Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

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- ....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):-
(C ....etc

INDUSTRIAL FAULT INDICATION SYSTEM WITH OVER VOLTAGE OVER TEMPERATURE USING ANALOG TO DIGITAL(ADC) CONVERTERS
Aim:
To design a fault indication system with over voltage over temperatue
BLOCK DIAGRAM:
Description:
To measure the voltage, current, and resistance we need to design analog circuits. These analog circuits measure these three parameters and ready to corresponding outputs.
The outputs of these analog circuits are to be connected ADC, ....etc
