Rogowski coils are an alternative current measuring device to Current Transformers. The main difference between these two current measuring devices is the method of operation. Current Transformers use a cheaper magnetic metal core which can saturate and lose accuracy if it is not correctly sized. Rogowski coils use a non-magnetic core that is non-saturable and therefore does not have the same restrictive installation requirements. The properties for Rogowski Coils make them suitable for applications where:
- The conductors are far from the electricity meter location
- There are physical restrictions on the installation that the prohibit the use of non-flexible current transformers
- Where large currents need to be measured
- Where the primary circuit cannot be broken or isolated
The installation of the Rogowski Coils is straight forward, they most be closed around the conductor, then connected to a power supply and a 0.333V input electricity meter.
