DC immune Current transformer for electricity meter
TOPRO DC immune Current transformer (DC immune CT) are used in electricity meters, under the influence quantity
with DC and even harmonics in AC current circuit. We adopted high quality
amorphous alloy and nanocrystalline core for DC immunity Current transformer,
with good linearity and high accuracy up to Class 0.2, Class 0.1 and 0.05. The DC tolerance is less than 3%，Conform to standard IEC62053-21.
