ATO series is a split core current transformer for the electronic measurement of AC waveform current with galvanic separation between the primary circuit (power) and the secondary circuit (measurement).

ATO series is an ideal current transformer for new Smart-Grid applications, in which ratio error and phase displacement are fully tested with IEC 61869 standards accordance.
