Advantage of STP over UTP Cable

Shielded twisted pair cable (STP) can reduce crosstalk with proper installation and maintenance. STP cables can resist signals from passing through the route coating and entering nearby wires by accident because of the special cable constructive.  Here this post gives information about what are the advantages of STP over UTP to better understand this topic.

Benefits or Advantages of twisted pair cable:

  • It is the least expensive medium of transmission for short distances.
  • It is relatively easy to implement and terminate.
  • It can be used to carry both pf the data analog and digital data.
  • It turn are less likely to cause interference themselves.
  • It is flexible and lightweight.
  • It is easy to set up and install.
  • Less susceptible to electrical interference caused by nearby equipment or uses of wires.
  • If the portion of twisted pair cable is damaged it does not affect the entire network.

Drawback or disadvantages of twisted pair cable:

  • Attenuation is very high.
  • It offers poor noise immunity as the result signal distortion is too much more.
  • STP called shielded twisted pair cable is more difficult to connect to a terminating block.
  • Being this cable is thin in size and they are likely to break easily.
  • Some transmission is limit.
  • Susceptible to noise and interference.
  • It supports lower bandwidth as compared to other media. It supports 10 Mbps up to a distance of 100 meters on a 10 base-T.
  • It supports lower bandwidth as compared to other media.
What are the Benefits of STP over UTP?

STP stands for shielded twisted pair cable. It is one type of twisted pair cable. It is basically similar to the UTP. It is similar to  UTP in which the wire pair are twisted around each other. Here this post gives the advantages and disadvantages of shielded twisted pair cable (STP) are listed below.

Difference Between Networking and Telecommunications

Telecommunication and networking both require different mediums of data transmission. The causes of the defect are completely different although slightly related. networking has its advantages with it as resources and data sharing are concerned. 

The main key difference between networking and telecommunication are listed below:
  • As we know that telecommunication can be defined as the transfer of data or information through a distance in the form of electromagnetic signals to one other receptive end while networking refers to the process of interconnecting devices in one main system mainly known as the server. 
  • Networking is mainly carried on through a physical medium like using some cables, wires, some other useful wires, and atmosphere at a very small range while telecommunication data is transferred through electromagnetic receptive devices like radios, phones, or television in the form of text, video, image, and sound.

Why induction motor is widely used in industry?

First, let us understand the basic key features of an induction motor:
  • It is easy and simple and rugged construction.
  • It is a low cost and minimum maintenance.
  • High dependability and sufficiently high proficiency.
  • Needs no additional starting motor and necessary not to be synchronized.

Some of the key points that why induction motor is widely used in industry?

  • The induction motor is a singly excited motor whereas the synchronous motor is a doubly excited one. 
  • The induction motor is cheaper than a  synchronous motor.
  • The induction motor is a self-starting motor, whereas the synchronous motor is not a self-starting motor 
  • Induction motor robust in construction and it can also work in any dusty environment. DC and the synchronous motor can't work industry and need regular maintenance.
  • synchronous motor and DC motor, these cannot work in a harsh environment whereas  Induction motor can.
  • When the coming to efficiency, the upper hand is for the synchronous motor but the starting mechanism adds up extra cost so even though a less efficient induction motor is implemented. 
  • As we know that the Dc motor has to use brushes, the synchronous motor has slip rigs where induction motor doesn't have, So reduced losses, efficiency due to o frictional lossless would be present.
  • The main requirement in the industry is to operate the motor at different loads and different speeds to drive mechanical load so this induction motor is the best to choose in the industry just because it has so many types of speed control whereas the synchronous motor always runs at synchronous speed.

                      • This motor is a highly efficient motor. The efficiency of the induction motor is varying from 85 to 95%.
                      • The maintenance of an induction motor is very less compared to the DC motor and synchronous motor.
                      • The working of an induction motor is very simple and unique. 
                      • The construction of an induction motor is robust and also sturdy.
                      • In this motor, only the AC source requires to operate. It does not require DC excitation like the use of a synchronous motor.
                      • In this motor, the speed variation from no load to rated load is very less.
                      • The induction motor is famous for its durability. This makes it the ideal machine for many of the uses. This results in the motor run for many years with no cost and maintenance.
                      • Due to the absence of brushes, there are no sparks in the motor. It can also be operated in hazardous conditions.
                      • Unlike synchronous motors, a 3 phase induction motor has high starting torque, good speed regulation, and also reasonable overload capacity.

                      Disadvantages of induction motor:

                      • The power factor of the motor is very low during light load conditions.
                      • During light load conditions, it operates at a very low power factor. 
                      • It has low efficiency.
                      • Single-phase induction motor is not self-starting.  It requires some auxiliary for stating.
                      • This motor cannot use in such applications where the uses of high starting torque is necessary like traction and lifting weight.
                      • The change in the speed of the motor is very low loading different loading conditions, so the speed control of IM is difficult.
                      • The speed of the motor is very low during different loading conditioned so, the speed control of the induction motor is difficult.

                      Advantages of polyphase system over single phase system

                      Advantages of the polyphase system:

                      • More power can e transmitted y the polyphase transmission system using the same amount of conducting material.
                      • Polyphase motor has a more uniform torque than the single-phase motors output torque is pulsating in nature.
                      •  In the case of induction motor polyphase induction motors are self-starting and more efficient ut single-phase induction motor is too self-starting.
                      • The output of 3 phase machine is always greater than the single-phase machine of the same size.
                      • A polyphase transmission line requires less conductor material a single-phase line for transmitting the amount of power at the same voltage.
                      • Polyphase motor has a uniform torque where most of the single-phase motor has pulsating torque.
                      • Per the unit of output, the polyphase machine is very much cheaper.
