NDB LCI – Live Cable Identification System – Medium Voltage

NDB LCI – Live Cable Identification System – Medium Voltage

The LCI helps in identifying energized electricity distribution power cables.

  • The LCI-E transmitter is previously connected to the secondary side of a distribution transformer to identify the medium voltage distribution cable located anywhere between the transformer and its source. The LCI is used on isolated distribution cables.
  • The equipment helps in identifying the right cable before cutting off the voltage prior to an intervention allowing thus to save time and money. It can also help in identifying a three-phase circuit by the identification of one of its conductors.
  • The LCI is composed of two main parts:
  • A transmitter, which drains electric current at a specific frequency that can only be detected on the cable section between the source and the transmitter’s termination point (transformer). Detection is possible on high-load cables.
  • A detector, which identifies the current that has been drained by the transmitter.
    The detector uses a magnetic sensor located at the tip of the enclosure and filters out network harmonics.
  • Specifications:

  • Efficient technique that eliminates the need for interpretation and all false identifications
  • Current transmission by forced drainage
  • Transmission on live cables
  • Transmission on high-load cables
  • Easy to operate and read
  • Connects to low voltage
  • Easy to connect
  • Safe to use
  • Detection by digital processing
  • High-resolution detection frequencies
  • Filtering out of network frequencies and their harmonics
  • High resolution detection frequencies
