Abstract:
A circuit is provided for energy metering and surge current detection. It uses a current transformer. A first current sensing arrangement is connected to the secondary side of the transformer for energy metering and a second current sensing arrangement is connected to the secondary side, with a high pass filter, for surge current detection. A single component is thus able to provide energy metering and surge detection.
