WEBINAR: BRUSH CONDITION MONITORING CONVERSATION


WHY MONITOR BRUSHES?

View the webinar here.

The number one cause of ring fires is short brushes. The main objective of Brush
Condition Monitoring (BCM) is to stop forced outages caused by short brushes.
The system allows plants to better plan their maintenance schedules. Plants only
pull brushes when needed. This enables a safer work environment, since personnel
have less interaction with a highly reactive environment. BCM grants plants the
ability to look at the condition of brush rigging remotely, sending brush
analytics wirelessly to a remote controller.

Real – World Example:
Catastrophic events, such as ring fires, can happen between regular periodic
checks of the equipment. The image to the right shows what can happen when
measurements are taken 24 hours apart. BCM would have given plant personnel
advanced notice that the unit was failing, and could have alerted the plant,
ultimately preventing an expensive forced outage.


INSTALLATION PROCESS

Brush Condition Monitoring is a simple and minimally invasive installation,
usually completed within one eight hour shift. Sensors fit easily inside
EASYchange brush springs wirelessly talking to the monitors and plant personnel.
If plants already own EASYchange holders, BCM installation is even easier and
quicker.


HISTORIAN

Data is available within the historian through PI, and within InsightCM. Plants
choose how they want to be alerted and when. They can choose which analytics and
alarm levels to use, and the data can be color coded for personnel to quickly
look over. The power of the system lies within the ability to send real – time
information to the historian so personnel can look at it remotely. This has been
especially important in allowing those working from home to know the health of
their generators.


CUSTOMER TESTIMONIAL

Joe Riebau, a Senior Engineering Manager with Exelon Power, has overseen the
implementation of Brush Condition Monitoring at several Exelon Power sites and
integrating their systems into their DCS.

What led to the decision to implement BCM at Exelon Power?
Within 30 months there were four brush rigging events at two Exelon sites. Each
site had a water ingress issue causing damaged brushes, rigging, and collectors.
We attempted to put a Band-Aid on the trouble spots using duct tape, but it
wasn’t successful. After one of the sites had a flashover event, we knew it was
time for a change. That’s when we implemented Cutsforth™ Brush Condition
Monitoring.

How has your company integrated BCM in your DCS?
We have the system integrated into PI and DCS. We set up email alerts, and
engineers can monitor and receive alerts from home using PI, which is especially
helpful during Covid times.

What are your company’s long – term plans to install BCM at additional sites?
We are looking to install BCM at additional sites. Monitoring gives plants the
capability to detect potential failures, and decreases anxiety of brush rigging
events.

CONCLUSION

Brush Condition Monitoring allows plants remote access to vital brush health
information. This advanced detection allows plants to better schedule their
maintenance and manpower hours, while decreasing maintenance costs.
