Split Core Current Transformer
The split core current transformers are designed for fast and easy installation. They are ideal for installation on existing electrical cables by clamping on the conductor. This method permits a safer, easy and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary.
