Angle tolerance
Angle tolerance
Angle correction for cable converter in two operating points F1/I1 and F2/I2:
Angle correction F1, F2
(for resonant-grounded system)
Current values Ι1, Ι for angle correction
for sensitive 1 A transformer
for sensitive 5 A transformer
for normal 1 A transformer
for normal 5 A transformer
Measurement tolerance
sensitive
non-sensitive
Note: Due to the high sensitivity, the linear range of the measuring input Ι
transformer is from 0.001 · Ι
tion can no longer be guaranteed.
