In current transformers the primary is typically a ... resistor is used to detect the current in the secondary. Clamp meters use this principle to make non-contact current measurements.
The secondary voltage has a fixed relationship to the primary voltage so that a change in potential within the primary circuit is monitored accurately by meters connected across the secondary ...
Commercial The commercial class transformers are well suited for low power current monitoring applications. ANSI Class The ANSI metering class transformers are units ...
