The Challenge

To check the calibration of current transformers on site without the need to remove them to a calibration laboratory.

To provide a portable precision current-measurement standard which can be clipped on to the CT wiring without disconnecting any conductors.

Our Solution

Rocoil rigid coil systems can be calibrated to an uncertainty of 0.1%. They can also be produced in a clip-on version without loss of accuracy. These can be used as reference standards for calibration.
