HOW TO CHOOSE?

Current Transformers are devices that convert the alternating current passing through the main circuit, which we call "primary", into secondary windings in the order of the conversion rate with a magnetic coupling effect. The current transformers used for measurement purposes are connected to the secondary ends of the measuring and control devices, thus being isolated from the voltage on the primary side and ensuring safe operation.

Selecting a current transformer

• Busbar size, Operating voltage rated value (Un)

• Conversion rate (k)

• Accuracy Class (Measurement Accuracy) (cl)

• Application Type • Power of transformer (Nn)

• Primary current

• and product selections according to assembly come to the forefront.

There are many types of current transformers such as openable (separable) current transformers that provide ease of mounting even under energy during operation, sealed current transformers used in energy meteres used by distribution companies, mini current transformers that save space due to limited spaces in the electrical panel, bagel type current transformers used in generator transfer panels.

Current transformers manufactured with the latest technology in Sigma Electric plants are produced to make precise measurements for energy analyzers, multimeters, ammeters, compensation relays, protection relays and all other measuring devices used in industry. Especially thanks to the openable (separable) current transformers that can be easily installed without power interruption, losses due to stoppages in the enterprises can be prevented.

Sigma current transformers, which are produced from 20 A to 5000 A and made ready for use after passing all the necessary tests, provide easy fast installation thanks to Nickel-plated connection terminals.

Sigma Elektrik continues to produce solutions / products for all applications and needs in enterprises with both bagel type current transformers, mini type current transformers, sealed current transformers, busbar current transformers, openable current transformers and standard (perforated current) current transformers, which are the most widely used in the industry.
