  Let $K$ be a local field of characteristic $p$ and let $L/K$ be a totally
ramified elementary abelian $p$-extension with a single ramification break $b$.
Byott and Elder defined the refined ramification breaks of $L/K$, an extension
of the usual ramification data. In this paper we give an alternative definition
for the refined ramification breaks, and we use Artin-Schreier theory to
compute both versions of the breaks in some special cases.
