EA Technology CableData Collector

EA Technology has launched an instrument for identifying defects in live cables of distribution voltages. The CableData Collector works by testing for partial discharge (PD) activity - small discharges that result in damage to the cable, and if left unattended will lead to insulation failure.

The instrument quickly detects PD activity in live cables by measuring radiofrequency currents. It works with most types of single- and three-phase insulated cables at distribution voltages, up to several kilometres in length.

Information about PD activity is recorded by the CableData Collector hardware and can be sent to EA Technology for expert analysis. Alternatively, users can purchase EA Technology’s software package to perform their own data analysis. In either case, they will have access to clear reports on cables affected by PD activity and recommendations for remedial action.

CableData Collector instruments are supplied as complete, ready-to-use kits, with radiofrequency current transformers (RFCTs), cabling, USB-powered data collection unit and carry case, together with optional software, training and factory technical support. Kits are also available for rental, or EA Technology engineers can provide cable testing as a site service.
