What does SCADA stands for:

• Supervision Center and Data Association

• Supervisory Control and Digital Association

• Supervision Control and Digital Acquisition

• Supervisory Control and Data Acquisition

In a basic SCADA system, which component is the interface between Field Devices and Control Center:

• FIELD DEVICE

• CONTROLLER

• HMI

• None of the above

What does RTU stands for:

• Remote Terminal Unit

• Relay Terminal Unit

• Remote Termination Unit

• Relay Termination Unit

In a basic SCADA system, which component provides operators real-time view of the remote devices:

• FIELD DEVICE

• CONTROLLER

• HMI

• None of the above

Identify SCADA Component item number 5 in the below diagram:

• UPS

• Remote Terminal Unit

• Control Center

Identify SCADA Component item number 6 in the below diagram:

This bus configuration consists of two main buses, both normally energized. Ele

ctrically connected between the buses are two breakers, and between these two

breakers is a termination.

• Ring Bus

• Single Bus

• Breaker and a Half

• Double Breaker – Double Bus

This bus configuration consists of two main buses, both normally energized. Electrically connected between the buses are three circuit breakers, and between each two breakers is a termination (middle breaker is shared by the two terminations).

• Ring Bus

• Single Bus

• Breaker and a Half

• Double Breaker – Double Bus

What type of bus configuration does the diagram show?

• Ring Bus

• Single Bus

• Breaker and a Half

• Double Breaker – Double Bus

The following are advantages of double breaker – double bus, which one is NOT?

• Isolation of either main bus for maintenance without disrupting service

• Isolation of any circuit breaker for maintenance without disrupting service

• Two circuit breakers are required for each circuit

• No interruption of service to any circuits from bus fault
