These are three causes of outages.
What are trees, equipment failure, maintenance, lightning, wind, ice, weather balloons, animals, car crashes, and King Kong? (Name 3)
300
This is a device that reduces current to a measureable value in order for a relay to see the current on a line.
What is a Current Transformer (CT)?
300
This man publically electrocuted animals to show the dangers of alternating current.
Who is Thomas Edison?
400
This term refers to electrical potential difference (or electric tension or electric pressure).
What is voltage?
400
In a transformer, a higher number of coils will increase the value of this variable.
What is voltage?

During these kinds of studies, Transmission Planning performs contingency analysis and checks for overloads, voltage problems, and instability.
What are power flow studies?

In differential relaying, we use a principle called Kirchoff's law to detect and imbalance in the system. This law states that the sum of the currents in a closed circuit must sum to this number.
What is 0?

This physicist is credited for creating the first electrochemical battery in 1800.
Who is Alessandro Volta?
500
Q refers to this in the power equation P = (Q*V)/t.
What is electric charge (coulombs)?
500
This is the number of volts typically supplied to your home outlets.
What is 110V? (or 115V or 120V)
500
For SRP, the transmission system pertains to lines and equipment within this range of voltages.
What is 69kV - 500kV?

In an overcurrent relay, it is important that the relay responds quickly - but how quickly it responds is determined by this.
What is size of fault current? (the larger the current, the faster the relay will operate)
500
In 1885, Nikola Tesla began working for this company where he developed the AC power system.
