Electrical
measurements are critical to industries that rely on electricity for
production continuity. After all, aside from potential interruptions
due to sudden current flow changes, over fusing can lead to fires and
increased current flow through the wires. Constant monitoring of the
current flow using measuring instruments, such as an ammeter, is
imperative in any electrical system.
Unfortunately,
most measuring instruments cannot take the current flowing through
live wires. Like how electricity can severely injure living things
that come into contact with an open electrical source, so does the
circuitry inside these instruments burn when subjected to excessive
currents. An electrical measuring instrument has to be protected so
it can continue to measure alternating current without the risk of
over fusing.
