Quiz 2: 5%

Which one is the BEST meaning of telecommunication?

• the process of converting information between two area

• the process of control the communication network

• the process of exchanging information between two or more distant locations

• the process of energy flow between two distance

Which one is NOT CORRECT for Point-to-Point Connections

• Easy to implement

• No complexity in addressing the node

• Cost effective

• Large number of communicating entities

Types of Communication Systems (you can tick more than one answer)

• Point-to-Point Connections

• Point-to-Network

• Network of Many Nodes

• Network of Network

• Network of Many Networks

Data transmission techniques include...

(You can tick more than one)

• Public telephone

• Fibre Optics

• Frequency Control

• VHF Broadcast Radio

What is GSM?

• Global Mobile Communication

• General Mobile Communication

• Great Mobile Communication

Power Line Carrier Communication (PLCC) is commonly used for

• voice communication,

• telemetry and telecontrol

• GSM purpose

• SCADA purpose

Which one is RIGHT about Coupling Capacitor (CC)?

• The carrier equipment is connected to the transmission line through CC which is of such a capacitance that is offers low ( 1/wC) to the carrier frequency but high reactance to power frequency.

• CC blocks the carrier frequency signal to enter the carrier equipment and allowing the power frequency currents to enter the carrier equipment.

• To reduce impedance further, low inductance is disconnected from the network with CC to form a resonance at carrier frequency

Power Line Carrier (PLC) is used for:

• Carrier Communication

• Carrier Telemetering

• As a relay

• As a transmitter

The identical electronic equipment NOT include:

• Transmitter unit

• Breaker Unit

• Relay Unit

• Receiver Unit

Why communication in Power System is important?

• It is important as all the generating plants are primarily in towns and located near their loads.

• The cost of the power system generation is depending on the communication in power system

• As the power station control rooms and substation control room's staffs should have to got something to work with

• The successful operation of a power system depends to the ability to communicate from one location in the system of other locations involved in the operation.
