### Who uses ct scan?

A physician prescribes the study for a patient, a radiologist
authorizes and protocols the study, an x-ray technologist executes
the study. The physical "use" of the machine is done by the x-ray
technologist, but each of these persons can be said to use ct
scans. By the way ct scans are also used by veterinarians, and have
been used for archaeological pursuits (the study of Egyptian
mummy's.

### What is a class X current transformer?

Class X CTs are special CTs used mainly in balanced protection
systems
(including restricted earth fault) where the system is
sensitively dependent
on CT accuracy. Further to the general CT specifications, the
manufacturer
needs to know:
• Vkp - Voltage knee point
• Io - Maximum magnetising current at Vkp
• Rs - Maximum resistance of the secondary winding

### What is sine theta plus 2 cosine squared theta?

I shall use x instead of theta since I cannot be bothered to
paste it at each step.
sin(x) + 2*cos2(x) = sin(x) + 2*[1 - sin2(x)] = sin(x) + 2 -
2sin2(x) which cannot be simplified further.
