Dimensions of the device current transformer TSHP-0,66-I are shown in Figure 1;
 
Figure 1 Dimensions of the device current transformer TSHP-0,66-I
 
TSHP-0,66-I - Current transformer - Drawing.
 
Weight:
- No tires - 0.7 kg;
- Bus - 0.9 kg;
One-minute test voltage instrument transformer current TSHP-0,66-I frequency - 3 kV;
Transformers of accuracy class 0,2; 0,5; 0,2 S and 0,5 S used in accounting schemes customer calculations, accuracy class 1.0 - in schemes of measurement;
The main advantages of instrument current transformers TSHP-0,66-I are given below;
Currently transformers produced at full standard range of rated primary current, while keeping accuracy classes as 0.5 and 0.2, and 0,5 S and 0,2 S, which allows to use them widely in computer-aided control and metering AMR ;
CT devices TSHP-0,66-I have several degrees of protection from unauthorized access:
- Transparent protective cover for sealing, protecting the secondary contacts, rating plate and the stamp, and ensures the safety of operation.
- Protective sticker that when trying to parse the transformer is broken, leaving visible signs of tampering;
The modern design and design tool CT TSHP-0,66-I allow the use of transformers with primary cable or bus and configuration of various sections, as well as install them in any position;
Availability of built-Cu coated with tin, it allows you to connect both copper and aluminum conductors;
Hazard CT TSHP-0,66-I provides a self-extinguishing plastic housing with high insulation class;
Shells themselves have three different colors - yellow, green and red, which is a common phase segregated marked;
Transformers are packaged in easy-to-consumer bottles, three pieces;
CT devices TSHP-0,66-I are absolute counterparts type transformers GPT-0 ,66-I;
Mount transformer by using the reference tabs or DIN-rail;
The new instrument current transformer TSHP-0,66-I has a convenient mounting potential output, which is in a sealable junction box;
The use of products of modern terminals can quickly be assembled secondary circuits;
 
The transformers are manufactured in model "U" or "T", are designed to operate under the following conditions:
Height above the sea level - no more than 1000 m.
Ambient temperature
- In operation - from -45 ° C to +50 ° C;
- Transport and storage - from -50 ° C to +50 ° C;
- Environment explosive, without dust, reactive gases and vapors in concentrations destroy metal and insulation;
- Working position - any;
Initial CT Bus device TSHP-0,66-I copper, tin-plated;
Warranty period - 8 years from the date of entry into operation of the transformer, but not more than 8.5 years from the date of shipment from the factory;
Service life CT TSHP-0,66-I - 30;
The unit is equipped with protective transparent cover for separate sealing of secondary findings;
Minimum permissible load current transformer unit TSHP-0,66-I for the windings of accuracy class 0,2 S and 0,5 S is 1B · A;
The certificate on the current transformers with secondary windings for accounting accuracy classes 0,2 S and 0,5 S indicates the measured current and the angular error at rated secondary burden 1B · A;
The manufacturer guarantees that the quality of the instrument current transformer TSHP-0,66-I to the technical requirements specifications provided the customer terms and conditions of storage, transportation, installation, operation, and its specified operational documentation.
