PLCC OVERVIEW :

PRESENTED BY BIMAL NANDA


PLCC Technology

PLCC system uses the same High Voltage transmission line connecting two sub-stations for telecommunication purpose too.
PLCC is used in all power utilities as a primary communication service to transmit speech, telemetry and protection tripping commands. This is economic and reliable for inter grid message transfer as well as low bit rate RTU signals.
The voice/data are mixed with radio frequency carrier (40-500kHz), amplified t ....etc

ABSTRACT
This paper deals with the implementation of power line
network in the field of electricity billing. In the present
scenario power line communication (PLC) is one of the
economical ways of communication of data. Even though
there are new methods of wireless communication methods,
practically it is very much time consuming to install such a
system, and also it is highly cost consuming method .But the
power lines which already exist and connect every household
in a particular area is more advantageous as it does not require
any ....etc

PLCC.



Outdoor equipment:-

1. Wave trap:- These are used for blocking the HF signals of PLCC entering into substation. Wave traps will allow only high voltage power signal of 50Hz frequency.

2. Line matching (LMU):- The output of PLCC is connected to the LMU then to the power lines to achieve proper impedance matching between PLCC equipment and power lines.

3. Capacitance voltage transformer/Capacitor coupling (CVT/CC):-
(CVT/CC) is connected betwe ....etc

pdf report of automatic active phase selector for single phase load from three phase supply

ABSTRACT: Phase absence is a very common and severe problem in any industry, home or office. Many times one or two phases may not be live in three phase supply. Because of this, many times, some electrical appliances will be on in one room and OFF in another room. This creates a big disturbance to our routine work. This project is designed to check the availability of any live phase, and the load will be connected to the particular live phase only. Ev ....etc

download the ppt on design and fabrication of tyre coupling pdf

ABSTRACT

Mild steel or wrought iron shaft are available in lengths varying from 6 to 10 meters, so as to make them handy and easy to transport. More lengthy shafts cannot be manufactured in a correct form to be used for power transmission. In engineering practice shafts of large lengths are required to transmit the torque which can be obtained by joining two or more shafts in order to obtain the required length. The joining of shafts is done by device is called as coupling.Tyre c ....etc
