TT 50-SD

TT 50-SD is an AC current transformer. It split core transducer for the electronic measurement of AC waveform currents, with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement). Application includes current measurement for active power calculation (power meters), for energy efficiency monitoring, consumption analysis and costs allocation (energy sub-meters), power quality monitoring, condition monitoring, distributed measurement systems, Energy and automation (application domain).
