Measurement.Categories

These definitions were derived from the international safety standard for insula-
tion coordination as it applies to measurement, control, and laboratory equipment.
These measurement categories are explained in more detail by the International
Electrotechnical Commission; refer to either of their publications: IEC 61010-1 or
IEC 60664.
Measurement.Category.I
Signal level. Electronic and telecommunication equipment, or parts thereof. Some
examples include transient-protected electronic circuits inside photocopiers and
modems.
Measurement.Category.II
Local level. Appliances, portable equipment, and the circuits they are plugged into.
Some examples include light fixtures, televisions, and long branch circuits.
Measurement.Category.III
Distribution level. Permanently installed machines and the circuits they are hard-
wired to. Some examples include conveyor systems and the main circuit breaker
panels of a building's electrical system.
Measurement.Category.IV
Primary supply level. Overhead lines and other cable systems. Some examples
include cables, meters, transformers, and other exterior equipment owned by the
power utility.
