Answer Posted / Minaxi Gautam
An Open Delta PT (Current Transformer) consists of three individual single-phase current transformers connected in delta configuration. The primary side has three wires, while the secondary side has a star connection. During operation, the primary circuit's current flows through the primary windings of each current transformer. The magnetic fields generated by these currents interact with each other, creating a resultant magnetic field that is measured on the secondary side.
