Description
- Unit equivalent to 8 earth leakage protection networks. 8 independent programmable relays available
- 8 inputs to connect the external toroidal transformers of the WG / WGP
- Superimmunized Type A relay with high frequency current filtering and high immunity. Monitoring in true root mean square (TRMS)
- Size adapted for 8 modules
- 9 independent programmable outputs (8 earth leakage trip relays and 1 pre-alarm trip).
Applications
The CBS-8 earth leakage station associated to the transformers of the WG / WGP Series allows an smart earth leakage protection. Its design features guarantee maximum security and continuity of the electrical service, avoiding unwanted tripping. Showing the value of the leak instantaneously on the display with the pre-alarm indications provides the information about the state of lines being protected, thus allowing the implementation of an adequate preventive maintenance approach. In addition, RS-485 communications are used with the Power Studio software, which allows the centralised supervision of the system in real time, with a record log that can be analysed later on.
