(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Supervisory Control and Data Acquisition system for monitoring and control.
SCADA
All‑Dielectric Self‑Supporting fiber cable used for communications only.
ADSS Fiber
A project performance metric that compares the value of work completed to the value of work that was planned to be completed by a given date.
Schedule Performance Index (SPI)
A disconnect switch operated remotely by an electric motor.
Motor‑Operated Disconnect
The substation at the opposite end of a transmission line.
Remote End Substation
An abnormal condition where electrical current flows along an unintended path, usually due to insulation failure, equipment damage, or contact with ground or another phase.
Fault
Buried conductors forming a low‑resistance grounding system.
Ground Grid
Bus connection that allows thermal expansion and contraction.
Expansion Connection
a device installed in a high‑voltage substation that blocks high‑frequency communication signals from entering substation equipment while allowing normal power‑frequency current to pass freely.
Wave/Line Trap
A bus configuration where breakers form a closed loop, improving reliability.
Ring Bus
This device steps down the current to a lower level current (less than 5 amps) suitable for a relay or meter input.
CT
Transfers electrical energy between circuits at different voltage levels using electromagnetic induction.
Power Transformer
Protects equipment from overvoltage surges caused by lightning or switching.
Surge Arrester
Supplies low‑voltage power to substation auxiliary loads.
Station Service Transformer
Fixed aluminum or copper bus supported by insulators.
Rigid Bus
Low‑voltage cable used for protection, control, and indication circuits.
Control Cable
Optical Ground Wire providing lightning protection and fiber‑optic communication.
OPGW
Occurs when one phase conductor contacts ground or grounded equipment. This is the most common type of substation fault and usually produces a large ground current.
Line‑to‑Ground Fault
A structure that anchors conductors at the end of a transmission line.
Dead‑End Structure
A device that collects data from substation equipment and sends it to a control center, and can also receive commands to control that equipment remotely.
Remote Terminal Unit(RTU)
A new substation project built on undeveloped land, where no existing electrical infrastructure is present.
Greenfield Station
Connects equipment to ground for safety during maintenance.
Ground Switch
Flexible conductors that connect rigid equipment and allow movement.
Jumpers
Happens when two phase conductors touch each other. These faults create high current levels and can cause significant equipment stress.
Line‑to‑Line Fault
Protection logic that operates backup tripping if a breaker fails to clear a fault.
Breaker Failure Scheme
Voltage difference between a person’s feet during a ground fault.
Step Voltage
Protection scheme that detects faults within the bus zone.
Bus Differential
Final drawing reflecting actual installed conditions.
As‑Built Drawing
Correct orientation of current transformer terminals for relay accuracy.
CT Polarity
A device used to automatically maintain the electrical voltage within a desired range by adjusting voltage levels as system load changes.
Regulator
Conductive bars or tubes that distribute power within a substation.
Buswork
Coupling Capacitor Voltage Transformer used for voltage measurement and communications.
CCVT
Condition where a current transformer cannot accurately reproduce current.
CT Saturation
Surface grounding mesh to reduce step and touch voltage.
Ground Mat
Vertical electrode driven into earth to improve grounding.
Ground Rod
A project performance metric used to measure cost efficiency — how well a project is performing compared to its budget.
Cost Performance Index (CPI)
Voltage between a grounded object and the ground surface a person is standing on.
Touch Voltage
Provides visible isolation of equipment but does not interrupt load current.
Disconnect Switch (DS)
Voltage or Potential Transformer that steps down voltage for measurement.
VT / PT
A gas that insulates between the active and non-active components of a substation and can drastically reduce the clearance distances.
Sulfur Hexafluoride (SF6)
A project that is built within, attached to, or replaces part of an existing, operational substation.
Brownfield Station
A Breaker connecting two buses or feeders.
Tie Breaker
A substation layout using three breakers to protect two circuits.
Breaker‑and‑a‑Half
A feeder supplied from a single source with no alternate path.
Radial Feeder
An auxiliary bus used to transfer circuits during maintenance or breaker outages.
Transfer Bus
Interrupts fault and load current to protect the system.
Circuit Breaker
A standard modular control building that contain protective relays and control equipment used to operate the substation.
