CB Watch 3
HV Circuit Breaker Monitoring Solution
Utility Asset Managers all know how critical their power transformers are and understand the risks and consequences of any failure. They are now focusing on the fact that high voltage circuit breakers are often just as critical. When a transformer problem is detected, protection relays and circuit breakers are relied upon to isolate it from the grid and a breaker’s “failure to operate” is not a palatable option.
Key Benefits
- Modern modular solution that fills diverse fleet monitoring needs with the same platform
- Can be factory fitted on new GE breakers or retrofitted to most types and brands
- Delivers reduced and optimized operating maintenance costs
- Enables condition-based asset replacement strategy
- Helps reduce costly SF6 gas releases to the environment
- Seamless communication with control or asset management tools and through web server HMI
Applications
The CB Watch 3 is suitable for most HV circuit breakers: live tank or dead tank, with ganged or independent pole operation. But it is also increasingly used on GCB (Generator Circuit Breakers), on HYpact and on the circuit breaker compartments of GIS (Gas Insulated Switchgear). The configuration chosen can be mounted inside the control cabinet (especially when factory fitted) or next to it in it’s own separate enclosure.
