Mini Split-Core Current Measurement Transformer

Application:

Designed for incorporation into products used for electric power measurement, electric power quality monitoring, Supervisory Control and Data Acquisition (SCADA). The CTSA is particularly advantageous in applications that take advantage of the small physical size and split-core design to mount the current transformer in confined spaces while the primary conductor is “live“. The CTSA features exceptional transformation accuracy and minimal phase shift while exposed to high primary voltages and harsh operating conditions.
