This CT is intended for:
- transmitting signal to instruments and protective, alarm or control devices;
- electricity metering;
- isolating secondary 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.
Design
CT Type TOL-SVEL-10 is a single-phase support-type cast resin current transformer.
CT may have up to 3 secondary coils, each on their own magnet core. Primary coil terminals are connected to the top surface of CT. Secondary coil terminals are connected to the bottom of CT. CT can be made with front or bottom secondary terminals, as well.
Secondary coil terminals are sealed with a protective cover.
CT is made with one or several ratios, and ability to switch on primary or secondary side.
Upon customer’s request, CT can be made with increased rated load of the secondary winding, increased thermal and electrodynamic current
CT can have secondary terminals made of a flexible conductor. Length of terminals shall be specified in the work order.
CTs for differential current protection can be manufactured subject to a special order.
