DC Current Sensors for Revenue-Grade Metering 2018

A recent report by the US Electric Power Research Institute (EPRI) predicts that by 2020, the DC distribution market will account for 50% of the total load, as the use of microgrid and other digital loads increases globally. However, for use in conjunction with existing AC distribution systems, it is necessary to convert AC power […]

J&D’s IDCS-U Series is Patented by Minimizing the Position Error that occurs in the diameter of the current sensor when wiring conductors.

Advanced open-loop Technology is based on six hall elements, Nickel-alloy core and a zero-drift operational amplifier IC. This minimizes error characteristics from the operating power supply or magnetic field. The IDCS-U Revenue-Grade current sensor from J&D meets the accuracy class of 1.0 (including conductor positioning error) according to IEC 61869-2 standard. Please feel free to […]
