Supporting current instrument transformers CTS

Supporting current instrument transformers CTS are designed for the measurement and protection of the distributingfacilities of high voltage for inner settings. Current transformers CTS 12 are produced in two arrangements: CTS 12.S and CTS 12.L. The difference of these two arrangements is only the length of the instrument (see the picture). (Dimension in brackets is for CTS 12.L.) The bigger dimensions of CTS 12.L allow to fulfill the more demandingtasks of the customer for the parameters of the instrument (3-cores arrangement, higher performance, higherovercurrent number, etc.). made of the...

Voltage instrument transformers VTS

Voltage instrument transformers VTS are single-phase transformers isolated with one pole. They are designed for the use in the high voltage systems. They are designed for measuring and protection of high voltage distributing equipment for indoor design. The instruments can be equipped with high voltage fuse protecting the surrounding distributing system. The instrument transformers VTS 25 Sch are modified for the use in the distributors SM6 of the firm SCHNEIDER ELECTRIC. The values of secondary voltage are 100/√3, 110/√3, 120/√3, 100/3, 110/3, 120/3 V. The accuracy classes for measuring...

WIRING DIAGRAM One end of primary winding is isolated from ground, the other is earthed during the operation. Before starting of the operation it is necessary to assure the earth connecti- on of one of the secondary terminals of every outlet (See „The Instructions for the operation and mounting"). In case of connection of auxiliary winding in the open tri- angle terminal has to be earthed at only one instrument The diagram of connection of three single-poled transformers ATTENTION! After every connection it is necessary to check if the secondary winding is not earthed by the me- ans of one...

Instrument voltage transformers VTS 38 P is necessary to accurately specify the version in the order.) If the fixed contact is used, a cable eye is recommended according to the cross section of the used conductor. The magnetic circuit of the voltage transformers is made of oriented transformer strips in the shape of the “C” core. All active parts of transformer are compound-insulated with epoxy-mixture. This material performs both the electrical insulating and the mechanical functions. The secondary terminal board is equipped with a cover and a sealing screw. There is an additional pack...

Voltage instrument transformer VTD Voltage instrument transformers VTD 12 and VTD 25 are single-phase transformers isolated with double-poles. They are designed for the use in the high voltage systems. They are designed for measuring and protection of high voltage distributing equipment for indoor design. The instruments can be provided with high voltage protectors protecting the surrounding distributing system.The values of secon- dary voltage are 100, 110, 120 V. The accuracy classes for measuring winding are 0.2, 0.5, 1, for the securing winding is 3P. The transformers satisfy required...

Magnetic circuit of voltage transformers is made of oriented transformer strips in the shape of “C” of core. All active parts of transformer are compound-insulated with epoxy-mixture. This material performs both the electrical insulating and the mechanical functions. Transformers are fixed by the means of four screws M10 in the holes in the basic plate. The primary terminals of transformers are brought out by the means of nuts M10. We recommend use terminal ends corresponding to the used cross-section of the conductor for attaching to the secondary outlets. The secondary terminal plate is...
