earth reference plane (ERP)

An earth potential reference surface (ERP) is a conductive surface that is connected to the earth potential.

The earth potential reference surface can be a wire mesh or a mat with a conductive undersurface. Such an earth potential reference surface is used in Electrostatic Protected Areas (EPA) at workplaces in electronics manufacturing and semiconductor production, as well as in test engineering and measurement technology, and ensures that the measured object, the measuring equipment and the operator have a uniform reference potential.
