Powering Data Centers

Question 1

What are Surges?

Answer 1

Sudden, small increases in voltage beyond the standard level (e.g., 120V in the US)

Question 2

What are Spikes?

Answer 2

Short-lived voltage increases, often caused by short circuits, tripped breakers, or lightning

Question 3

What are Sags?

Answer 3

Brief decreases in voltage, usually not severe enough to cause system shutdown

Question 4

What are Undervoltage Events (Brownouts)?

Answer 4

Prolonged reduction in voltage, leading to system shutdown

Question 5

What are Power Loss Events (Blackouts)?

Answer 5

Complete loss of power for a period, potentially causing data loss and damage

Question 6

What are Line Conditioners?

Answer 6

Stabilize voltage supply and filter out fluctuations

Question 7

What are Uninterruptible Power Supplies (UPS)?

Answer 7

A device that provides emergency power to a system during power source failures

Question 8

What is a Generator?

Answer 8

A machine that converts mechanical energy into electrical energy for use in an external circuit through the process of electromagnetic induction

Question 9

What is a Power Distribution Center (PDC)?

Answer 9

Central hub where power is received and distributed to all systems in the data center
