UTA 210

It is an advanced tool designed to perform accurate measurements of all relevant Current Transformer (CT) parameters in order to compare them with the requirements established by IEC or IEEE standards. This tool plays a crucial role in checking the compliance and performance of TCs, ensuring that they meet international quality and safety standards.
