What You Need to Know about Current Transformers

Current transformers are electrical device that aids in protecting your appliances at home or office. They provide flow of current in secondary circuit that is directly proportional to the amount of current in principal circuit. Current transformers are used to monitor the operation of power grid and calculate the current.

Electrical power industry utilizes current transformers for protective and metering purposes. The transformers manage the flowing of current especially if it comes from a high voltage-producing source. The well-insulated toroidal core being wrapped with windings of massive wires serve as the controlling passage of the electrical current, avoiding circuit overload. The power being used by a certain establishment is monitored because with this kind of transformer, you can have a view of how much current is flowing.

The physical configuration of current transformer, rating factor, and many others are factors that improve the accuracy of current transformer’s measurement and workability.

Ambient temperature is the basis of CT rating factor. The rating factor is used to identify the appropriate primary current measurable at maximum level. It regulates the current by multiplying the fill load. The current transformer would have low capacity in order to retain the level of precision in terms of measurement. The temperature of CT should have ranged from 35-55 degree Celsius.

Visit TechRentals for more information about current transformers. The Australian company offers test and measurement equipment for hire, lease or rent.

  2. Test Equipment Hire
    Transformers and other test equipment nowadays are available for hire or rent. It is most suitable for those who have tight-budgets and still want to ensure safety in their premises.
