INFORMATION

Description

  • Unit equivalent to 4 residual current protection networks. Features 4 independent programmable relays.
  • Four inputs for connecting the external toroidal transformers of the WGC / WGS series.
  • Super-immunised type-A relay with high-frequency current filtering and high immunity. True root mean square (TRMS) measure
  • Compact size: 3 modules
  • Features 5 independent programmable outputs (4 residual current tripping relays and 1 prealarm relay).

Applications

The CBS-4 multipoint residual current system associated with the WGC / WGS transformers offers smart residual current protection. Its design features guarantee maximum security and electrical service continuity, avoiding unwanted tripping. Viewing the instantaneous leakage value on the display, together with the prealarm indicators, makes it possible to obtain information on the status of lines to be protected, and to perform adequate preventive maintenance.
In addition, version CBS-4 C features RS-485 communications and, with the PowerStudio software, offers centralised supervision in real time, as well as keeping a log of historical data for future analysis.
