8.1.2 Accuracy Specification Available Tests
184.108.40.206 R Test
The accuracy is based on the test conditions chosen to measure the winding resistance, and is given as:
AT = AR +AC+AV+AI
AT is the total accuracy (%)
AR is the basic relative accuracy (%)
AC is the calibration accuracy (%)
AV is the correction for voltage level (%)
AI is the correction for current level (%)
The value of AR is given in the table in section 1.1 of this chapter.
The values of the other factors are given below.
AV = 0.03% + (0.01% / VM)
AC = 0.2%
AI = 0.03% + (0.01% /IM)
VM is the measured voltage (V)
IM is the measured current (A)
