks in such an environment and it can enable new systems to enhance security in these real environments.

Localized advertising

 By using shop display lighting as a LiFi broadcast channel used and, it is possible to transmit the advertising information on the goods being viewed, as well as say special offers and coupons. This will allow the merging of the high street and online shopping experience, and provide a novel retail business model to emerge. 

Sensitive data

 Hospitals are specific cases of an environment where both EMI sensitivity and security of data are issues. LiFi can enable the better deployment of secure networked on medical instruments, and patient records.

Indoor navigation

 Be identifying each light it is possible to provide a smart means of navigating through the urban environment. The identification of each code would of each code be linked to a specific location.

 Connectivity

 Our homes already have lighting widely installed. So the uses of the LiFi system enabled lighting will transform the various applications that can be envisaged, that not only the interconnection of devices, such as televisions computers and HiFi but also connecting ordinary domestic appliances, such as fridges, washing machines, vacuums.

Advantages and disadvantages of fuse

Fuse is the cheapest protection device in all over the electrical circuit against the short circuit overloading of the circuit. Fuse is used in low and moderate voltage applications where the frequency operations not expected or where the use of a circuit breaker is uneconomical. It is a basic metal wire or thin strip which has the property of a low melting point which is inserted into the electrical circuit as a protective device. The fuse will protect the machine or electrical equipment against excessive currents. Here this post gives information about the advantages and disadvantages of fuse to better understand how to fuse is used in an electrical circuit.

Advantages of Fuse:

  • Fuses are the cheapest form of protection.
  • The fuse element change very easily.
  • The fuse needs zero maintenance.
  • It affords the current limiting effect under short circuit conditions.
  • Its operation is completely automatic and requires less time as compared to circuit breakers and no complexity is envolved
  • Most of the fuses are self-protecting and also they extinguishing the arc.
  • When we use the small size of the fuse element impose a current limiting effect under short circuit conditions.
  • Its inverse time-current characteristics enable its use for overload protection.
  • Fuse has the ability to interrupt enormous short circuits without producing noise, flame or smoke.
  • Easy to removable for replacement without any damage to coming into contact with a live part.
  • The operation time of fuse can be much smaller than the operation of the circuit breaker. It is the primary protection device, against the short circuits.

  • Considerable time is required in replacing a fuse after the operations, while the circuit breaker can be used multiple times.
  • It can't bear a surge current in the case of motor starting.
  • Fuse has not protected the circuit against under-voltage.
  • The fusing elements of the fuse are exposed to air, hence it is oxidized. Therefore the resistance of the element is increased and produced heat when the current passing through it.
  • There is a possibility of renewal by the fuse wire of the wrong size.
  • The current time characteristics of a fuse cannot always be correlated with that of the protective device.
  • When fuses are connected in series it is difficult to discriminate against the fuse unless the fuse has a significant size difference.
  • Fuse does not respond to the high voltage it only cares about current flowing and is not likely to melt and save the house in case of a direct lightning strike.
  • Accurate calibration of fuse wire is impossible, as longer fuse operates earlier than one of shorter length.

How do hard disk and floppy disk differ?

In the floppy disk, the data is recorded in the form of magnetic dots on spots on tracks while in hard disk the data is stored as magnetic spots on tracks that concentric circles on the surface of disks but both of having the same technology. There are have some similarities like that both use magnetism to store and read the data. They also have both use a spinning platter read by a horizontally moving read head. Here this post gives information about how do hard disk and floppy disk differ?

Some key points to differentiate between them.

  • First most important that hard disk is faster while floppies are very slow in comparison to the hard disk.
  • The hard disk is huge in capacity but in floppy disk have very low capacity.
  • Storage disk in hard is made of metal material while in the floppy disk are made of plastic.
  • The life span of the hard disk is very long in comparison to floppies.
  • Hard disks are sealed units. They can survive dust or moisture while floppies can not.
  • A hard disk can have multiple platters inside it while floppies can have one only.
  • All the parts of the hard disk are enclosed in a single unit. Just plug and play. Floppies need the drive to run them. You can call it a floppy disk drive or reader too.
  • A hard disk can have multiple platters inside it while floppies can have one only.
  • All the parts of a hard disk are enclosed in a single unit. Just plug and play. Floppies need the drive to run them. You can call it a floppy disk drive or reader too.
  • You will not find floppies anywhere nowadays. They are obsolete. Hard disks are in use and survived the times bravely and gracefully. Still holding the front.

Differentiate between Floppy Disk and Hard Disk

As we know that, the hard disk is a mechanical drive with multiple disks capable of storing 8  Terabytes if not more worth of data. The disk drive is capable of reaching read and write speeds of 300 MB/s. While in the floppy disk is a small plastic storage device typically capable of no more than 1.44Megabytes or storage. It is also now rather outdated thanks to the advancement in today's technologies. Generally, the floppy disk is capable of reaching 250-300 bit/s read/write speed. The hard disk is a magnetic disk on which you can store computer data while diskette is random access, a removable data storage medium that can be used with personal computers. Based on the respective working conditions advantages of floppy disk and advantages of a hard disk are different also have some advantages of Hard disk over floppy disk and limitations of the hard disk over the floppy disk. Here some difference between floppy disk vs hard disk to better understand this topic.

The main key difference between the floppy disk and hard disk are given below:

  • The hard disk is a circular piece of mylar or plastic-like material coated with iron oxide while the hard is a stack of few thin metal plates, usually coated, usually coated on both sides with magnetized material.
  • Hard disk has much more storage capacity than a floppy disk.
  • Slower access time while hard disk has faster access time.
  • In the floppy disk, the data is recorded in the form of magnetic dots on spots on tracks while in hard disk the data is stored as magnetic spots on tracks that concentric circles on the surface of disks.
  • The hard disk is the flexible disk is housed in a plastic jacket but in hard disk is flexible is housed in a metal jacket.
  • While use floppy disk the flexible disk is housed in a plastic jacket, hard disk is often called a fixed disk.
  • Floppy disk holds less data that is 1.1.4 MB, hard disks hold more data that is several GBs.
  • Floppy disk drive only begins rotating when they are required to read or write data, but in hard disk drive spin continuously. They start rotating when a computer is switched on.
