Question

Accepted Answer

Answering questions about instrument transformers and star connection in transformers.

Different types of instrument transformers include current transformers and potential transformers.
Current transformers are used to measure high currents while potential transformers are used to measure high voltages.
Star connection in transformers is a three-phase connection where the three phases are connected to a common point, forming a star shape.
This connection is used to supply power to three-phase loads such as motors and generators.
The star connection can be either a grounded star or an ungrounded star, depending on whether the common point is grounded or not.

Accepted Answer

Ther are two types of instruments transformer. First is Current Transformer.Current Transformer is measured by Current . Second is Potential Transformer is measured by Voltage.
