Switch redundancy automated system type LRW-H5
Application
- 110 kV switchgears with one bus-bar system.
Advantages
- one multi-purpose device dedicated for all possible switchgear systems with up to 5 cubicles
- two criteria for the switch position: current, switch
- two independent activation inputs
- two switch-off circuits
- two independent supply circuits
- configuration and settings made by means of PC
- possible co-operation with one- or five ampere transformers
- disruption recorder (all currents recorded)
- software by ENERGOAPARATURA
- LINUX operating system
