01
Artifact Overview
In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used--and then charge them accordingly. Induction-type wattmeters proved reliable and would become the industry standard, but until 1910 Westinghouse held the patent rights. Sangamo Electric Company introduced this induction-type meter -- the smallest model on the market at the time -- in 1911 after the Westinghouse patents had expired.

In 2015, The Henry Ford received a grant from the Institute of Museum and Library Services (IMLS) to digitize a selection of artifacts related to electric power generation and distribution. Many hidden stories came to light as staff cataloged, photographed, and conserved these objects. This expert set (the second in the series) presents just another small sampling of those artifacts and their stories preserved by The Henry Ford.
