Dc Resistance Current Transformer Cores - China

When using current transformers, the accuracy of measurement determined

by the primary current amplitude error ( contrast) and phase error (

difference) .

In medium accuracy without the requirement of DC component

of electric meter, the absolute value of these two is very low, but it

can be compensated through the relevant correction circuit.

DC component

of current transformer is different, because the difference of its phase

difference is large and stable.

The special characteristic of amplitude

error is relatively small.

There is an energy measurement error.

The

error changes with the primary current.

If the phase difference don' t

compensate, it cannot be applied in high perceptual load.
