When is the best time for maintenance?
Condition-based maintenance enables users and maintenance teams to continuously supervise circuit-breaker conditions and performance trends, and to constantly manage the related warnings and faults. Thanks to ABB MyRemoteCare online condition monitoring solution, our service engineers suggest the right sort of maintenance at the best time for each asset by analyzing the acquired data. Historical data makes it easier to detect typical deviations from standard behavior over the years.
Where does the monitoring data come from?
When your switchgear is not equipped with the integrated diagnostic systems, sensors or intelligent electronic devices to collect the data about circuit breaker condition, ABB provides MySiteCare: a universal circuit-breaker monitoring and diagnosis device.
How to view and interpret the data?
ABB service engineers analyze the diagnostic data of the circuit-breakers in the remote mode and ensure that events are signaled. Maintenance officers can consult the decisions and/or actions planned by ABB experts via a user-friendly interface that displays faults by means of a traffic light: red, yellow and green. This signal indicates how serious the fault is, thus the probability of failure or impaired reliability and safety of the monitored equipment.
Can any breaker be monitored?
When the circuit breaker is already operating, it is advisable to inspect and/or service the device before installing MySiteCare for the purpose of:
- checking the state of the circuit-breaker and restoring, as far as possible, the original conditions
- preventing failures or impaired performance of the circuit-breaker by replacing excessively worn components and by installing the specific upgrade kits for each circuit-breaker
- assessing the real conditions of the circuit-breaker so as to configure MySiteCare in the appropriate way.
Is it easy to implement?
Installation of MySiteCare on each panel does not involve any changes to the circuit-breaker, the protection relay or switchboard.
The predictive diagnostic algorithms are configured by ABB’s qualified technicians when the monitoring system is commissioned: the parameters concern the relevant circuit-breaker and its operating status.
