The portable combined CDS is used as universal dielectric diagnostic system on PE / XLPE insulated cables as well as paper insulated cables worldwide. It combines the known methods of Isothermal Relaxation Current measurement (IRC-Analysis) and Voltage Return Method (RVM-Analysis) for aging and deterioration diagnostics. Due to the low charging voltage of the measurement the CDS works absolutely non destructive.
Key Benefits:
Absolutely non-destructive condition evaluation of PE / XLPE / paper-oil insulated cable systems
Simple operation and automatic measurement procedures
Three-phase parallel measurement for current and voltage – duration of a complete measurement 1 hour
Extended dynamic range for IRC measurement for long cable segments
Measurement of charging current during formation
Improved filters
Extended capacity of internal rechargeable battery for serial measurements
Extended formation voltage up to 5 kV – suitable for diagnosis on HV cables
