The Current Transformer is a sensor placed around a high-current electrical conductor. It steps down the current to a proportional, lower value suitable for measurement instruments. This enables monitoring of electrical loads within. It protects relaying by providing accurate current signals to trigger protective devices, ensuring the equipment operates within safe limits and minimizing the risk of damage from overcurrent events.Attributes:• Safely isolates measuring instruments from high-voltage circuits.• Provides high accuracy in current measurement for exact monitoring.• Offers high insulation resistance to enhance safety.Applications:The Current Transformer is located around the main power lines or conductors positioned to measure the actual current flow and provide a scaled-down representation for monitoring and protection purposes.
