Bus-bar current transformers ТШЛ-0,66 (TSHL-0,66)

Bus-bar current transformers TSHL-0,66; TSHL-0,66-I; TSHL-0,66-II and TSHL-0,66-III

Current transformer TSHL-0.66Application

The transformers are intended for embedding in factory-assembled transforming station and for transmitting of the measuring information signal to measuring instruments and to protection, automatic control and signaling devices. The transformers for differential protection are delivered at the special order.
The transformers are manufactured in climatic versions "M" (moderate) and "Т" (tropical) according to the standard requirements of GOST 15150 location category 3 and are intended for usage under the following operating conditions:

  • altitude above sea level is not higher than 1000 m;
  • ambient air temperature within operation period is from minus 45 °C to plus 70 °C for "M" version and from minus 10 °C to plus 70 °C for "T" version, during transportation and storage periods from minus 50 °C to plus 70 °C for "M" version and from minus 50 °C to plus 70 °C for "T" version;
  • air humidity is 98% at 25°C for "M" version and at 35°C for "Т" version without moisture condensation;
  • environment should be non-explosive, without corrosive steams in concentrations that are likely to destroy metal or insulation (atmosphere type II as to GOST 15150);
  • mounting in any position.

The transformer is patented
Priority-driven Certificate № 99118385 given on 31.08.99
