  • Page 9: Operator Safety

    EA Technology CableData Collector Operating Manual 1365/L/01/1 Operator Safety  The CableData Collector is designed to detect partial discharge sources in High Voltage (HV) cables. If no discharges are detected this does not necessarily imply that an item of HV cable is discharge free. Discharge sites often have dormant periods and insulation structures can fail through causes other than those attributable to partial discharges.

  • Page 10: Warnings & Tips

    Do not insert a network cable into the Ethernet Socket, it is currently unsupported and not functional. Tips  The unit contains no user serviceable parts, always return to EA Technology or your local distributor for service and repair.  The CableData Collector unit is designed to function with a mains frequency signal present, which may occur because of imbalanced phases.

  • Page 11: Introduction

    EA Technology CableData Collector Operating Manual 1365/L/01/1 Introduction Non-Intrusive Detection of Partial Discharge Activity General Partial discharges are electric discharges that do not completely bridge the electrodes. The magnitude of such discharges is usually small however; they do cause progressive deterioration of insulation that may lead to eventual failure.

  • Page 49: Using The Cabledata Collector

    EA Technology CableData Collector Operating Manual 1365/L/01/1 Using the CableData Collector Using the RFCT for online Partial Discharge (PD) tests on medium voltage power cables is relatively straightforward and very safe, as the current transformer is simply clamped around the earth cable using its split core as illustrated in Figure 67. This method can be used on- line without disconnecting cables or switching off supplies to customers.

  • Page 51: Cable Partial Discharge (Pd)

    EA Technology CableData Collector Operating Manual 1365/L/01/1 11.1.3 Cable Partial Discharge (PD) The power cables being tested for a PD event must be earthed via an earth strap to allow measurements to be made of PD between phase and earth. Once a PD event has occurred through the electrical insulation of a cable, a set of pulses both equal in magnitude but opposite in polarity are seen on the line conductors and the earth conductor.

  • Page 52: Rfct Connection Requirements

    EA Technology CableData Collector Operating Manual 1365/L/01/1 11.1.4 RFCT Connection Requirements The RFCT detects the occurrence of a partial discharge between the line conductor and earth by monitoring the condition of either of the three connection methods mentioned below. The connection methods are shown in Figure 69. Connections can be made: By monitoring the earth cable only (figure C), this is the preferred connection method.
