TUP80RV Low power CTs

Designed for smart grid monitoring. SACI’s low power current transformers are designed for direct installation on insulated medium voltage cables. The resin encapsulation and plastic casing allow the transformer to be installed directly outdoors without any deterioration in its characteristics.

Connections

Dimensions

This transformer can have a different colour P1 side to make the polarity easy to distinguish.
The secondary connection is made with a cable terminated with an RJ45 connector, pins 1 (S1) and 2 (S2).

Mounting on isolation panels on distribution cabinets in medium voltage substations.
