The coil head has an arrow at the top that indicates the positive sign of the passing current.
Currents that flow in the opposite sign will measure as negative voltages in the HVCP
receiver.
WARNING REGARDING ISOLATION
Due to their non-conductive nature, the fiber optic cables provide excellent isolation between
probe head and receiver. However the probe head can and should be considered floating at
the same potential of the measured conductor. Thus the whole body of the HVCP probe head
including the metallic bayonet connectors can be at hazardous potentials.
It is advisable to install a voltage detector/indicator on the measured line that provides visual
and clear indication about the presence of potentially dangerous voltages. SAKER offers the
MVD and MVDH series of medium voltage presence detectors.
RECEIVER-OSCILLOSCOPE CONNECTION
A BNC-BNC cable is supplied to connect the receiver to a measuring oscilloscope. Use of a
good quality cable is recommended as it could affect the measurement.
