CURRENT TRANSFORMER AND METHOD FOR CONVERTING A CONDUCTOR CURRENT FLOWING IN AN ELECTRICAL CONDUCTOR TO AN OUTPUT SIGNAL |
摘要 |
A current transformer arrangement, and method, include a current sensor for producing a sensor output voltage that is proportional to the input current flowing in a conductor; a first processing branch including a voltage calculating device for calculating the effective voltage value of the sensor output voltage; a second processing branch including a polarity detecting device having an input terminal connected with the current sensor output terminal to produce a polarity signal having one polarity when the conductor input current is either an alternating current, a hybrid current, or a direct current flowing in one direction, and the opposite polarity when the conductor input current is a direct current flowing in the opposite direction; and a multiplier device for modifying the effective voltage value to produce a signed effective voltage having a polarity corresponding with the polarity of the polarity signal. A modifying circuit modifies the signed effective voltage. |
