What is the legacy grid?

• A grid that has a two way communication source.

• A system of hardware and software tools that utility

  companies use to monitor and gather real-time data and

  interact with smart electrical devices

• Equipment and infrastructure that rely on mechanical

  devices to provide quality energy to customers and to

  protect the system from failure.

• Equipment and infrastructure that incorporate the internet

  and radio technology for communicating and coordinating

  between devices and with system control

What does dead-break mean?

• Designed to safely connect or disconnect without load

  current

• Designed to safely connect or disconnect with load of less than 50 amp of current.

• Designed to safely connect or disconnect with load

  current present.

• Designed to safely connect or disconnect automatically without a technicians assistance.

What two types of fuses are there?

• Gas and Vacuum

• Expulsion & Current-limiting

• Blown or not blown

• S&C and Southern states

What is SCADA?

• Equipment and infrastructure that incorporate the internet

  and radio technology for communicating and coordinating

  between devices and with system control

• Equipment and infrastructure that rely on mechanical

  devices to provide quality energy to customers and to

  protect the system from failure

• A system of hardware and software tools that utility

  companies use to monitor and gather real-time data and

  interact with smart electrical devices

What does the term "self-healing" mean when referring to the grid.

• The ability to reroute power without malfunctions without manual intervention.

• The poles and wires will grow back without a lineman's help and we're all out of a job.

• The grid can clear a temporary fault and maintain power.

• Equipment and infrastructure that rely on mechanical

  devices to provide quality energy to customers and to

  protect the system from failure

Should a lineman know the rated load capacity of any switch before operating and why?

• No, the system will balance the load out once the switching has taken place.

• Yes, to ensure the transformers will have enough power to serve the customer.

• Yes, to ensure the switch can handle the load that is present.

• No, due to the fact that switching will be temporary, the switch can be overloaded.

The smart grid can isolate and sectionalize areas of

the power grid for what purposes?

• SCADA & Data Acquisition

• Coordination & Control

• Protection &

  Self-healing

• Money & Respect

What does a Loadbuster do?

• It protects from voltage surges such as lightning etc...

• It quenches the arc normally created when interrupting

  load current.

• It reroutes the overcurrent to ground to keep the lights on.

• It re-energizes the line in an attempt to clear a temporary

  fault
