Description
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 temperate, tropical, common, cold climate, and environmental class 2, as per GOST 15150-69.
Operating position - optional.
Design
CT Type TV-SVEL is a single-phase built-in current transformer.
This CT is designed for 0.66kV voltage class, and, therefore, can be installed at any voltage terminal provided that it ensures the set parameters, smooth operation and fit to the coupling size.
CT primary coil is a switch terminal or power transformer terminal passing through the internal round cross-section hole.
To obtain various ratios, the secondary coil has several taps. Secondary terminals of TV-SVEL are made of flexible conductor. Length of terminals shall be specified in the work order.
Design Features
Upon customer’s request, CT can be made with increased rated load of the secondary winding.
Upon customer’s request, CT may be made with non-standard dimensions, as well.
CTs for differential current protection can be manufactured subject to a special order.
