True or False: Power variations that can interfere with IT equipment operation are caused only by external factors.

The statement that power variations causing interference with IT equipment operation are due only to external factors is false. Power quality issues can arise from both external and internal factors.

External factors may include fluctuations in the utility supply, lightning strikes, or other environmental influences. Internal factors, however, can also significantly impact power quality. This includes but is not limited to demands placed by different types of equipment operating on the same circuit, harmonics generated by non-linear loads, and inherent limitations in the design of the distribution system within a facility.

Recognizing that both external conditions and internal system dynamics contribute to power variations is essential in understanding how to maintain IT equipment operability effectively. Given this comprehensive view of power quality issues, the correct response to the statement is indeed false.
