### Asset Description:
Air Compressor: A device that converts power into potential energy stored in pressurized air. It is commonly used to power pneumatic tools and equipment.

### Conditions:
- ABS[Pressure Pressure Setpoint] > 10 PSI

### How long the conditions were met:
Met for 2 Hours

Given the above detected conditions, what should NOT the operator look for?
A. Mis-sized equipment
B. A new leak in the air lines
C. Too many or too few compressors are running


# Answer

Answer: A. Mis-sized equipment

Guidance Rationale: 
Given that the air compressor has maintained a pressure deviation greater than
10 PSI from its setpoint for a duration of 2 hours, this indicates a persistent
mismatch between desired and actual pressure levels. Such a deviation could be
caused by air leaks in the system or by having too many or too few compressors
running relative to the demand. However, the sustained pressure behavior
suggests that the equipment is capable of delivering the required output, which
implies that equipment sizing is likely appropriate for the operational context.

In contrast, mis-sized equipment would typically manifest as an inability to
maintain pressure consistently or as cycling inefficiencies—neither of which is
implied here. Therefore, the operator should not focus on equipment sizing as
the cause. Instead, investigating a new leak in the air lines or the number of
compressors running would be more relevant. A new leak could cause a drop in
pressure, while an imbalance in the number of compressors could lead to either
excessive or insufficient pressure, both of which align with the observed
conditions.
