The purpose of the article is to study the conditions which guarantee that a contribution of the so-called singular part of a measure into \((1,p)\)-capacity of an arbitrary capacitor is zero.
The main result reads as follows: Let \(E\subset D \subset \mathbb R^n\) be a set of Hausdorff linear measure zero. Then every finite regular Borel measure with support in \(E\) is \(p\)-trivial.
