Supporting current instrument transformers CTS 25 Sch are designed for the measurement and protection of the distributingfacilities of high voltage for inner settings.
Supporting current instrument transformers CTS 25 Sch are arranged for the using in the distributors SM6of the firm SCHNEIDER ELECTRIC.
The value of the secondary current is 5 A or 1 A with the possibility of combination. The classes of accuracy for the circuits of measurement are 0.2, 0.5, 1.3, for the circuit of protection are 5P, 10P. The transformers comply with the required class of accuracy within the values from 25% to 100% of rated load.
The limiting working current is 120% of IN ,according to the agreement of producer and customer it is possible tosupply other values, for example 200% of IN.
Transformers CTS are constructed as transformers with single-turn or multi-turn primary winding. The up-to-date construction of these transformers allows the switching not only on the secondary side but also on the primaryone. The primary switching can be easily mounted by the means of connection of two jumpers to the circuit by the means of two screws M8 (See "The Instructions for the mounting and operation". Screws and jumpers are the partof the transformer).
