3 Instrument Description
The VPLog-i-R AC current sensor, based on a Rogowski coil, that measures AC currents up to
1600A true-rms on a single phase power cable.
The sensor has a modbus interface for communication.
The sensor has an indication LED. This blinks when modbus communication is ongoing.
Each sensor has a unique serial number and is delivered with a calibration certificate and report.
The following figure shows the module dimensions. The area/diameter of the loop formed by the
measurement coil (light gray on the figure) is 65mm?.
The hole (?1.5mm) in the plug can be used to seal the device.
The irregularity in the loop between the top and bottom coil end, is compensated by a unique circuit
that compensates for this error. So there is no additional error due to the mounting of the coil in a
plane perpendicular to the power cable or not.
