Measurement bridge circuit for three-wire circuit, has standard resistors arranged in control unit, such that voltage is developed at one resistor corresponding to voltage drop at feeder lines, where drop is added to feeder voltage portion
Measurement bridge circuit for three-wire circuit, has standard resistors arranged in control unit, such that voltage is developed at one resistor corresponding to voltage drop at feeder lines, where drop is added to feeder voltage portion
The circuit has an electronic control unit provided as current source at an output of an amplifier unit (6), where source current of the control unit is propositional to a feeder line loss. Two standard resistors (R1, R2) are serially arranged in the control unit, such that a voltage is developed at the resistor (R2) which corresponds to voltage drop at feeder lines, where the drop is added to feeder voltage portion at a quarter bridge.
