Support-type current transformers ТОП-0,66 (TOP-0,66) and bus-bar transformers ТШП-0,66 (TSHP-0,66)

Support-type current transformers ТОП-0,66 (TOP-0,66) and bus-bar transformers ТШП-0,66 (TSHP-0,66)

Current transformers TOP-0,66Application

The transformers are intended for transmitting of the measuring information signal to the measuring instruments in the alternate current equipment with the frequency 50 or 60 Hz and rated voltage value up to 0,66 kV inclusive.
The transformers of the accuracy class 0,2, 0,5, 0,2S, 0,5S can be used in accounting schemes in customer calculations, and those of the accuracy class 1 - in the measuring schemes.

The transformers are manufactured in climatic versions "Y" (temperate) and "T" (tropical) according to the standard requirements of GOST 15150 location category 3. The transformer is intended for usage under the following operating conditions:

altitude above sea level is not higher than 1000 m; ambient air temperature: within operation period - from minus 50 °C to plus 50 °C, within transportation and storage periods - from minus 50 °C to plus 50 °C; ambient air humidity is 98% at 25 °C; environment should be non-explosive corresponding to atmosphere II GOST 15150, without dust, reactive steams and gases in concentrations that are likely to destroy metal or insulation; mounting in any position.

Current transformers TSHP-0,66Support transformer TOP-0,66 is supplied with copper bus-bar sheath with tin. Transformer TSHP-0,66 may be supplied with copper bus-bar sheath with tin.

The transformer body is made from hard inflammable self-extinguishing thermoplastic.

The transformer is patented
Patent Certificates 42734, 42735, 42736,48549, 48550 и 48551 on industrial units.
