A Transformer is designed to accurately measure and step down high-current signals into a more manageable range. When a high-current signal is applied to the primary winding, an alternating magnetic field is generated within the transformer's magnetic core. This field induces a proportional current in the secondary winding according to the turn ratio. The secondary winding output is then connected to measuring or protective devices, such as current meters or relays, to monitor or control the current flowing in the primary circuit.

Attributes:
• Provides electrical insulation, mechanical protection, and environmental resistance
• Ensuring a high degree of accuracy and linearity

Applications:
A Transformer is employed in protective relaying schemes to detect fault conditions and trigger appropriate actions to safeguard electrical equipment and enable real-time measurement and analysis of current flow for load management, power quality assessment, and energy efficiency optimization.
