Current Transformers and Its Factors

A current converter is an electric instrument. It is used to produce a flow in secondary circuit current that is exactly perpendicular to primary circuit current. This is used to calculate current, monitor power grid operation and are commonly known as Current Transformers. It is defined as the current ratio of primary and secondary. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.

These current transformers are widely used in metering, and protective relaying within the electrical power industry. This allows them to make the most of large currents while maintaining safety in high voltage circuits. The current transformer cuts off securely to measure and manage the circuitry using the highest voltage that is available. Control of current transformers is done by passing through one primary turn in a well-insulated cylindrical core with many turns wire wrapped. The current transformer can also be used to measure current flow and monitor power usage. The CT is fundamentally determined by the current ration that flows from primary to second.

Some factors increase the accuracy of the current transistors. They include: rating factor, burden, physical CT configuration, etc.

The result of the burden in a Current transformer circuit is called the value for impedance. The primary items that create burden in a current calculation circuit include intermediate conductors meters and switch blocks meters. Additionally, the source of the high resistance is the CT.

The Rating Factor of current converters that are dependent upon ambient temperature is a factor used for determining the correct maximum measurable prime current by multiplying a CT’s full load. To ensure accuracy in rising ambient temperature, CT’s will have low capacity. The rating factors of CT’s range from 35 to 55 degrees Celsius.
