Description
Transformers TV-SVEL-35 (110, 220) -IX are intended for:
- for transmitting a signal of measuring information to devices of measurement, protection, automation, signaling and control;
- for commercial metering of electricity;
- for isolating secondary connection circuits from high voltage.
CTs are made for boreal climate and tropical climate, and environmental class 2 as per GOST 15150-69.
Operating position - optional.
Current transformers TV-SVEL-35 (110, 220) -IX are single-phase, according to the design principle they are built-in, with cast resin.
The primary winding of the transformer is the high-voltage bushing of the circuit breaker, the power transformer or the linear bushing passing through the inner round window.
The outputs of the secondary windings, intended for measuring and metering electricity, are additionally closed with a sealed cover.
The contact panel is closed with a cover for protection against atmospheric precipitation. At the request of the customer, to ensure tightness, it is possible to supply transformers with sealing collars at the point of exit of the connection cable from the terminal panel.
Transformers are manufactured with one or more secondary windings (up to six inclusive). To obtain different transformation ratios, the secondary windings can have several taps.
At the request of the customer, it is possible to manufacture transformers with increased rated loads of secondary windings, and it is also possible to manufacture transformers with installation dimensions that differ from the standard ones.
Differential protection transformers are available on request.
