Disclosed are an apparatus for measuring a coil current of a hydraulic valve, and a method for measuring a coil current thereof. The apparatus for measuring a coil current of a hydraulic valve, according to the present invention, comprises: a first coil current measurement unit for receiving a first coil current control signal from a coil current control device to measure a coil current flowing through a coil of the hydraulic valve, during an off operation section of the hydraulic valve; a coil current feedback unit for feeding the coil current back to the coil current control device, so that the coil current required for the braking is compensated from the coil current control device, based on the measured coil current; and a second coil current measurement unit for receiving a second coil current control signal, from the coil current control device, to measure the compensated coil current, supplied from the coil current control device, during an on operation section of the hydraulic valve. |
