Definitions:

Ayrton Shunt

An ammeter shunt that permits multiple range values.

Current Transformer

A transformer used for metering alternating current. Current transformers generally have a standard output current value of 5 A at rated primary current.

Moving Vane

A mechanical component in some measurement devices that moves in response to an external physical quantity, such as fluid flow or electrical current.

High Resistance

A characteristic of materials or components that oppose the flow of electric current, resulting in a low current for a given applied voltage.
