When a high voltage system insulation test value is suspect or recorded during an annual survey, a polarization index test is performed. What is the polarization index?
A
The polarization index is the ratio of the insulation resistance taken at thirty minutes to the insulation resistance taken at one minute.
B
The polarization index is the ratio of the insulation resistance taken at ten minutes to the insulation resistance taken at one minute.
C
The polarization index is the ratio of the insulation resistance taken at one minute to the insulation resistance taken at ten minutes.
D
The polarization index is the insulation resistance taken at ten minutes.
