Grounding brush holders
Morgan Advanced Materials’ Electrical Carbon business announces the
availability of its grounding brush holders, designed for stability and reliable

dissipation of current to prolong bearing life. he grounding brush holders
have a contact drop of less than 1 volt due to their high quality silver-graphite
brush.
DC motors applied on static drive systems and AC motors on adjustable-

speed drives can experience voltage spikes that can cause current to low
through the motor shaft bearings. Over time, these currents cause pitting of
the bearings and eventually bearing failure.
Condition monitoring system
Introducing grounding brushes to the motor provides a low resistance path
to ground, in parallel with the bearings, and can eliminate this issue, without Renewable NRG Systems (RNRG) has completely redesigned its

Improved alert management allows users to handle all alerts in one
place and track who acknowledges and clears issues. Charts and data
can be easily exported for deeper analysis. he TurbinePhD user
interface is completely web-based, so users can access all of their

turbine health data anywhere with an internet connection. he leet
view allows operators to assess the health of all wind farms at a
glance, and graphical health alerts clearly highlight those that need
attention. At the wind farm level, users can see which turbines have

new alerts or view and download charts of the most critical faults on
the farm. TurbinePhD is backed by RNRG’s two-year warranty and
lifetime technical support.
