Unit A (4)
Device that protects a transformer from being overloaded with current.
What is a circuit breaker?
Power loss affecting many customers over a large geographical area for a significant period of time.
What is a blackout?
Are interconnected and dispersed among high-voltage transmission lines and distribution lines.
What are substations?
An interruption or failure of electrical service that is unintentional and unexpected.
What is an unplanned outage?
Pipelines that supply local service areas.
What are distribution mains?
An electric current that reverses its direction at regularly recurring intervals.
What is alternating current?
a planned partial reduction in the voltage of electrical power service.
What is a brownout?
Is the third and final step in the electric power system.
What is the electric power distribution? (Distribution)
A specialized electric power meter that measures the amount of power consumed and has the ability to communicate information between the meter and a central communication system.
What is a smart meter?
Pipelines that connect distribution mains to individual service connections.
What are street mains?
Circuits that transmit lower voltages from the substation.
What are distribution circuits?
Meeting fluctuations in demand or matching generation to load to keep the electrical system in balance.
What is load balancing?
Are systems with a single power source for a group of distribution customers.
What are radial distribution networks?
Smart meter technologies that employ enhanced communication technologies that automatically measure and and report power usage information.
What is advanced metering infrastructure?
What are interstate pipelines?
The maximum amount of power a transmission line can carry without experiencing any heat-related deterioration.
What is a thermal limit?
created by the FERC to administer the transmission grid on a regional basis in a neutral manner.
What is a regional transmission organization?
This transformer has more turns in the primary winding than in the secondary winding.
What is a step-down transformer?
A system of remote assessment used to monitor and control the electrical transmission system.
What is supervisory control and data acquisition?
Pipes that connect the distribution mains to a customer's home meter.
What are individual service connections?
Reduction in voltage between the source and load in an electrical circuit caused by electrical resistance.
What is voltage drop?
A technology for transmitting electricity that uses special conductors designed to improve transmission capabilities.
What is high temperature superconducting?
Some substations have theses that is built with in the substation yard and contains switchboard panels, batteries, battery charges, supervisory control panels, meters, relays, and other control systems equipment.
What is a control house?
Mechanisms or systems that enable the strategic management of electricity consumption in response to supply conditions.
What is demand response?
The physical location where a local gas-distribution company receives natural gas from long-distance transmission pipelines.
What is a city gate station?
