The combined instrument transformer (CTVT) offers the station designer the ability of being able to accommodate the current transformer and the voltage transformer in one free-standing unit. This allows optimum use of substation space while yielding cost savings by elimination of one set of mounting pads and support structures. In addition, installation time is greatly reduced.
Features :
Meets all latest IEC and IS metering and protection classes, including special core classes (other standards available on request)
Low weight & minimum oil volume design. Available in both single phase and three phase design
High accuracy up to 0.1 and 0.2s class. Rated primary currents up to 3000 A
Rated secondary current 1 A or 5 A. Rated short circuit withstand up to 40 kA for 3 secs
Highly refined and processed oil/paper insulation system. True hermetical sealing
Uniformly distributed secondary windings guarantee accurate transformation at both rated and high currents
Stable accuracy over a long period of time
Successful field experience since the manufacture of the first CTVT in 2001
CTs are virtually maintenance free during a long lifetime
Only one foundation required in the switchyard as a consequence of combining the voltage and current sensing functions in one transformer
Widely replacing the galvanic isolators and polarity alarms, the Isolation Transformer, which we manufacture and provide, is appreciated for its ability to eradicate any electrical continuity between AC shore power and the boat. The Isolation Transformer, which we offer, provides the best resistance against galvanic corrosion. We are Indore (Madhya Pradesh) based reliable Manufacturer and Supplier of the Isolation Transformer.
