What is the purpose of bushings in CT?
Bushing Current Transformers (BCTs) are used for a variety of measuring, revenue metering and protection applications. Peak Demand BCTs are designed and manufactured in accordance to customer specifications and can be tested to the applicable IEEE, IEC or GOST standards.
What is the use of bushings in transformer?
In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it.
Why is CT used in transformers?
A Current Transformer (CT) is used to measure the current of another circuit. In doing so, the current transformer reduces a high voltage current to a lower value and therefore provides a safe way of monitoring electrical current flowing in an AC transmission line.
What is difference between bushing and bearing?
A bushing is a thin tube or sleeve that allows relative motion by sliding (our type), as compared to rolling. A bushing might also be called a sleeve bearing. A bearing is the general term for something that allows relative motion between two components, surfaces, etc. Learn more about what a bearing is.
What is the purpose of using CT?
CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
What is the benefit of CT over shunt?
Current shunts generally provide greater accuracy over a broader frequency range than current transformers (CT’s). Rather than measure actual in-series current flow, the indirect, inductive magnetic-field principle employed by current transformers is subject to a variety of potential error sources.
Which is better bushings or bearings?
Advantages of plastic bushings Plastic bushings have a lot of operational advantages. They are self-lubricating, thus they are maintenance free and have a low coefficient of friction. Plastic lends itself best to simple plain bearings, because it reduces both weight and maintenance, and you won’t see any brinelling.
