[0002] High-voltage cables are widely used in high-voltage power transmission and transformation networks, and are mostly installed via direct burial, tunnels, or cable bridges. To fully understand the cable's real-time status, online monitoring is often employed. This involves installing online monitoring equipment, such as circulating current monitoring devices and cable induction energy harvesting devices. Each monitoring device is typically equipped with a transformer housing and a current transformer. These instruments use the principle of electromagnetic induction to convert high primary currents into low secondary currents for measurement. They consist of a closed iron core and windings. The primary winding has a small number of turns and is connected in series with the current being measured.
