Sudden short circuit testing of large generators
At a glance
To measure a very large current transient with an asymmetric waveform.
Transients are difficult to measure with a conventional current transformer and the usual method is to use a resistive shunt which can be difficult to install and may require modification of the generator output connections.
We designed a Rogowski coil to measure very large transient currents. It was compact and was installed on the output connections with no significant disruption to other work on the generator. It was left in position until it was convenient to make the short-circuit measurements.
