Brush models
In general, type L and type S grounding brushes are suitable for mechanical drive units and small turbine generators.
Type LW grounding brushes are suitable for systems in power plant control centers with an output of 100 MW to over 1,000 MW.
The type A grounding brush is particularly suitable for axial installation against a shaft end or the shaft collar, even for retrofitting during operation.
Of the smaller brushes, the type L dissipates around four times as much current as the type S with the same wear rate of the bristles. For this reason, the type L brush is the most economical of the small brushes and therefore has the longest replacement interval for bristle elements.
