- Page 2 DIMENSIONS INTRODUCTION The HVCP from is a novel Rogowski current probe that provides high voltage isolation via fiber optic cables. Not only is this approach advantageous from the voltage isolation point of view but is also immune to typical radiated interferences and capacitances created when using long coaxial measuring cables.

COMPATIBILITY The HVCP probe requires an external oscilloscope, digital multimeter, power analyzer or a recording device. In case an oscilloscope is used the bandwidth of the channel should be limited to 20MHz to avoid excess noise in the measurement.

Page 11: Care And Maintenance
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 can be at hazardous potentials. -

Up to 15m can be configured PERFORMANCE VERIFICATION HVCP probes are shipped from Saker and both probe head and receiver are tested as a system and adjusted to meet the AC current accuracy and frequency specifications. Accuracy between emitter and receiver is automatically maintained by two internal precision voltage references and a software algorithm. - Page 13 CERTIFICATIONS The HVCP probe complies with EC Directive 2014/30/EU for Electromagnetic Compatibility. Compliance was demonstrated to the following specifications as listed in the Official Journal of the European Communities: EC/EN 61326-1:2021 EMC requirements for electrical equipment for measurement, control, and laboratory use: Electromagnetic Emissions: IEC/EN 55011/A1:2016 Radiated Emissions 30-1000 MHz.
