sliprings and brush holders

[Kamola]

Пожалуйста, помогите перевести.

Слово встречается в следующем контексте:

Unit # 2 was hand tripped after getting rotor earth fault. It was found that sparking had occured in the excitation system - sliprings and brush holders. There was fluctuation in the excitation current . Prima facie, this happened due to holder getting loose and touching the slipprings. CO2 extinguishers were used to put of the fire sparks. Timely action has averted further loss. There is pitting mark on the sliprings and we need to machine the sliprings
