Current transformers ТОЛ-10-1000/5

Current transformers The transformers are intended for transmitting the measurement information signal to measuring instruments and to protection and control devices, and for isolating secondary circuits from high voltage in indoor and outdoor AC switchgear assemblies (КРУ, КРУН and КСО) for a voltage class of up to 10 kV at a frequency of 50 or 60 Hz. Transformers for differential protection are supplied to special order. The transformers are manufactured in versions "У" and "Т", placement category 2 according to ГОСТ 15150, and are intended for operation under the following conditions: altitude not more than 1000 m above sea level; the ambient temperature, taking into account air overheating inside the КРУ, is given in Table 1; the environment is non-explosive and free of dust, chemically active gases and vapours in concentrations that destroy metal coatings and insulation; operating position - any. The transformers are fitted with transparent protective covers for separate sealing of the secondary terminalsPatent protection Patent for invention No. 2089955. Table 1.
