ROGOWSKI’S COIL WARNING!
Rogowski’s coil (accessory RC-V400-100) have been designed for accurate nonintrusive measurement of AC,
pulsed DC or complex waveforms.
To use in an appropriate way,
- wrap the ring on the conductor so that the arrow symbol (stamped in the ring) is oriented in the same
direction of the current in the conductor
- make sure that the connections are performed properly: the white output wire is positive (+), the brown
wire is the negative (-).
WARNING!
Connect the shield of the Rogowski’s coil at negative (-) (one of the terminals 14 or
16 or 18 or 22).
Terminals 14, 16 18 and 22 are internally connected
Voltage Terminals Max 600V
The Rogowski
has polarity. Wrong direction can’t measure correctly (for example
negative current value instead of positive)
If there is some distortion by harmonic or waveform, it may not measure correctly.
Separate the wiring (strong electric part) of the measured voltage input terminal
(operating power supply terminal) from the CT cable. It may not satisfy the accuracy
due to noise.
The S203RC-D input full scale factory calibrated is only the +-100mV for 1000A.
Others full scale configurable are +-50 mV or +- 200mV for better measure precision,
but in this cases you must manually set the currents user calibration values.
