摘要
method of reducing errors przeku0142adnika pru0105dowego is that determined the difference value of primary current and secondary current converted into the original przeku0142adnika, that difference is a measure of the error przeku0142adnika, and then strengthens the difference a result is obtained, which carries out the power, powering the additional length of the winding core przeku0142adnika.the current through the winding core, which carries out domagnesowuje additional przeku0142adnika, thereby increasing the secondary przeku0142adnika and thereby reducing the difference of primary and secondary currents converted into the original przeku0142adnika resulting in decreased error p rzeku0142adnika.system for reducing errors przeku0142adnika pru0105dowego contains a primary and secondary currents difference value converted into the original przeku0142adnika (pir, which are connected in series with two entry uzwojeniami primary and secondary nawiniu0119tymi spinal (rmg przeku0142adnika).solution the difference currents (pir) transducer is connected with the front arm strengthening (cw), which, in turn, exit is powered winding additional length to the core przeku0142adnika (rmg) in such a way that the output current amplifier (cw) floating by the additional winding domagnesowywau0142 core przeku0142adnika (rmg).
