Current Transformer Bar Type
Newtek Bar type current transformers are designed to be mounted in-line with bus bars, making them an integral part of power distribution systems. These CTs are fully insulated to withstand the high voltages present in switchgear applications. The construction of a bar type CT involves several key elements that contribute to its functionality and reliability.
The primary winding of a bar type current transformer consists of a single turn primary conductor, which is typically a fully insulated bar. The insulation on the primary winding conductor can either be a bakelized paper tube or a resin directly molded on the bar. This insulation ensures the safety and integrity of the primary winding in high voltage environments.
The secondary winding of a bar type CT is wound on a core, which is similar to other types of current transformers. The core is made up of laminated steel or other suitable materials to minimize magnetic losses. The secondary winding consists of multiple turns, and the number of turns is determined by the desired turns ratio.
Advantages of Bar Type Current Transformers
- Fully insulated design for safe operation in high voltage environments.
- Accurate current measurement with low burden on the secondary winding.
- Wide range of turns ratio options for precise current monitoring.
- Robust construction to withstand short circuit forces and mechanical stresses.
- Flexibility in installation and assembly, with options for on-site assembly.
Applications of Bar Type Current Transformers
- Power distribution systems in commercial and industrial settings.
- Electrical substations for accurate monitoring of current levels.
- Power generation plants for reliable current measurement.
- Renewable energy systems, such as solar and wind farms.
- High voltage applications where insulation and safety are critical.
