High-Precision Current Transformer
Phase shift (or phase error) and current error (or amplitude error) are critical for electricity measurement accuracy when miniature current transformers are used. For example, when primary current is 5% of rating, the upper limit of phase shift is 8′ for 0.1 class CT, and 4′ for 0.05 class CT. Xianyu’s high-precision current transformers have high linearity over the whole current range, and low temperature dependence. We can provide DC immune current transformers, in which composite cores are used; or AC miniature current transformer, when DC tolerance is not required.
