SOPD Emergency Response & System Restoration Procedures 3

Question 1

A 'hot line tag' differs from a 'clearance' in that a hot line tag:

Accepted Answer

Only cautions workers that a line is energized and in service — it does not de-energize it

Answer

A hot line tag advises workers that the equipment is energized; unlike a clearance, it does not guarantee a de-energized state and requires linemen to use live-line techniques.

Question 2

What is the purpose of a 'restoration priority list' maintained in an EOP?

Accepted Answer

To pre-determine the order in which loads and elements are restored to minimize outage duration and protect critical facilities

Answer

Restoration priority lists pre-define the sequence for energizing critical loads and system elements, ensuring hospitals, water pumping stations, and backbone transmission are restored first.

Question 3

During a major disturbance, an operator receives conflicting SCADA readings on a breaker status. The safest assumption is:

Accepted Answer

Treat the breaker status as unknown and use field verification or secondary indicators before acting

Answer

When telemetry is unreliable, operators must treat equipment status as unknown and verify via phone with field personnel or use secondary indicators such as current flow and voltage to determine true status.

Question 4

Which NERC standard specifically addresses the requirements for Transmission Operator Emergency Operations?

Accepted Answer

EOP-001

Answer

NERC EOP-001 establishes requirements for Transmission Operators to have documented emergency operations plans covering abnormal system conditions.

Question 5

A generator on black start duty fails to start. The system operator should:

Accepted Answer

Activate the alternate black start unit identified in the restoration plan

Answer

Emergency restoration plans require at least one alternate black start resource so operators can pivot immediately if the primary unit fails to start.
