Question 1

What is a Diesel Generator

Answer 1

: Provide emergency power by converting diesel fuel into electricity. They are crucial in data centers for ensuring uninterrupted power during outages.

Question 2

UPS (Double Conversion)

Answer 2

This type of UPS continuously converts incoming AC power into DC power and then back to AC. It’s used in data centers to protect against power anomalies.

Question 3

Automatic Transfer Switches (ATS) and Static Transfer Switches (STS)

Answer 3

ATS are used to switch power sources automatically. STS are faster and used for high-speed switching between power sources.

Question 4

Chillers and Cooling Towers

Answer 4

Both used to Remove heat from the water used in the data center’s cooling systems. Chillers cool the water, and cooling towers release the heat outside.

Question 5

Pumps

Answer 5

Circulate the cooling medium (like water) in the cooling system of the data center.

Question 6

Hot and Cold Aisle Containment

Answer 6

This design minimizes mixing of hot and cold air, improving cooling efficiency in data centers.

Question 7

Power Usage Effectiveness (PUE):

Answer 7

A ratio that measures how efficiently a data center uses energy; specifically, how much of the energy is used by the computing equipment in contrast to cooling and other overhead.

Question 8

Real Power vs. Reactive Power:

Answer 8

Real power is the capacity of the circuit for performing work in a particular time. Reactive power is the power that flows back and forth between the source and load, which contributes to the magnetic and electric fields.

Question 9

Power Factor

Answer 9

A measure of how effectively incoming power is used in your electrical system and is defined as the ratio of real power to apparent power.

Question 10

Transformers:

Answer 10

Electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction, used to step up or step down voltage levels.
